The restoration of the frescoes of the Sistine Chapel was one of the most significant art restorations of the 20th century.The Sistine Chapel was built by Pope Sixtus IV within the Vatican immediately to the north of St. Peter's Basilica and completed in about 1481. French Macaron Pillow ,Creative Cushion - Matty's

Its walls were decorated by a number of Renaissance painters who were among the most highly regarded artists of late 15th century Italy, including Ghirlandaio, Perugino, and Botticelli.[1] The Chapel was further enhanced under Pope Julius II by the painting of the ceiling by Michelangelo between 1508 and 1512 and by the painting of the Last Judgment, commissioned by Pope Clement VII and completed in 1541, again by Michelangelo.[2] French Macaron Pillow ,Creative Cushion - Matty's

Individually, some of Michelangelo's paintings on the ceiling are among the most notable works of western art ever created.[a] Sony VAIO PCG-31111M battery

The frescoes of the Sistine Chapel and in particular the ceiling and accompanying lunettes by Michelangelo have been subject to a number of restorations, the most recent taking place between 1980 and 1994. This most recent restoration had a profound effect on art lovers and historians, as colours and details that had not been seen for centuries were revealed. Sony VAIO PCG-31112M battery

It has been claimed that as a result "Every book on Michelangelo will have to be rewritten".[3] Others, such as the art historianJames Beck of ArtWatch International, have been extremely critical of the restoration, saying that the restorers have not realised the true intentions of the artist. This is the subject of continuing debate.

The frescoes on the ceiling of the Sistine Chapel had a number of interventions prior to the restoration process which was started in 1980. Sony VAIO PCG-31113M battery

Initial problems with the ceiling appear to have been caused by water penetrating through the floor above. In about 1547 Paolo Giovio wrote that the ceiling was being damaged bysaltpetre and cracks. The effect of saltpetre is to leave a white efflorescence. Gianluigi Colalucci, Head Restorer at the Laboratory for the Restoration of Paintings for Papal Monuments, Sony VAIO PCG-31114M battery

Museums and Galleries, states in his essay Michelangelo's colours rediscovered,[4] that the early conservators treated this cosmetically by an application of linseed or walnut oil which had the effect of making the crystalline deposit more transparent.

In 1625, a restoration was carried out by Simone Lagi, the "resident gilder", who wiped the ceiling with linen cloths and cleaned it by rubbing it with bread. Sony VAIO PCG-31111V battery

He occasionally resorted to wetting the bread to remove the more stubborn accretions. His report states that the frescoes "were returned to their previous beauty without receiving any harm".[5] Colalucci states that Lagi "almost certainly" applied layers of glue-varnish to revive the colours but does not state this in his report in the interests of "preserving the secrets of their [the restorers'] craft".[4] Sony VAIO PCG-31112V battery

Between 1710 and 1713 a further restoration was carried out by the painter Annibale Mazzuoli and his son. They used sponges dipped in Greek wine which Colalucci suggests was necessitated by the accretion of grime caused by soot and dirt trapped in the oily deposits of the previous restoration. Mazzuoli then worked over the ceiling, according to Colalucci, strengthening the contrasts by overpainting details. Sony VAIO PCG-31113V battery

They also repainted some areas the colours of which were lost because of the efflorescence of salts. Areas of repainting were hatched or treated with a linear brushstroke.[b] Colalucci states that Mazzuoli also applied a great deal of glue varnish. The restoration concentrated on the ceiling and less attention was paid to the lunettes.[4]

The penultimate restoration was undertaken by the Restoration Laboratory of the Vatican Museum between 1935–38. Sony VAIO PCG-31114V battery

The scope of the work was to consolidate some areas of the intonaco at the eastern end of the building and partially remove the soot and dirt.

The preliminary experimentation for the modern restoration began in 1979. The restoration team comprised Gianluigi Colalucci, Maurizio Rossi, Piergiorgio Bonetti, and others,[6] Sony VAIO PCG-GRS100 battery

who took as their guidelines the Rules for restoration of works of art as established in 1978 by Carlo Pietrangeli, director of the Vatican's Laboratory for the Restoration of Pictures, which govern the procedure and methods employed in restoration. An important part of modern restoration procedure, as established by these rules, is the study and analysis of the artwork.[4] Part of this was the recording of every stage of the restoration process. Sony VAIO PCG-41111M battery

This was done by the photographer Takashi Okamura for Nippon Television Network Corporation.[7]

Between June 1980 and October 1984 the first stage of restoration, the work upon Michelangelo's lunettes, was achieved. The focus of the work then transferred to the ceiling, which was completed in December 1989 and from there to the Last Judgment.Sony VAIO PCG-41112M battery

The restoration was unveiled by Pope John Paul II on 8 April 1994.[8] The final stage was the restoration of the wall frescoes, approved in 1994 and unveiled on 11 December 1999.

In 1979 Colalucci undertook a series of experiments to discover the right approach for the restoration of the frescoes of the Sistine Chapel. Sony VAIO PCG-41111V battery

The investigation began by testing small areas of the wall fresco, Conflict over the Body of Moses by Matteo de Lecce, which had similar physical and chemical attributes to the painting techniques employed on Michelangelo's frescoes. Trials to find the right solvents were continued on a small portion of the Eleazar and Matthan lunette.[4] SONY VAIO PCG-6Q1L CPU Fan

Because of the height of the ceiling and the inaccessibility of the ceiling frescoes, the precise nature of the damage and the problems that would be encountered by the restoration team could not be entirely foreseen until after the decision to restore was taken, and the scaffolding was in place.SAMSUNG N150 Laptop Keyboard

According to Colalucci, the continued scientific analysis and the response of the restorers to the particular problems was an ongoing part of the process, rather than the conservation team deciding on a single treatment for every part of the building.[4]In 1980 the decision to undertake a total restoration was taken. Nippon Television Network Corporation of Japan provided major funding of US$4.2 million in exchange for the filming rights. HP Pavilion DV9243EA Laptop Keyboard

The team of restorers completed the first stage of the restoration, on the vertical surfaces and curved spandrels around the upper sections of the windows, from aluminium scaffolding projecting from just below the lunettes and using the same holes in the wall that had been made for Michelangelo's scaffold. When they moved to the ceiling, they likewise employed a system similar to Michelangelo's, FUJITSU Lifebook E8110 Laptop Keyboard

which involved cantilevering a shelf outwards from the scaffolding to support a stepped and arched platform. The advantages of modern lightweight materials meant that the platform could be wheeled, facilitating easy movement along the length of the building rather than dismantling and replacement, as Michelangelo had done in 1506. Lenovo 3000 Y500 Laptop Keyboard

The findings of the investigation of 1979 were that the entire interior of the chapel, but particularly the ceiling, was covered with a grime of candle smoke comprising wax and soot (amorphous carbon). Above the windows (the main source of ventilation), the lunettes were particularly stained from the smoke and exhaust fumes of the city, being "much dirtier than the ceiling proper".[7] HP Pavilion DV8310CA Laptop Keyboard

The building was a little unstable and had already shifted considerably prior to Michelangelo's work of 1508, causing cracking of the ceiling, the crack in the "Judith" pendentive being so large that it had to be filled with bricks and mortar before painting. The upper part of the ceiling provided Michelangelo an irregular surface due to cracks and water seepage.[1]  Lenovo 0A62039 Laptop Keyboard

Continued ingress of water from the roof and from unroofed exterior walkways above the ceiling level had caused seepage which carried down salts from the building mortar and deposited them on the ceiling through evaporation. In places this caused the surface of the frescoes to bubble and lift. Although discolouration was a serious problem, bubbling was not, DELL Vostro 3450 Laptop Keyboard

because the thinness and transparency of the paint which Michelangelo employed on the greater part of the ceiling permitted the salts to pass through rather than accumulating beneath the surface.[4]

Earlier restorations had all left their marks on the frescoes. To counteract the whitening caused by salination, animal fat and vegetable oil had been applied, which effectively made the salt crystals transparent, but left a sticky layer that accumulated dirt. TOSHIBA Mini NB 505-SP0160 Laptop Keyboard

An additional problem, most obvious in the small putti which hold the nameplates on the pendentives, was saltpetre seeping through small cracks and appearing as dark rings on the surface. Unlike the white crystalline salt deposits, this could not be removed and the staining was irreversible. Layers of varnish and glue had been applied to many areas.  Lenovo 3000 G530 4151 Laptop Keyboard

This had darkened and become opaque. Restorers had repainted details over the darkened areas in order to define the features of figures. This was particularly the case for the lunettes, spandrels and lower parts of the pendentives.[4]

Close examination revealed that apart from smoky deposits, seepage deposits and structural cracks, the thin "pictorial skin" of Michelangelo's frescoes was in excellent condition.[4] SAMSUNG N150 Laptop Keyboard

Colalucci describes Michelangelo as having employed the best possible fresco techniques, as described by Vasari.[11] Most of the paint was well adhered and required little retouching. The plaster, or intonaco, on which the paintings were executed was found, for the most part, to be secure, as previous restorers had fixed it in places with bronze pins. HP G61-400SP Laptop Keyboard

Prior to the restoration the team spent six months investigating the composition and condition of the frescoes, questioning members of the team that had restored the frescoes in the 1930s and making a detailed scientific study to ascertain which solvents and methods were best employed upon particular painted surfaces.

The first stage of the physical restoration was to re-attach any areas of the plaster surface (which was approximately 5 mm thick) that were in danger of separating and breaking away. COMPAQ Presario CQ40-133TU Laptop Keyboard

This was done by injecting apolyvinylacetate resin. Earlier bronze braces that had been used to stabilise surfaces were removed in those places where they were causing cracking, and the holes filled. Pigments that appeared to be not well adhered were consolidated with the application of diluted acrylic resin.[4]

The restorers washed the surfaces using a variety of solvents. Distilled water was used wherever possible to remove soot and dissolve water-soluble gums. HP 317443-001 Laptop Keyboard

Retouching and repainting that had been part of previous later restorations were removed with a gelatinous solvent, applied in several stages for measured times, and washed with distilled water. Salt efflorescences of calcium carbonate were treated by the application of a solution of dimethylformamide. The final step was the application of a weak solution of acrylic polymer to consolidate and protect the surface, and further washing.[4]  HP HDX18-1200 CTO Laptop Keyboard

Where necessary some areas were retouched in watercolour, to integrate the pictorial material. These areas are distinctively textured with vertical brushstrokes, not visible from a distance but easily discernible as restoration work when viewed close up.[4]

Certain small areas were left unrestored, in order to maintain a physical record of the previous restorations that had taken place, DELL Vostro 1014 Laptop Keyboard

for example, an area left with overpainting and candle wax, and another area demonstrating the attempt to counteract salination with oil.

Once the many layers of candle wax, varnish, and animal glue were removed from the surface of the Sistine Chapel frescoes, they became subject to dangers that could not have been predicted by previous restorers. SONY Vaio PCG-K215S Laptop Keyboard

One of the major dangers to the frescoes is automotive exhaust, and they are also vulnerable to the effects of the crowds of tourists that pass through the chapel every day, bringing with them heat, humidity, dust and bacteria. The clean plaster surfaces are more in danger from these destructive elements than they were when they were covered with a layer of smoky wax.[12] TOSHIBA Mini NB 300 Series Laptop Keyboard

Previously, the Sistine Chapel's only ventilation was from its windows in the upper level of the walls. To prevent exhaust fumes and wind-blown pollutants from entering, the windows are now permanently closed and an air conditioning system has been installed. The installation is by Carrier of the United Technologies Corporation and was developed with the cooperation of the Vatican's Office of Technical Services. GATEWAY NV-54 Laptop Keyboard

It has been designed to counteract the various problems specific to the Chapel, in particular the rapid changes of heat and humidity that occur with the admission of the first crowds of tourists each morning and the departure of the last visitors each afternoon. The air conditioning varies not only the heat but also the relative humidity between the summer and winter months so that changes to the atmospheric environment occur gradually. The air near the ceiling is kept at a temperate level, while the air in the lower section of the building is cooler and circulates more rapidly, with the effect that dirt particles fall towards the floor rather than being streamed upwards. Lenovo 3000 G530 4151 Laptop Keyboard

Bacteria and chemical pollutants are filtered out.

When the restoration of the Sistine Chapel was announced, it sparked a barrage of queries and objections from art historians from around the world. One of the most vocal of these critics was James Beck, of ArtWatch International, who issued repeated warnings about the possibility of damage to Michelangelo's work from over-strenuous restoration. SONY VAIO VGN-SZ750N/C Laptop Keyboard

An argument that was used repeatedly was that all the previous interventions had caused damage of one sort or another. Any restoration, as opposed to conservation, puts an artwork at risk. Conservation, on the other hand, aids in the preservation of the work in its present state and in prevention of further deterioration. Beck has written about his concerns in Art Restoration, the Culture, the Business and the Scandal. Lenovo 45N2106 Laptop Keyboard

In the rhetoric of this conversation, [the conservators] say that the previous restoration was no good – now we're going to make a really good one. It's like having a facelift. How many times can people go through one without their poor faces looking like an orange peel?

While James Beck became "embroiled in a public debate" with Gianluigi Colalucci, SAMSUNG R522 laptop keyboard

Ronald Feldman, a New York art dealer, started a petition supported by 15 well-known artists including Robert Motherwell, George Segal, Robert Rauschenberg, Christo and Andy Warholasking Pope John Paul II to call a halt to the procedure and also the restoration of Leonardo da Vinci's Last Supper.[14]  Lenovo 45N2141 laptop keyboard

An undertaking of the restoration team was that everything would be handled in a transparent fashion, that reporters, art historians and others with a bona fide interest should have ready access to information and to view the work. However, a single company, Nippon Television Network Corporation, had sole photography rights. HP Pavilion dv6-2133ee laptop keyboard

Michael Kimmelman, chief art critic of The New York Times, wrote, in 1991, that the criticism of the restoration of the ceiling and lunettes was in part fuelled by the Nippon Television Network's reluctance to make public those photographs that they had taken by exclusive right, which had recorded every stage of the process and which were the only solid evidence that the work was being done appropriately. HP COMPAQ NX6320 laptop keyboard

According to Kimmelman, the reason for their reluctance to produce the detailed photos, which could have put to rest the worst fears of many of the interested parties, was the intention of the company to produce a large limited-edition two-volume coffee-table book ("as large as a coffee table"). This book, when produced retailed for US$1,000. Kimmelman refers to the fact that these photos were only made available to the few who could afford the exorbitant price as "ungenerous" and "immoral".[15] ASUS X85S laptop keyboard

As the work was progressively completed, there were those who were delighted; Pope John Paul II spoke an inaugural homily after each stage. In December 1999, after the completion of the wall frescoes, he said:It would be difficult to find a more eloquent visual commentary on this biblical image than the Sistine Chapel, whose full splendour we can enjoy today thanks to the recently completed restoration. SONY VAIO VGN-N31Z/W laptop keyboard

Our joy is shared by the faithful throughout the world, who not only cherish this place because of the masterpieces it contains, but also for the role it plays in the Church's life.

—Pope John Paul II, [9]

Cardinal Edmund Szoka, governor of Vatican City, said: "This restoration and the expertise of the restorers allows us to contemplate the paintings as if we had been given the chance of being present when they were first shown."[16]

ASUS X53S laptop keyboard

Other writers were less flattering. Andrew Wordsworth of The Independent, London, expressed the major point of concern:There seems little doubt that the ceiling of the Sistine Chapel was in part painted a secco (that is, once the plaster was dry), but the restorers none the less decided that radical cleaning was necessary, given the amount of dirt that had accumulated (in particular from candle smoke).  LENOVO AEQA1STU010 laptop keyboard

As a result the ceiling now has a curiously washed-out look, with pretty but flavourless colouring – an effect quite unlike that of Michelangelo's intensely sensual sculpture.

—Andrew Wordsworth, [17]

This crucial matter was also emphasised by Beck and defined in very clearly expressed terms on the website of the artist, Peter Layne Arguimbau.  Lenovo 3000 G530 4151 laptop keyboard

That part of the restoration in the Sistine Chapel which has caused the most concern is the ceiling, painted by Michelangelo. The emergence of the brightly colouredAncestors of Christ from the gloom sparked a reaction of fear that the processes being employed in the cleaning were too severe. Despite warnings, the work on the ceiling proceeded and, according to critics such as James Beck, their worst fears were confirmed once the ceiling was completed.[ COMPAQ Presario CQ40-133TU laptop keyboard

The cause for dissent lies in the analysis and understanding of the techniques utilised by Michelangelo, and the technical response of the restorers to their understanding of those techniques. A close examination of the frescoes of the lunettes convinced the restorers that Michelangelo worked exclusively in "buon fresco"; that is, the artist worked only on freshly laid plaster and each section of work was completed while the plaster was still in its fresh state. Lenovo 3000 Y500 laptop keyboard

In other words, Michelangelo did not work "a secco"; he did not come back later and add details onto the dry plaster.

The restorers, by assuming that the artist took a universal approach to the painting, took a universal approach to the restoration. A decision was made that all of the shadowy layer of animal glue and "lamp black", all of the wax, and all of the overpainted areas were contamination of one sort or another: smoke deposits, HP Mini 110-3519la laptop keyboard

earlier restoration attempts and painted definition by later restorers in attempt to enliven the appearance of the work. Based on this decision, according to Arguimbau's critical reading of the restoration data that has been provided, the chemists of the restoration team decided upon a solvent that would effectively strip the ceiling down to its paint-impregnated plaster. After treatment, only that which was painted "buon fresco" would remain. HP COMPAQ 486654-001 laptop keyboard

According to critics, the inherent problem with this approach is that it relied heavily upon an assumption that Michelangelo only painted buon fresco, that he was always satisfied with the result at the end of the day, and that in four and a half years spent on the ceiling, he stuck exclusively to one approach, and never made small alterations or added details. TOSHIBA Satellite L755-S5357 laptop keyboard

Arguimbau, on his website, quotes Colalucci, the head of the team, as contradicting himself on this matter.

A summary of the relevant statements of Colalucci, in the order that they occur in the Appendix entitled Michelangelo's colours uncovered is as follows:The elderly restorers who had taken part in the restoration of the 1930s were interviewed as part of the preparatory process. SONY N860-7676-T101 laptop keyboard

They claimed that Michelangelo worked over the frescoes a secco using velature or glazes as a binder. Colalucci rejects this, stating that Michelangelo worked exclusively in buon fresco. Colalucci then contradicts this by stating that Michelangelo had worked a secco, but "to a minimal degree" and "not at all in the lunettes".

DELL E141395 laptop keyboard

Colalucci then talks of Michelangelo's "rigorous maintenance" of buon fresco technique, contradicting this by describing the a secco retouchings that Michelangelo made to the shoulder of Eleazar and the foot of Reboam, both of which are in the lunettes. He then says that Michelangelo worked in buon fresco with "no pentimenti proper", (pentimenti means the changes) but only small corrections in fresco.[4] HP 518965-001 laptop keyboard

The on-going criticism has been that the restorers presumed to know what end result the master was seeking to achieve in every separate case across the ceiling, and by what method he sought to achieve it. The disagreements about this have been vociferous and are unresolved.

The restorers took for granted that all of the layers of grease and soot on the ceiling were the result of candle smoke. Lenovo ThinkPad Edge E520 laptop keyboard

Contrary to this view, James Beck and numerous artists have suggested that Michelangelo used carbon black in a wash of glue to lay on shadows and crisp dark definition, a secco. If this is the case, then the greater part was removed in the restoration.[21]

On some of the figures, however, there still remains clear evidence of painting in carbon black. LENOVO IdeaPad S10 20015 laptop keyboard

The apparent explanation for this is that over the long period that Michelangelo was at work, he probably, for a variety of reasons, varied his technique. Things that might affect the degree of finish achieved on a particulargiornata include the heat and humidity of the day and the length of daylight hours. Whatever the reason for the difference is, a difference in approach to the light and shade on the individual figures is clearly apparent. HP Pavilion DV7-3078nr laptop keyboard

There are still intense areas of shadow which throw the Cumaean Sibyl into relief. But it is more than relief; it is the three-dimensionality which art-lovers expect to see in the work of the man who sculpted Moses.[19] Critics of the restoration claim that this was Michelangelo's aim and that many frescoes had brightly contrasting colours laid side-by-side that were then worked over a secco to achieve this effect and that this is what has been lost by a too-scrupulous cleaning.[18] Toshiba Satellite L550-20W CPU Fan

Consistently missing from the restored ceiling is the crisp a secco detailing of the architecture: the scallop shells, acorns and "bead and reel" ornament which Michelangelo possibly would have left for completion by an assistant, when he moved on to the next panel. The treatment of these details varied considerably. In a few places, around the Ezekias spandrel, for example, the architectural detailing was painted buon fresco and remains intact. SONY Vaio VPC-EB3E1R/BQ CPU Fan

A comparison of two spandrels reveals different post-restoration states. The one on the left has shadows and details defined in black. The green robe with yellow highlights has been washed with black and defined with deep shadow. On the fictive architecture each motif is picked out in black. The eyes of the child are detailed in black and white. The continued presence of these details suggests that they were completed while the plaster was damp. Dell Precision M4500 CPU Fan

The entire right spandrel has an unfinished look. Before cleaning it also had black defining the shadows of the robes and crisp detailing on the architecture.

On the corner pendentives, each of which depicts a violent subject, the removal of the carbon black has diminished the dramatic intensity of all four scenes. HP G71-340US CPU Fan

This is particularly noticeable in the loss of depth in the Punishment of Haman. Where once the figure projected starkly against the darkly shadowed interior, now foreshortening, definition and drama is lost in the pastel monotone that remains.

The curator, Fabrizio Mancinelli, quotes the 18th-century French traveller De Lalande in saying that the colouring of the ceiling was, Toshiba Satellite L675D-S7016 CPU Fan

by that time, monotonous, "tend[ing] towards dull red and grey". Mancinelli writes that the restoration reveals "a new Michelangelo" as a colourist and that this "new character makes much better sense of his historical position".[7] He goes on to say that perceptive viewers of the Sistine Chapel ceiling have always been aware that the range of colours used was very different from that which could be seen,[7] HP Pavilion dv5-2135dx CPU Fan

and included the same pinks, apple greens, oranges, yellows and pale blues that were employed by Michelangelo's teacher, Domenico Ghirlandaio, one of the most competent fresco painters of the Renaissance.

The brilliant palette ought to have been expected by the restorers as the same range of colours appears in the works of Giotto, Masaccio and Masolino, HP Envy 17-3000er CPU Fan

Fra Angelicoand Piero della Francesca, as well as Ghirlandaio himself and later fresco painters such as Annibale Carracci and Tiepolo. The reason for employing this range of colours is that many other pigments are not usable in fresco as they have chemical properties that react badly in interaction with wet plaster. The colour that is noticeably missing from Michelangelo's ceiling, but not The Last Judgment, is the intense blue of lapis lazuli.  HP Envy 17 Series CPU Fan

This colour, achieved by grinding semi-precious stone, was always applied as a secondary, a secco stage, along with the gold leaf applied as haloes and decoration to robes.

The aspect of the colouring which was most unexpected was Michelangelo's treatment of shadows. The painting of theLibyan Sibyl and the Prophet Daniel, which are side-by-side, are exemplary. HP 532614-001 CPU Fan

On the yellow dress of the Sibyl, Michelangelo has bright yellow highlights, passing through carefully graded tones of deeper yellow to pale orange, darker orange and almost to red in the shadows. While red shadows are of themselves unusual in a fresco, the gradation through adjacent parts of the spectrum is a natural enough solution. On Daniel's robes, there is no such gentle gradation. HP Envy 17-3000er CPU Fan

The yellow lining of his cloak becomes a sudden dense green in the shadows, while the mauve has shadows that are intensely red. These colour combinations, which are best described as iridescent, can be found at various places on the ceiling, including the hose of the young man in the Mathan lunette which is pale green and reddish purple. HP 532614-001 CPU Fan

In some instances, the colour combinations look garish: this is particularly the case with the Prophet Daniel. A comparison of the "restored" and "unrestored" figure gives strong evidence that Michelangelo worked over this figure in a wash of carbon black, and that the technique was preplanned.[22] The bright red used on the robes of Daniel and the Libyan Sibyl does not, on its own, create effective shadows. HP 532614-001 CPU Fan

In these and many other cases it appears to have been intended as underpainting, to be seen only through a thin black wash and with the deepest shadows picked out in more intense black, as they still are on the Cumaean Sibyl. This use of bright, contrasting colours as underpainting is not a common feature of frescoes, but it is commonly employed in both oil painting and tempera.  HP KSB06105HA CPU Fan

Like Daniel, the Libyan Sibyl's yellow garment once had much more subtlety in its folds and shadows than it has now.

There is absolutely no doubt that before the restoration, the whole ceiling was dirtier, more muted and more monochrome than Michelangelo ever intended, but when images of the frescoes are viewed in their stained and unrestored state the subtle washes and intense definitions, HP 493001-001 CPU Fan

described by Beck and Arguimbau,[18][19] still make their presence known, giving mass and bulk to the forms.

The painter and biographer Giorgio Vasari, in his Lives of the Artists, describes the figure of Jonah as it appeared in the mid-16th century:"Then who is not filled with admiration and amazement at the awesome sight of Jonah, the last figure in the chapel?Toshiba BFB0605HA CPU Fan

The vaulting naturally springs forward, following the curve of the masonry; but through the force of art it is apparently straightened out by the figure of Jonah, which bends in the opposite direction; and thus vanquished by the art of design, with its lights and shades, the ceiling even appears to recede."[23]

The large figure of Jonah is of great significance to the total composition, both pictorially and theologically, being symbolic of the Risen Christ. HP Pavilion dv5-1174ca CPU Fan

The figure occupies the pendentive which rises from the altar wall to support the vault, and strains backward, his eyes turned towards God. The foreshortening described by Vasari was innovative and highly influential to later painters. The cleaning of this significant figure has left a few remnants of black shadow visible to the extreme left side of the painting. Toshiba Satellite A110-101 CPU Fan

All the other, less intense, black lines and washes have been removed, lessening the impact of the radical foreshortening, and also robbing the great fish, the genii behind Jonah, and the architectural figures of much detail.

The missing depth is not the only factor that the critics deplore. An important feature of Michelangelo's work which, in many places, has disappeared forever is the painting of the eyeballs.[24] HP Pavilion dv5-1174ca CPU Fan

Eyes appear in many instances to have been painted buon fresco. Wherever they have not been painted buon fresco but added a secco, they have been removed by the restorers.[24]

They are an essential part of the most impressive and famous of the frescoes, the Creation of Adam. Adam gazes at God. God looks directly at Adam. And under God's protective arm, Eve turns her eyes sideways in a look of admiration for her husband-to-be. HP 535442-001 CPU Fan

Again and again, Michelangelo painted telling gazes into the faces of his characters. The eye sockets of the family in the Zorobabel lunette are empty as are the eyes of the man in the Aminadab lunette, but the removal that has caused the most distress to the critics are the eyes of the little figure in green and white who once looked out of the gloom above the lunette of Jesse. HP Pavilion dv6-3049tx CPU Fan

Arguimbau says:Have you ever felt that some things never fade and remain an inspiration for all time? That was the Sistine Chapel, now chemically stripped down of divine inspiration and looking shockingly out of place. ...It is the duty of the restorer not to alter the intent of the artist, but the scientist cannot help himself. Who cares if Colalucci discovered Michelangelo as a colorist and can explain the Colorist trends of Pontormo and Rossi. ACER Aspire 5730Z Series CPU Fan

His job is to make sure the thing is stuck on there and leave it alone. In comparing before and after photos there is much proof that Colalucci removed ‘a secco' passages and left many areas sketchy and thin and. [sic] Proof of one single change of the artist's intent is negligence of which there are many.

Carlo Pietrangeli, former Director General of the Vatican Museums, writes of the restoration:  HP KSB06105HA CPU Fan

"It is like opening a window in a dark room and seeing it flooded with light."[6] His words resonate with those of Giorgio Vasari who, in the 16th century, said of the Sistine Chapel ceiling:There is no other work to compare with this for excellence ... The ceiling has proved a veritable beacon for our art, of inestimable benefit to all painters, restoring light to a world that for centuries had been plunged into darkness.[23] HP Pavilion dv5-2135dx CPU Fan

Pietrangeli, in his foreword to The Sistine Chapel, written after the restoration of the lunettes, but prior to the restoration of the ceiling, commends those who had the courage to commence the restoration process, and thanks not only those who visited the restoration while it was in progress and gave the benefit of their knowledge and experience, but also those who were critical of the enterprise. Toshiba Satellite L650-1MT CPU Fan

Pietrangeli made acknowledgement that these people spurred the team on to punctilious documentation so that a full report of criteria and methods should be available to those who are interested, both in the present and the future.

Pope Sixtus IV (Latin: Xystus IV; 21 July 1414 – 12 August 1484), born Francesco della Rovere, was Pope from 9 August 1471 to his death in 1484. SONY Vaio VGN-NW350F CPU Fan

His accomplishments as pope included building the Sistine Chapel; the group of artists that he brought together introduced the Early Renaissance into Rome with the first masterpieces of the city's new artistic age. He also established the Vatican Archives. Sixtus furthered the agenda of the Spanish Inquisition and annulled the decrees of the Council of Constance. Toshiba Satellite M35X-S329 CPU Fan

He was famed for his nepotism and was personally involved in the infamous Pazzi Conspiracy.Francesco was born to a family of modest means from Liguria, Italy, the son of Leonardo della Rovere and Luchina Monleoni. He was born in Celle Ligure, a town near Savona.As a young man Della Rovere joined the Franciscan Order, an unlikely choice for a political career, and his intellectual qualities were revealed while he was studying philosophy and theology at the University of Pavia. SONY Vaio VGN-TX2XP/B CPU Fan

He went on to lecture at Padua and many other Italian universities.[3]

In 1464, Della Rovere was elected Minister General of the Franciscan order at the age of 50. In 1467, he was appointedCardinal by Pope Paul II with the titular church being the Basilica of San Pietro in Vincoli. Before his papal election, LENOVO IdeaPad S10 20015 Laptop Keyboard

Cardinal della Rovere was renowned for his unworldliness and had even written learned treatises entitled On the Blood of Christ and On the Power of God.[4] His pious reputation was one of the deciding factors that prompted the College of Cardinals to elect him pope upon the unexpected death of Paul II at the age of fifty-four.

Upon being elected pope Della Rovere adopted the name Sixtus – a name that had not been used since the 5th century. FUJITSU Lifebook S7110 Laptop Keyboard

One of his first acts was to declare a renewed crusade against the Ottoman Turks in Smyrna. However, after the conquest of Smyrna, the fleet disbanded.[6] Some fruitless attempts were made towards unification with the Greek Church. For the remainder of his pontificate, Sixtus turned to temporal issues and dynastic considerations.

Sixtus IV sought to strengthen his position by surrounding himself with relatives and friends.  DELL Vostro 3550 Laptop Keyboard

In the fresco by Melozzo da Forlì he is accompanied by his Della Rovere and Riarionephews, not all of whom were made cardinals: the protonotary apostolic Pietro Riario (on his right), the future Pope Julius II standing before him, and Girolamo Riario and Giovanni della Rovere behind the kneeling Platina, author of the first humanist history of the Popes.[7] His nephew Pietro Riario also benefited from his nepotism. TOSHIBA PK130260100 Laptop Keyboard

Pietro became one of the richest men in Rome and was entrusted with Pope Sixtus' foreign policy. However, Pietro died prematurely in 1474, and his role passed to Giuliano della Rovere.

The secular fortunes of the Della Rovere family began when Sixtus invested his nephew Giovanni with the lordship of Senigallia and arranged his marriage to the daughter of Federico III da Montefeltro, duke of Urbino; Lenovo 45N2205 Laptop Keyboard

from this union came a line of Della Rovere dukes of Urbino that lasted until the line expired in 1631.[8] Six of the thirty-four cardinals that he created were his nephews.[9]

In his territorial aggrandizement of the Papal States, Sixtus' niece's son Cardinal Raffaele Riario, for whom the Palazzo della Cancelleria was constructed, HP 636376-001 Laptop Keyboard

was a leader in the failed "Pazzi conspiracy" of 1478 to assassinate both Lorenzo de' Medici and his brother Giuliano and replace them in Florence with Sixtus IV's other nephew, Girolamo Riario. Francesco Salviati, Archbishop of Pisa and a main organizer of the plot, was hanged on the walls of the Florentine Palazzo della Signoria. To this, Sixtus IV replied with an interdict and two years' of war with Florence. HP Pavilion dv6-2112sa Laptop Keyboard

According to the later published chronicle of the Italian historian Stefano Infessura, "Diary of the City of Rome", Sixtus was a "lover of boys and sodomites" - awarding benefices and bishoprics in return for sexual favours, and nominating a number of young men as cardinals; some of whom were celebrated for their good look.HP 517865-031 Laptop Keyboard

However, Infessura had partisan allegiances to the Colonna and so is not considered to be always reliable or impartial.[13] The English churchman and protestant polemicist John Bale writing a century later, attributed to Sixtus "the authorisation to practice sodomy during periods of warm weather" to the "Cardinal of Santa Lucia".[14] However, such accusations are easily dismissed as anti-Catholic propaganda,[10] HP Compaq NC8430 Laptop Keyboard

but did nevertheless prompt the noted historian of the Catholic Church, Ludwig von Pastor, to issue a firm rebuttal.

Sixtus continued a dispute with King Louis XI of France, who upheld the Pragmatic Sanction of Bourges (1438), according to which papal decrees needed royal assent before they could be promulgated in France.[3] This was a cornerstone of the privileges claimed for the Gallican Church, SAMSUNG NP-N102-JA01DX Laptop Keyboard

and could never be shifted as long as Louis XI maneuvered to replace King Ferdinand I of Naples with a French prince. Louis was thus in conflict with the papacy and Sixtus could not permit it.

On 1 November 1478, Sixtus published the papal bull Exigit Sincerae Devotionis Affectus, through which the Spanish Inquisition was established in the Kingdom of Castile. DELL V119525BS1 Laptop Keyboard

Sixtus consented under political pressure from Ferdinand of Aragon, who threatened to withhold military support from his kingdom of Sicily.[citation needed]Nevertheless, Sixtus IV quarrelled over protocol and prerogatives of jurisdiction, was unhappy with the excesses of the Inquisition and condemned the most flagrant abuses in 1482.[16]

As a temporal prince who constructed stout fortresses in the Papal States, he encouraged the Venetians to attack Ferrara, which he wished to obtain for another nephew. TOSHIBA Satellite P500 Laptop Keyboard

Ercole I d'Este, Duke of Ferrara, was allied with the Sforzas of Milan, the Medicis of Florence along with the King of Naples, normally a hereditary ally and champion of the papacy. The angered Italian princes allied to force Sixtus IV to make peace, to his great annoyance.[3] For refusing to desist from the very hostilities that he himself had instigated (and for being a dangerous rival to Della Rovere dynastic ambitions in the Marche),  Lenovo ThinkPad Edge E520 Laptop Keyboard

Sixtus placed Venice under interdictin 1483. He also lined the coffers of the state by unscrupulously selling high offices and privileges.[6]In ecclesiastical affairs, Sixtus promoted the cult of the Immaculate Conception, which had been confirmed at the Council of Basle in 1439[6] and designated 8 December as the Feast day of the Immaculate Conception of Mary. He formally annulled the decrees of the Council of Constance in 1478. TOSHIBA Satellite L300 Laptop Keyboard

The two papal bulls issued by Pope Nicholas V, Dum Diversas of 1452 and Romanus Pontifex of 1455, had effectively given the Portuguese the rights to acquire slaves along the African coast by force or trade. These concessions were confirmed by Sixtus in his own bull, Aeterni regis of 21 June 1481.[17] Arguably the "ideology of conquest" expounded in these texts became the means by which commerce and conversion were facilitated.[18] DELL AEFM8U00310 Laptop Keyboard

In November 1476 Isabel and Fernando ordered an investigation into rights of conquest in the Canary Islands, and in the spring of 1478 they sent Juan Rejon with sixty soldiers and thirty cavalry to the Grand Canary, where the natives retreated inland. Sixtus' earlier threats to excommunicate all captains or pirates who enslaved Christians in the   DELL 0P445M Laptop Keyboard

bull Regimini Gregis of 1476 could have been intended to emphasise the need to convert the natives of the Canary Islands and Guinea and establish a clear difference in status between those who had converted and those who resisted.[19] The ecclesiastical penalties were directed towards those who were enslaving the recent converts.  TOSHIBA Mini NB 255-SP1002L Laptop Keyboard

As a civic patron in Rome, even the anti-papal chronicler Stefano Infessura agreed that Sixtus should be admired. The dedicatory inscription in the fresco by Melozzo da Forlì in the Vatican Palace records: "You gave your city temples, streets, squares, fortifications, bridges and restored the Acqua Vergine as far as the Trevi..." SONY Vaio VGN-SZ73B/B CPU Fan

In addition to restoring the aqueduct that provided Rome an alternative to the river water that had made the city famously unhealthy, he restored or rebuilt over 30 of Rome's dilapidated churches, among them San Vitale (1475) and Santa Maria del Popolo, and added seven new ones. The Sistine Chapel was sponsored by Sixtus IV, as was the Ponte Sisto,[7] Dell Latitude E6510 CPU Fan

the Sistine Bridge – the first new bridge across the Tiber since antiquity – and the building of Via Sistina (later named Borgo Sant'Angelo), a road leading from Castel Sant'Angelo to Saint Peter. All this was done to facilitate the integration of the Vatican Hill and Borgo with the heart of old Rome. This was part of a broader scheme of urbanization carried out under Sixtus IV, SONY UDQFRZH13CF0 CPU Fan

who swept the long-established markets from the Campidoglio in 1477 and decreed in a bull of 1480 the widening of streets and the first post-Roman paving, the removal of porticoes and other post-classical impediments to free public passage.

At the beginning of his papacy in 1471, HP Pavilion dv6-3370ca CPU Fan

Sixtus donated several historically important Roman sculptures that founded a papal collection of art that would eventually develop into the collections of theCapitoline Museums. He also re-founded, enriched and enlarged the Vatican Library.[7] He hadRegiomontanus attempt the first sanctioned reorganization of the Julian calendar and increased the size and prestige of the papal chapel choir, HP G62-341NR CPU Fan

bringing singers and some prominent composers (Gaspar van Weerbeke, Marbrianus de Orto, and Bertrandus Vaqueras) to Rome from the North.In addition to being a patron of the arts, Sixtus was a patron of the sciences. Before becoming pope, he spent time at the then very liberal and cosmopolitan University of Padua, which maintained considerable independence from the Church and had a very international characterHP 535438-001 CPU Fan

. As Pope, he issued a papal bull allowing local bishops to give the bodies of executed criminals and unidentified corpses to physicians and artists for dissection. It was this access to corpses which allowed the anatomist Vesalius, along with Titian's pupil Jan Stephen van Calcar, to complete the revolutionary medical/anatomical text De humani corporis fabricaDell Vostro 3450 CPU Fan

Pope Sixtus' tomb was destroyed in the Sack of Rome in 1527. Today, his remains, along with the remains of his nephew Pope Julius II (Giuliano della Rovere), are interred in St. Peter's Basilica in the floor in front of the monument to Pope Clement X. A simple marble tombstone marks the site.

His bronze funerary monument, now in the basement Treasury of St. Peter's Basilica, DELL XPS M170 CPU Fan

like a giant casket of goldsmith's work, is byAntonio Pollaiuolo. The top of the casket is a lifelike depiction of the Pope lying in state. Around the sides are bas relief panels, depicting with allegorical female figures the arts and sciences (Grammar, Rhetoric, Arithmetic, Geometry, Music, Painting, Astronomy, Philosophy, and Theology). SONY Vaio VGN-SZ2XP/C CPU Fan

Each figure incorporates the oak tree ("rovere" in Italian) symbol of Sixtus IV. The overall program of these panels, their beauty, complex symbolism, classical references, and arrangement relative to each other is on
