Restoration Of The Sistine Chapel Frescoes
The conservation-restoration of the frescoes of the Sistine Chapel was one of the most significant conservation-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. 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. 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. The tapestries on the lowest tier, today best known from the Raphael Cartoons (painted designs) of 1515–16, completed the ensemble. Together the paintings make up the greatest pictorial scheme of the Renaissance. Individually, some of Michelangelo's paintings on th ...

Michelangelo Buonarroti 018
Michelangelo di Lodovico Buonarroti Simoni (; 6 March 1475 – 18 February 1564), known as Michelangelo (), was an Italian sculptor, painter, architect, and poet of the High Renaissance. Born in the Republic of Florence, his work was inspired by models from classical antiquity and had a lasting influence on Western art. Michelangelo's creative abilities and mastery in a range of artistic arenas define him as an archetypal Renaissance man, along with his rival and elder contemporary, Leonardo da Vinci. Given the sheer volume of surviving correspondence, sketches, and reminiscences, Michelangelo is one of the best-documented artists of the 16th century. He was lauded by contemporary biographers as the most accomplished artist of his era. Michelangelo achieved fame early; two of his best-known works, the ''Pietà (Michelangelo), Pietà'' and ''David (Michelangelo), David'', were sculpted before the age of thirty. Although he did not consider himself a painter, Michelangelo cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Creation Of Adam
'' Creation of Adam'' () is a fresco painting by Italian artist Michelangelo, which forms part of the Sistine Chapel's ceiling, painted c. 1508–1512. It illustrates the Biblical creation narrative from the Book of Genesis in which God gives life to Adam, the first man. The fresco is part of a complex iconographic scheme and is chronologically the fourth in the series of panels depicting episodes from Genesis. The painting has been reproduced in countless imitations and parodies. Michelangelo's ''Creation of Adam'' is one of the most replicated religious paintings of all time. History In 1505, Michelangelo was invited back to Rome by the newly elected Pope Julius II. He was commissioned to build the Pope's tomb, which was to include forty statues and be finished in five years. Under the patronage of the Pope, Michelangelo experienced constant interruptions to his work on the tomb in order to accomplish numerous other tasks. Although Michelangelo worked on the tomb for 40 ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Walnut Oil
Walnut oil is oil extracted from walnuts, ''Juglans regia''. The oil contains polyunsaturated fatty acids, monounsaturated fatty acids, and saturated fats. Composition Walnut oil is composed largely of polyunsaturated fatty acids (72% of total fats), particularly alpha-linolenic acid (14%) and linoleic acid (58%), oleic acid (13%), and saturated fats (9%). Culinary use Walnut oil is edible and is generally used less than other oils in food preparation, often due to high pricing. It is light-coloured and delicate in flavour and scent, with a nutty quality. Although chefs sometimes use walnut oil for pan-frying, most avoid walnut oil for high-temperature cooking because heating tends to reduce the oil's flavour and produce a slight bitterness. Walnut oil is preferred in cold dishes such as salad dressings. Cold-pressed walnut oil is typically more expensive due to the loss of a higher percentage of the oil. Refined walnut oil is expeller-pressed and saturated with solvent to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linseed Oil
Linseed oil, also known as flaxseed oil or flax oil (in its edible form), is a colourless to yellowish oil obtained from the dried, ripened seeds of the flax plant (''Linum usitatissimum''). The oil is obtained by pressing, sometimes followed by solvent extraction. Owing to its polymer-forming properties, linseed oil is often blended with combinations of other oils, resins or solvents as an impregnator, drying oil finish or varnish in wood finishing, as a pigment binder in oil paints, as a plasticizer and hardener in putty, and in the manufacture of linoleum. Linseed oil use has declined over the past several decades with increased availability of synthetic alkyd resins—which function similarly but resist yellowing. Linseed oil is an edible oil in demand as a dietary supplement, as a source of α-Linolenic acid, an omega-3 fatty acid. In parts of Europe, it is traditionally eaten with potatoes and quark.

Gianluigi Colalucci
Gianluigi Colalucci (24 December 1929 – 28 March 2021) was an Italian Master Restorer and academic most known for being the chief restorer of the Sistine Chapel in the Vatican City from 1980 to 1994. Career Colalucci graduated in the restoration of painting on wood, mural, and canvas, from the in 1953, where he was a pupil of Cesare Brandi. Colalucci began working with the Vatican in 1960, and between 1980 and 1994 led the restoration of the Sistine Chapel frescoes, directing a team of twelve, and removing centuries of smoke, dust, glue, varnishes, and wine which had dulled the frescoes, as well as allowing art historians to visit the chapel during this work and observe the team's restoration technique. He initially faced opposition, with art historian James Beck describing the restoration as an "artistic Chernobyl", and with prominent artists including Andy Warhol, Robert Motherwell, George Segal, Robert Rauschenberg petitioning Pope John Paul II to pause the work; Colal ...

Efflorescence
In chemistry, efflorescence (which means "to flower out" in French) is the migration of a salt to the surface of a porous material, where it forms a coating. The essential process involves the dissolving of an internally held salt in water, or occasionally in another solvent. The water, with the salt now held in solution, migrates to the surface, then evaporates, leaving a coating of the salt. In what has been described as "primary efflorescence", the water is the invader and the salt was already present internally, and a reverse process, where the salt is originally present externally and is then carried inside in solution, is referred to as "secondary efflorescence". Efflorescences can occur in natural and built environments. On porous construction materials it may present a cosmetic outer problem only (primary efflorescence causing staining), but can sometimes indicate internal structural weakness (migration/degradation of component materials). Efflorescence may clog the po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potassium Nitrate
Potassium nitrate is a chemical compound with the chemical formula . This alkali metal nitrate salt is also known as Indian saltpetre (large deposits of which were historically mined in India). It is an ionic salt of potassium ions K+ and nitrate ions NO3−, and is therefore an alkali metal nitrate. It occurs in nature as a mineral, niter (or ''nitre'' in the UK). It is a source of nitrogen, and nitrogen was named after niter. Potassium nitrate is one of several nitrogen-containing compounds collectively referred to as saltpeter (or ''saltpetre'' in the UK). Major uses of potassium nitrate are in fertilizers, tree stump removal, rocket propellants and fireworks. It is one of the major constituents of gunpowder (black powder). In processed meats, potassium nitrate reacts with hemoglobin and myoglobin generating a red color. Etymology Potassium nitrate, because of its early and global use and production, has many names. Hebrew and Egyptian words for it had the consonants n-t-r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paolo Giovio
Paolo Giovio (also spelled ''Paulo Jovio''; Latin: ''Paulus Jovius''; 19 April 1483 – 11 December 1552) was an Italian physician, historian, biographer, and prelate. Early life Little is known about Giovio's youth. He was a native of Como; his family was from the Isola Comacina of Lake Como. His father, a notary, died around 1500. He was educated under the direction of his elder brother Benedetto, a humanist and historian. Although interested in literature, he was sent to Padua to study medicine. He graduated in 1511.

ArtWatch International
ArtWatch International is an American nonprofit organization founded by James Beck, professor of art history at Columbia University, to monitor, and campaign for better practices in, the conservation of art works. The United Kingdom branch, ArtWatch UK, is run by Michael Daley. Activities In 1991, Beck criticised the cleaning of Jacopo della Quercia's sculpture, the tomb of Ilaria del Carretto in Lucca cathedral in Italy. As a result, the conservator sued him for "aggravated slander", which carries a possible three-year prison sentence. Beck won the case and subsequently co-founded ArtWatch."In Memoriam", ''The Art Newspaper'', July/August 2007. ArtWatch has been critical of many conservation practices and projects, including the restoration of Leonardo da Vinci's ''The Last Supper'' and the restoration of the Sistine Chapel frescoes. In 2004, it raised an unsuccessful petition to halt the restoration of Michelangelo's ''David'', which has since been found to be developing cr ...

The Globe And Mail
''The Globe and Mail'' is a Canadian newspaper printed in five cities in western and central Canada. With a weekly readership of approximately 2 million in 2015, it is Canada's most widely read newspaper on weekdays and Saturdays, although it falls slightly behind the ''Toronto Star'' in overall weekly circulation because the ''Star'' publishes a Sunday edition, whereas the ''Globe'' does not. ''The Globe and Mail'' is regarded by some as Canada's " newspaper of record". ''The Globe and Mail''s predecessors, '' The Globe'' and ''The Mail and Empire'' were both established in the 19th century. The former was established in 1844, while the latter was established in 1895 through a merger of ''The Toronto Mail'' and the ''Toronto Empire''. In 1936, ''The Globe'' and ''The Mail and Empire'' merged to form ''The Globe and Mail''. The newspaper was acquired by FP Publications in 1965, who later sold the paper to the Thomson Corporation in 1980. In 2001, the paper merged with broadcast ...
