Lapis-lazuli
Lapis lazuli (; ), or lapis for short, is a deep-blue metamorphic rock used as a semi-precious stone that has been prized since antiquity for its intense color. Originating from the Persian word for the gem, ''lāžward'', lapis lazuli is a rock composed primarily of the minerals lazurite, pyrite and calcite. As early as the 7th millennium BC, lapis lazuli was mined in the Sar-i Sang mines,David Bomford and Ashok Roy, ''A Closer Look- Colour'' (2009), National Gallery Company, London, () in Shortugai, and in other mines in Badakhshan province in modern northeast Afghanistan. Lapis lazuli artifacts, dated to 7570 BC, have been found at Bhirrana, which is the oldest site of Indus Valley civilisation. Lapis was highly valued by the Indus Valley Civilisation (3300–1900 BC). Lapis beads have been found at Neolithic burials in Mehrgarh, the Caucasus, and as far away as Mauritania. It was used in the funeral mask of Tutankhamun (1341–1323 BC).

Pyrite
The mineral pyrite ( ), or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula Fe S2 (iron (II) disulfide). Pyrite is the most abundant sulfide mineral. Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of ''fool's gold''. The color has also led to the nicknames ''brass'', ''brazzle'', and ''brazil'', primarily used to refer to pyrite found in coal. The name ''pyrite'' is derived from the Greek (), 'stone or mineral which strikes fire', in turn from (), 'fire'. In ancient Roman times, this name was applied to several types of stone that would create sparks when struck against steel; Pliny the Elder described one of them as being brassy, almost certainly a reference to what is now called pyrite. By Georgius Agricola's time, , the term had become a generic term for all of the sulfide minerals. Pyrite is usually found associated with other sulfides or oxides in ...

Caucasus
The Caucasus () or Caucasia (), is a region spanning Eastern Europe and Western Asia. It is situated between the Black Sea and the Caspian Sea, comprising parts of Southern Russia, Georgia, Armenia, and Azerbaijan.

Dental Tartar
In dentistry, calculus or tartar is a form of hardened dental plaque. It is caused by precipitation of minerals from saliva and gingival crevicular fluid (GCF) in plaque on the teeth. This process of precipitation kills the bacterial cells within dental plaque, but the rough and hardened surface that is formed provides an ideal surface for further plaque formation. This leads to calculus buildup, which compromises the health of the gingiva (gums). Calculus can form both along the gumline, where it is referred to as supragingival (), and within the narrow sulcus that exists between the teeth and the gingiva, where it is referred to as subgingival (). Calculus formation is associated with a number of clinical manifestations, including bad breath, receding gums and chronically inflamed gingiva. Brushing and flossing can remove plaque from which calculus forms; however, once formed, calculus is too hard (firmly attached) to be removed with a toothbrush. Calculus buildup can be r ...

Vermeer
Johannes Vermeer ( , ; see below; also known as Jan Vermeer; October 1632 – 15 December 1675) was a Dutch painter who specialized in domestic interior scenes of middle-class life. He is considered one of the greatest painters of the Dutch Golden Age. During his lifetime, he was a moderately successful provincial genre painter, recognized in Delft and The Hague. He produced relatively few paintings, primarily earning his living as an art dealer. He was not wealthy; at his death, his wife was left in debt. Vermeer worked slowly and with great care, and frequently used very expensive pigments. He is particularly renowned for making masterful use of light in his work. "Almost all his paintings", Hans Koningsberger wrote, "are apparently set in two smallish rooms in his house in Delft; they show the same furniture and decorations in various arrangements and they often portray the same people, mostly women." The modest celebrity he enjoyed during his life gave way to obscuri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Perugino
Pietro Perugino ( ; ; born Pietro Vannucci or Pietro Vanucci; – 1523), an Italian Renaissance painter of the Umbrian school, developed some of the qualities that found classic expression in the High Renaissance. Raphael became his most famous pupil. Early years Pietro Vannucci was born in Città della Pieve, Umbria, the son of Cristoforo Maria Vannucci. His nickname characterizes him as from Perugia, the chief city of Umbria. Scholars continue to dispute the socioeconomic status of the Vannucci family. While certain academics maintain that Vannucci worked his way out of poverty, others argue that his family was among the wealthiest in the town.

Masaccio
Masaccio (, ; ; December 21, 1401 – summer 1428), born Tommaso di Ser Giovanni di Simone, was a Florentine artist who is regarded as the first great List of Italian painters, Italian painter of the Quattrocento period of the Italian Renaissance. According to Giorgio Vasari, Vasari, Masaccio was the best painter of his generation because of his skill at imitating nature, recreating lifelike figures and movements as well as a convincing sense of three-dimensionality. He employed nudes and foreshortenings in his figures. This had seldom been done before him.Vasari, Giorgio, "The Lives of the Artists" Translated by Julia Conaway Bondanella and Peter Bondanella, Oxford World Classics. The name Masaccio is a humorous version of Maso (short for Tommaso), meaning "clumsy" or "messy" Tom. The name may have been created to distinguish him from his principal collaborator, also called Maso, who came to be known as Masolino ("little/delicate Tom"). Despite his brief career, he had a pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ultramarine
Ultramarine is a deep blue pigment which was originally made by grinding lapis lazuli into a powder. Its lengthy grinding and washing process makes the natural pigment quite valuable—roughly ten times more expensive than the stone it comes from and as expensive as gold. The name ultramarine comes from the Latin word . The word means 'beyond the sea', as the pigment was imported by Italian traders during the 14th and 15th centuries from mines in Afghanistan. Much of the expansion of ultramarine can be attributed to Venice which historically was the port of entry for lapis lazuli in Europe. Ultramarine was the finest and most expensive blue used by Renaissance painters. It was often used for the robes of the Virgin Mary and symbolized holiness and humility. It remained an extremely expensive pigment until a synthetic ultramarine was invented in 1826. Ultramarine is a permanent pigment when under ideal preservation conditions. Otherwise, it is susceptible to discoloration a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
