Mona Lisa (Hermitage)
Hermitage Mona Lisa is a painting on canvas, which was made by an unknown painter in the mid-16th century and is located in the Hermitage Museum of Saint Peterburg. It was transferred from the ''Antikvariat All-Union Association'' and entered the Hermitage in 1931. Description This portrait is an image of Lisa Gherardini, best known as ''Mona Lisa'' or ''Gioconda'', and is a clear copy of the original Gioconda. Although it is notably different from the authentic Mona Lisa of the Louvre in Paris, the good workmanship, legibility and expressiveness emanating from the work have been pointed out. The execution of the portrait is presumably of Nordic Europe derivation, in particular German-Flemish. The face of the model is different, being younger than the version of Leonardo da Vinci, but also the rear panorama presents two columns, which are absent in the original. Many people call this picture ''Gioconda with columns''. Two columns are found in other copies such as ''Gioconda of Osl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lisa Gherardini
Lisa del Giocondo (; ; June 15, 1479 – July 15, 1542) was an Italian noblewoman and member of the Gherardini family of Florence and Tuscany. Her name was given to the ''Mona Lisa'', her portrait commissioned by her husband and painted by Leonardo da Vinci during the Italian Renaissance. Little is known about Lisa's life. Born in Florence and married in her teens to a cloth and silk merchant and shoemaker who later became a local official, she was a mother to five children and led what is thought to have been a comfortable and ordinary middle-class life. Lisa outlived her husband, who was considerably her senior. In the centuries after Lisa's death, the ''Mona Lisa'' became the world's most famous painting. In 2005, Lisa was definitively identified as the model for the ''Mona Lisa''. Early life and family Lisa's Florentine family was old and aristocratic but over time had lost their influence. They were well off but not wealthy, and lived on farm income in a city that w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walters Art Museum
The Walters Art Museum, located in Mount Vernon-Belvedere, Baltimore, Maryland, United States, is a public art museum founded and opened in 1934. It holds collections established during the mid-19th century. The museum's collection was amassed substantially by major American art and sculpture collectors, a father and son: William Thompson Walters, (1819–1894), who began collecting when he moved to Paris as a nominal Southern/Confederate sympathizer at the outbreak of the American Civil War in 1861; and Henry Walters (1848–1931), who refined the collection and made arrangements for the construction of a later landmark building to rehouse it. After allowing the Baltimore public to occasionally view his father's and his growing added collections at his West Mount Vernon Place townhouse/mansion during the late 1800s, he arranged for an elaborate stone palazzo-styled structure built for that purpose in 1905–1909. Located across the back alley, a block south of the Walters mansio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gioconda Torlonia
''La Gioconda'' is an opera in four acts by Amilcare Ponchielli set to an Italian libretto by Arrigo Boito (as Tobia Gorrio), based on ''Angelo, Tyrant of Padua'', a 1835 play in prose by Victor Hugo (the same source Gaetano Rossi had used for his libretto for Mercadante's '' Il giuramento'' in 1837). First performed in 1876, ''La Gioconda'' was a major success for Ponchielli, as well as the most successful new Italian opera between Verdi's '' Aida'' (1871) and ''Otello'' (1887). It is also a famous example of the Italian genre of ''Grande opera'', the equivalent of French '' Grand-Opéra''. Ponchielli revised the work twice; the third and final version (that is used to this day) was first performed in 1880. There are several complete recordings of the opera, and it is regularly performed, especially in Italy. It is one of only a few operas that features a principal role for each of the six major voice types. The opera also includes the famous ballet '' Dance of the Hours'', o ...

Isleworth Mona Lisa
The ''Isleworth Mona Lisa'' is an early sixteenth-century oil on canvas painting depicting the same subject as Leonardo da Vinci's ''Mona Lisa'', though with the subject ( Lisa del Giocondo) depicted as being a younger age. The painting is thought to have been brought from Italy to England in the 1780s, and came into public view in 1913 when the English connoisseur Hugh Blaker acquired it from a manor house in Somerset, where it was thought to have been hanging for over a century. The painting would eventually adopt its unofficial name of ''Isleworth Mona Lisa'' from Blaker's studio being in Isleworth, West London. Since the 1910s, experts in various fields, as well as the collectors who have acquired ownership of the painting, have asserted that the major elements of the painting are the work of Leonardo himself, as an earlier version of the ''Mona Lisa''. In 1914, art critic Paul George Konody criticized early reports of the painting, which contained errors that he believed c ...

Mona Lisa (Prado)
The Prado ''Mona Lisa'' is a painting by the workshop of Leonardo da Vinci and depicts the same subject and composition as Leonardo's better known ''Mona Lisa'' at the Louvre, Paris. The Prado ''Mona Lisa'' has been in the collection of the Museo del Prado in Madrid, Spain since 1819, but was considered for decades a relatively unimportant copy. Following its restoration in 2012, however, the Prado's ''Mona Lisa'' has come to be understood as the earliest known studio copy of Leonardo's masterpiece. Although there are dozens of surviving copies of the ''Mona Lisa'' from the 16th and 17th centuries, the Prado's ''Mona Lisa'' may have been painted simultaneously by a student of Leonardo in the same studio where he painted his own ''Mona Lisa'', so it is said to be the copy with the most historical value. Among the pupils of Leonardo, Salaì or Francesco Melzi are the most plausible authors of the Prado's version, though other experts argue that the painting could have been exe ...

Chemistry
Chemistry is the science, scientific study of the properties and behavior of matter. It is a natural science that covers the Chemical element, elements that make up matter to the chemical compound, compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a Chemical reaction, reaction with other Chemical substance, substances. Chemistry also addresses the nature of chemical bonds in chemical compounds. In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both Basic research, basic and Applied science, applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant growth (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the properties ...

Barium Sulphate
Barium sulfate (or sulphate) is the inorganic compound with the chemical formula Ba SO4. It is a white crystalline solid that is odorless and insoluble in water. It occurs as the mineral barite, which is the main commercial source of barium and materials prepared from it. The white opaque appearance and its high density are exploited in its main applications.Holleman, A. F. and Wiberg, E. (2001) ''Inorganic Chemistry'', San Diego, CA : Academic Press, . Uses Drilling fluids About 80% of the world's barium sulfate production, mostly purified mineral, is consumed as a component of oil well drilling fluid. It increases the density of the fluid, increasing the hydrostatic pressure in the well and reducing the chance of a blowout. Radiocontrast agent Barium sulfate in suspension is often used medically as a radiocontrast agent for X-ray imaging and other diagnostic procedures. It is most often used in imaging of the GI tract during what is colloquially known as a "barium meal" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baryte
Baryte, barite or barytes ( or ) is a mineral consisting of barium sulfate ( Ba S O4). Baryte is generally white or colorless, and is the main source of the element barium. The ''baryte group'' consists of baryte, celestine (strontium sulfate), anglesite (lead sulfate), and anhydrite (calcium sulfate). Baryte and celestine form a solid solution (Ba,Sr)SO4. Names and history The radiating form, sometimes referred to as ''Bologna Stone'', attained some notoriety among alchemists for specimens found in the 17th century near Bologna by Vincenzo Casciarolo. These became phosphorescent upon being calcined. Carl Scheele determined that baryte contained a new element in 1774, but could not isolate barium, only barium oxide. Johan Gottlieb Gahn also isolated barium oxide two years later in similar studies. Barium was first isolated by electrolysis of molten barium salts in 1808 by Sir Humphry Davy in England.

Dulwich Picture Gallery
Dulwich Picture Gallery is an art gallery in Dulwich, South London, which opened to the public in 1817. It was designed by Regency architect Sir John Soane using an innovative and influential method of illumination. Dulwich is the oldest public art gallery in England and was made an independent charitable trust in 1994. Until this time the gallery was part of the College of God's Gift, a charitable foundation established by the actor, entrepreneur, and philanthropist Edward Alleyn in the early 17th century. The acquisition of artworks by its founders and bequests from its many patrons resulted in Dulwich Picture Gallery housing one of the country's finest collections of Old Masters, especially rich in French, Italian, and Spanish Baroque paintings, and in British portraits from Tudor times to the 19th century. The Dulwich Picture Gallery and its mausoleum are listed Grade II* on the National Heritage List for England. History Early history of the gallery Edward Alleyn (1566 ...

Oil Painting
Oil painting is the process of painting with pigments with a medium of drying oil as the binder. It has been the most common technique for artistic painting on wood panel or canvas for several centuries, spreading from Europe to the rest of the world. The advantages of oil for painting images include "greater flexibility, richer and denser colour, the use of layers, and a wider range from light to dark". But the process is slower, especially when one layer of paint needs to be allowed to dry before another is applied. The oldest known oil paintings were created by Buddhist artists in Afghanistan and date back to the 7th century AD. The technique of binding pigments in oil was later brought to Europe in the 15th century, about 900 years later. The adoption of oil paint by Europeans began with Early Netherlandish painting in Northern Europe, and by the height of the Renaissance, oil painting techniques had almost completely replaced the use of tempera paints in the majority ...
