Lucan Portrait
The Lucan portrait of Leonardo da Vinci is a late 15th- or early 16th-century portrait of a man that was discovered in 2008 in a cupboard of a private house in Italy. It strongly resembles a portrait of Leonardo da Vinci by Cristofano dell'Altissimo held by the Uffizi Gallery. The painting was previously thought by its owners to represent Galileo but on its discovery a claim was made that it is a self-portrait by Leonardo da Vinci.Richard Owen, Portrait of Leonardo da Vinci discovered in Basilicata', The Times, 2009-02-24, accessed 5 November 2010 Alessandro Vezzosi, director of the Museo Ideale Leonardo da Vinci at Vinci said in 2011 that he had excluded the possibility that it was a self-portrait, but that the painting "remains intriguing because it adds a new element to the Leonardo puzzle". Painted in tempera grassa on panel, , it depicts a man in three-quarter view, with a long beard and wearing a dark hat. In 2019 it is being exhibited in Madrid along with other materia ...

Tempera
Tempera (), also known as egg tempera, is a permanent, fast-drying painting medium consisting of colored pigments mixed with a water-soluble binder medium, usually glutinous material such as egg yolk. Tempera also refers to the paintings done in this medium. Tempera paintings are very long-lasting, and examples from the first century AD still exist. Egg tempera was a primary method of painting until after 1500 when it was superseded by oil painting. A paint consisting of pigment and binder commonly used in the United States as poster paint is also often referred to as "tempera paint", although the binders in this paint are different from traditional tempera paint. Etymology The term ''tempera'' is derived from the Italian ''dipingere a tempera'' ("paint in distemper"), from the Late Latin ''distemperare'' ("mix thoroughly"). History Tempera painting has been found on early Egyptian sarcophagus decorations. Many of the Fayum mummy portraits use tempera, sometimes in combina ...

Mitre Joint
A mitre joint (often miter in American English) is a joint made by cutting each of two parts to be joined, across the main surface, usually at a 45° angle, to form a corner, usually to form a 90° angle, though it can comprise any angle greater than 0 degrees. It is called beveling when the angled cut is done on the side, although the resulting joint is still a mitre joint. For woodworking, a disadvantage of a mitre joint is its Strength of materials, weakness, but it can be strengthened with a spline (a thin wafer of wood inserted into a slot, usually arranged with the long grain of the spline across the short grain of the frame timber). There are two common variations of a splined mitre joint, one where the spline is long and runs the length of the mating surfaces and another where the spline is perpendicular to the joined edges. Common applications include picture frames, Pipe (fluid conveyance), pipes, and moulding (decorative), molding. Non-perpendicular joints For mitr ...

Carbon 14 Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for Chronological dating, determining the age of an object containing organic material by using the properties of carbon-14, radiocarbon, a radioactive Isotopes of carbon, isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Atmosphere of Earth, Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Craquelure
Craquelure (french: craquelé; it, crettatura) is a fine pattern of dense cracking formed on the surface of materials. It can be a result of drying, aging, intentional patterning, or a combination of all three. The term is most often used to refer to tempera or oil paintings, but it can also develop in old ivory carvings or painted miniatures on an ivory backing. Recently, analysis of craquelure has been proposed as a way to authenticate art. In ceramics, craquelure in ceramic glazes, where it is often a desired effect, is called "crackle"; it is a characteristic of Chinese Ge ware in particular. This is usually differentiated from crazing, which is a glaze defect in firing, or the result of aging or damage. In painted surfaces Painting systems are composed of complex layers with unique mechanical properties that depend on the type of drying oil or paint medium used and the presence of paint additives, such as organic solvents, surfactants, and plasticizers.

Giovio Series
The Giovio Series, also known as the Giovio Collection or Giovio Portraits, is a series of 484 portraits assembled by the 16th-century Italian Renaissance historian and biographer Paolo Giovio. It includes portraits of literary figures, rulers, statesmen and other dignitaries, many of which were done from life. Intended by Giovio as a public archive of famous men, the collection was originally housed in a specially-built museum on the shore of Lake Como. Although the original collection has not survived intact, a set of copies made for Cosimo I de' Medici now has a permanent home in Florence's Uffizi Gallery. Origins and history Giovio first began collecting portraits around 1512, soon after leaving his hometown of Como to pursue his career in Rome.

The series included illustrious men of ages past alongside those of his own day. Giovio intend ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cosimo I De' Medici, Grand Duke Of Tuscany
Cosimo I de' Medici (12 June 1519 – 21 April 1574) was the second Duke of Florence from 1537 until 1569, when he became the first Grand Duke of Tuscany, a title he held until his death. Life Rise to power Cosimo was born in Florence on 12 June 1519, the son of the famous condottiere Ludovico de' Medici (known as Giovanni delle Bande Nere) and his wife Maria Salviati, herself a granddaughter of Lorenzo the Magnificent. He was the grandson of Caterina Sforza, the Countess of Forlì and Lady of Imola. Cosimo came to power in 1537 at age 17, just after the 26-year-old Duke of Florence, Alessandro de' Medici, was assassinated. Cosimo was from a different branch of the Medici family, descended from Giovanni il Popolano, the great-grandson of Giovanni di Bicci de' Medici, founder of the Medici Bank. It was necessary to search for a successor outside of the "senior" branch of the Medici family descended from Cosimo di Giovanni de' Medici, since the only male child of Alessandro, ...

Overpainting
Overpainting is the final layers of paint, over some type of underpainting, in a system of working in layers. It can also refer to later paint added by restorers, or an artist or dealer wishing to "improve" or update an old image—a very common practice in the past. The underpainting gives a context in which the paint-strokes of the overpainting become more resonant and powerful. When properly done, overpainting does not need to completely obscure the underpainting. It is precisely the interaction of the two that gives the most interesting effects. Overpainting was used extensively in many schools of art. Some of the most spectacular results can be seen in the work of Jan van Eyck. It can be difficult to distinguish overpainting from underpainting in finished historical artworks in the absence of scientific tests. X-rays An X-ray, or, much less commonly, X-radiation, is a penetrating form of high-energy electromagnetic radiation. Most X-rays have a wavelength ranging from 1 ...
