Italian High Renaissance Painter and Inventor, 1452-1519 Florentine Renaissance man, genius, artist in all media, architect, military engineer. Possibly the most brilliantly creative man in European history, he advertised himself, first of all, as a military engineer. In a famous letter dated about 1481 to Ludovico Sforza, of which a copy survives in the Codice Atlantico in Milan, Leonardo asks for employment in that capacity. He had plans for bridges, very light and strong, and plans for destroying those of the enemy. He knew how to cut off water to besieged fortifications, and how to construct bridges, mantlets, scaling ladders, and other instruments. He designed cannon, very convenient and easy of transport, designed to fire small stones, almost in the manner of hail??grape- or case-shot (see ammunition, artillery). He offered cannon of very beautiful and useful shapes, quite different from those in common use and, where it is not possible to employ cannon ?? catapults, mangonels and trabocchi and other engines of wonderful efficacy not in general use. And he said he made armoured cars, safe and unassailable, which will enter the serried ranks of the enemy with their artillery ?? and behind them the infantry will be able to follow quite unharmed, and without any opposition. He also offered to design ships which can resist the fire of all the heaviest cannon, and powder and smoke. The large number of surviving drawings and notes on military art show that Leonardo claims were not without foundation, although most date from after the Sforza letter. Most of the drawings, including giant crossbows (see bows), appear to be improvements on existing machines rather than new inventions. One exception is the drawing of a tank dating from 1485-8 now in the British Museum??a flattened cone, propelled from inside by crankshafts, firing guns. Another design in the British Museum, for a machine with scythes revolving in the horizontal plane, dismembering bodies as it goes, is gruesomely fanciful. Most of the other drawings are in the Codice Atlantico in Milan but some are in the Royal Libraries at Windsor and Turin, in Venice, or the Louvre and the École des Beaux Arts in Paris. Two ingenious machines for continuously firing arrows, machine-gun style, powered by a treadmill are shown in the Codice Atlantico. A number of other sketches of bridges, water pumps, and canals could be for military or civil purposes: dual use technology. Leonardo lived at a time when the first artillery fortifications were appearing and the Codice Atlantico contains sketches of ingenious fortifications combining bastions, round towers, and truncated cones. Models constructed from the drawings and photographed in Calvi works reveal forts which would have looked strikingly modern in the 19th century, and might even feature in science fiction films today. On 18 August 1502 Cesare Borgia appointed Leonardo as his Military Engineer General, although no known building by Leonardo exists. Leonardo was also fascinated by flight. Thirteen pages with drawings for man-powered aeroplanes survive and there is one design for a helicoidal helicopter. Leonardo later realized the inadequacy of the power a man could generate and turned his attention to aerofoils. Had his enormous abilities been concentrated on one thing, he might have invented the modern glider.  Related Paintings of Leonardo Da Vinci :. | Bacchus | Saint John the Baptist | Horses with horsemen | Virgin and Child with St Anne and St John the Baptist | Madonna and Child with a Pomegranate |

MASACCIO
Italian Early Renaissance Painter, 1401-1428 was the first great painter of the Quattrocento period of the Italian Renaissance. His frescoes are the earliest monuments of Humanism, and introduce a plasticity previously unseen in figure painting. The name Masaccio is a humorous version of Tommaso, meaning "big", "fat", "clumsy" or "messy" Tom. The name was created to distinguish him from his principal collaborator, also called Tommaso, who came to be known as Masolino ("little/delicate Tom"). Despite his brief career, he had a profound influence on other artists. He was one of the first to use scientific perspective in his painting, employing techniques such as vanishing point in art for the first time. He also moved away from the Gothic style and elaborate ornamentation of artists like Gentile da Fabriano to a more natural mode that employed perspective for greater realism. Masaccio was born to Giovanni di Mone Cassa??i and Jacopa di Martinozzo in Castel San Giovanni di Altura, now San Giovanni Valdarno (now part of the province of Arezzo, Tuscany). His father was a notary and his mother the daughter of an innkeeper of Barberino di Mugello, a town a few miles south of Florence. His family name, Cassai, comes from the trade of his grandfather Simone and granduncle Lorenzo, who were carpenters - cabinet makers ("casse", hence "cassai"). His father died in 1406, when Tommaso was only five; in that year another brother was born, called Giovanni after the dead father. He also was to become a painter, with the nickname of "Scheggia" meaning "splinter". The mother was remarried to an elderly apothecary, Tedesco, who guaranteed Masaccio and his family a comfortable childhood.
Pieter Boel
(1626-1674) was a Flemish Baroque painter who specialised in lavish still lifes. Boel was born in Antwerp. He probably went to Italy in 1650. In 1668, he worked for Charles Le Brun (1619-1690) in his first tapestry making studio. According to Arnold Houbraken, whose source was his picture in Cornelis de Bie's book Het Gulden Cabinet, he specialized in painting animals. He died in Paris.
