Italian High Renaissance Painter and Inventor, 1452-1519 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 :. | Hl.

Pieter de Hooch
1629-1684 Dutch Pieter de Hooch Galleries De Hooch was born in Rotterdam to Hendrick Hendricksz de Hooch, a bricklayer, and Annetge Pieters, a midwife. He was the eldest of five children and outlived all of his siblings. He studied art in Haarlem under the landscape painter, Nicolaes Berchem. Beginning in 1650, he worked as a painter and servant for a linen-merchant and art collector named Justus de la Grange. His service for the merchant required him to accompany him on his travels to The Hague, Leiden, and Delft, to which he eventually moved. It is likely that de Hooch handed over most of his works to la Grange during this period in exchange for board and other benefits, as this was a common commercial arrangement for painters at the time, and a later inventory recorded that la Grange possessed eleven of his paintings. De Hooch was married in Delft in 1654 to Jannetje van der Burch, by whom he fathered seven children. While in Delft, de Hooch is also believed to have learned from the painters Carel Fabritius and Nicolaes Maes, who were both early members of the Delft School. He became a member of the painters' guild of Saint Luke in 1655, and had moved to Amsterdam by 1661. The early work of de Hooch, like most young painters of his time, was mostly composed of scenes of soldiers in stables and taverns, though he used these to develop great skill in light, color, and perspective rather than to explore an interest in the subject matter. After beginning his family in the mid-1650s, he switched his focus to domestic scenes and family portraits. His work showed astute observation of the mundane details of everyday life while also functioning as well-ordered morality tales. These paintings often exhibited a sophisticated and delicate treatment of light similar to those of Vermeer, who lived in Delft at the same time as de Hooch. 19th century art historians had assumed that Vermeer had been influenced by de Hooch's work, but the opposite is now believed.
ZUCCARO Federico
Italian Mannerist Painter, ca.1542-1609 ..Painter, draughtsman and writer, brother of (1) Taddeo Zuccaro. Having been invited to Rome by his brother, between 1555 and 1563 he worked with Taddeo on various projects including the Villa Farnese at Caprarola and the Pucci Chapel in Trinit? dei Monti, Rome. Many of Federico's drawings for both commissions show Taddeo's influence. According to Vasari, Taddeo supervised his brother's early work, which created friction between them. In 1558, for example, when they collaborated on painting the fa?ade of the house of Tizio da Spoleto with scenes from the Life of St Eustace, Taddeo retouched some of his brother's paintings, so offending Federico. Already at 18 Federico was commissioned to paint many works at the Vatican: the Transfiguration, the Marriage at Cana and other scenes from the Life of Christ for the decorations (part destr.) of the Casino of Pius IV;
