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 :. | Power and ortraits | Aurelio Luini attributed, profile of an old man | Funf studies of grotesque faces | Mona Lisa | Self Portrait |

BOSSCHAERT, Ambrosius the Elder
Dutch Baroque Era Painter, 1573-1621 Painter and dealer. He left Antwerp with his parents c. 1587 because as Protestants they were vulnerable to religious persecution; the family moved to Middelburg, where in 1593 Ambrosius became a member of the Guild of St Luke, of which he served as Dean on several occasions (1597, 1598, 1603, 1604, 1612 and 1613). In 1604 he married Maria van der Ast, the sister of Balthasar van der Ast who later became his pupil and possible collaborator. Bosschaert bought a house in Middelburg in 1611. There are flower-pieces by Bosschaert that are signed (with a monogram) and dated between 1605 and 1621, though there were two periods of artistic inactivity, in 1611-13 and 1615-16, when he was probably more active as a dealer in the art of both Dutch and foreign artists (e.g. Veronese and Georg Flegel). He was recorded in Bergen-op-Zoom in 1615 and became a citizen of Utrecht in 1616, where his name appears in the register of the Utrecht Guild of St Luke for the same year. In 1619 he was involved in a court case in Breda, where he lived from that year. He died during a journey to The Hague.
