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 :. | A rock gorge | The Annunciation | The Anunciacion | Anatomy of the Schadels | Annunciation (detail) dfe |

hendrik averkamp
Hendrick Avercamp (bapt. January 27, 1585, Amsterdam - buried May 15, 1634, Kampen (Overijssel)) was a Dutch painter. Avercamp studied in Amsterdam with the Danish-born portrait painter Pieter Isaacks (1569-1625), and perhaps also with David Vinckbooms. In 1608 he moved from Amsterdam to Kampen in the province of Overijssel. Avercamp was mute and was known as "de Stomme van Kampen" (the mute of Kampen). As one of the first landscape painters of the 17th-century Dutch school, he specialized in painting the Netherlands in winter. Avercamp's paintings are colorful and lively, with carefully crafted images of the people in the landscape. Many of Avercamp's paintings feature people ice skating on frozen lakes. Avercamp's work enjoyed great popularity and he sold his drawings, many of which were tinted with water-color, as finished pictures to be pasted into the albums of collectors. The Royal Collection has an outstanding collection of his works. Avercamp died in Kampen and was interred there in the Sint Nicolaaskerk.
Wilhelm von Schadow
German Romantic Painter, 1788-1862,Painter, teacher and writer, son of Johann Gottfried Schadow. He studied at the Berlin Akademie from 1805 and in 1806 showed paintings at the annual Akademie exhibition. Under his teacher, Friedrich Georg Weitsch, he quickly became a skilled portrait painter, and by 1810 he was commissioned to paint portraits of members of the Prussian royal family and of the Empress of Austria. Influenced by the English artist John Flaxman, Schadow developed an emphasis on outline. In 1810 Schadow went with his brother Ridolfo Schadow to Rome, where in 1813 he became a member of the Lukasbreder and, in 1814, a Catholic. In 1815-17 he took part, with Peter von Cornelius, Friedrich Overbeck and Philipp Veit, in the commission for frescoes of the Story of Joseph for a room in the Casa Bartholdy (now Berlin, Alte N.G.). In his continuing interest in portraits, Schadow differed from his colleagues. Following the example of Gottlieb Schick and similarly inspired by Raphael, Schadow developed a poetic style of portraiture. In 1819 he returned to Berlin in order to help Karl Friedrich Schinkel with the decoration of the Schauspielhaus. He took over the running of a studio and won a high degree of respect as a painter and teacher.
