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 :. | Portrait of Ginevra de Benci | The Annunciation | Head and shoulders Christs | Annunciation (detail) ey79 | The Virgin and the Nino with Holy Ana |

Jan de Bray
1627-1697 Dutch Painter, draughtsman and etcher, son of (1) Salomon de Bray. He spent virtually the whole of his career in Haarlem, except for the period 1686-8, when he lived in Amsterdam. After training with his father, Jan began working as a portrait painter in Haarlem in 1650, an activity he continued for the next 40 years. Between 1667 and 1684 he served on the committee for the Haarlem Guild of St Luke, whose leading members he portrayed in a picture dated 1675 (Amsterdam, Rijksmus.) that includes a self-portrait (Jan is seen standing and drawing on the left). He married three times, in 1668, 1670 and 1672. His first two wives died a year after their marriage, his third two years afterwards, and in each case the death was followed by disputes over the inheritance. Jan bankruptcy of 1689 may have been a result of one of the lawsuits. He was 62 at the time, and from then onwards he seems to have lost his artistic drive, crushed by the financial blow and the consequent loss of social position.
Jan Rustem
(b. 1762 in Istanbul - d. 1835 near Dekštas, Lithuania) was a painter of Armenian, Turkish or Greek ethnicity who lived and worked in the territories of the Polish CLithuanian Commonwealth. Primarily a portrait painter, he was commissioned to execute portraits of notable personalities of his epoch. For many years he was a professor at the University of Vilna, the predecessor of Vilnius University. He was born in Instanbul, and a young boy was sponsored by Adam Kazimierz Czartoryski who invited him to the Commonwealth around 1774. Czartoryski paid for his studies in Warsaw, where among his tutors were Jean-Pierre Norblin de La Gourdaine and Marcello Bacciarelli. Between 1788 and 1790 he moved to Germany, where he became a freemason. Two years later he returned to the Polish?CLithuanian Commonwealth and lived for some time in Warsaw, later moving to Vilna. Following the partitions of the Commonwealth, Rustem started working for the Common School of Vilna, which was later remamed the Imperial University of Vilna, as assistant to Franciszek Smuglewicz. After Smuglewicz's death, Rustem took over some of his duties. In 1811 he became a professor of sketching and in 1819 became a professor of painting. Rustem retired in 1826, but continued to give lectures until his death.
