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 :. | Anatomical studies of the basin of the Steibeins and the lower Gliedmaben of a woman and study of the rotation of the arms | Study fur the Sforza monument | Portrait | The Virgin and Child with St Anne (detail) f | Madonna with a Flower |

BREKELENKAM, Quiringh van
Dutch painter (active c. 1647-1669 in Leiden) Dutch painter. He probably trained in Leiden, possibly under Gerrit Dou. In 1648, with several other painters, he founded the Guild of St Luke in Leiden. He married for the first time in 1648 and again in 1656, a year after his first wife's death. In 1649 his sister Aeltge married the painter Johannes Oudenrogge (1622-53), and the couple soon moved to Haarlem while the Brekelenkam family remained in Leiden. About 1656 Brekelenkam apparently acquired a licence to sell beer and brandy, perhaps because his income as a painter was insufficient to support his large family (six children from his first marriage and three from his second). He continued to be active as an artist and paid his guild dues fairly regularly. The last dues were paid in 1667, and his last dated painting, the Portrait of a Man Aged 33, is from 1669.
Fernand cormon
French Academic Painter, 1845-1924 French painter. He studied initially in Brussels under Jean-Fran?ois Portaels. In 1863 he returned to Paris, where for three years he was a pupil of Alexandre Cabanel and Eug?ne Fromentin. He made his d?but at the Salon in 1868 and in 1870 received a medal for the Marriage of the Niebelungen (1870; ex-Mus. B.-A., Lisieux, 1970). His painting the Death of King Ravana (1875; Toulouse, Mus. Augustins), taken from the Indian epic poem the Ramayana, was criticized for the choice of an obscure subject but was nevertheless awarded the Prix de Salon in 1875. Soon afterwards Cormon left France for Tunisia. After his return in 1877 he exhibited regularly at the Salon until his death, establishing a reputation as a painter of historical and religious subjects; he also produced some portraits.
