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 :. | St John in the Wilderness | Madonna with the Yarnwinder (detail) dft | Portrait of a Musician dey | Knieened figure in Draperie | Our Lady and St Anne |

Jan Weenix
Dutch Baroque Era Painter , Amsterdam 1640/42-1719 Painter and draughtsman, son of (1) Jan Baptist Weenix. Jan probably received his first instruction as a painter from his father, and it is possible that he helped finish certain of his father's works. He probably remained in Utrecht after his father's death. By 1664 he had become a member of the Guild of St Luke in Utrecht without, however, having submitted the required entrance painting, which he provided by 1668. There are several documented references to Jan in the late 1660s. He inherited a legacy along with his uncle, the painter Barent Micker, and other family members in 1667, at which time Gillis, his younger brother, apparently still required a guardian. He received another legacy in 1668, the year of his marriage, and in 1669 served as a witness for the inventory of the painter Jacob de Hennin (1629-c. 1688) in The Hague.

Edward Matthew Ward
British Painter. 1816-1879 His parents encouraged his early interest in art. He was sent to a number of art schools, including that of John Cawse (1779-1862), before gaining entry to the Royal Academy Schools in 1835. He first exhibited at the Royal Academy in 1834 with Adelphi Smith as Don Quixote (untraced). In 1836 he went abroad for further study, visiting Paris and Venice on the way to Rome, where he spent three years. His first work of any consequence was Cimabue and Giotto (untraced), which he sent back to the Royal Academy show of 1839. On the way back to England at the end of that year Ward visited Munich to learn the technique of modern fresco painting in order to take part in the competition to decorate the Palace of Westminster, but his cartoon, Boadicea (1843; untraced), was unsuccessful. However, in 1852 he was commissioned to produce eight pictures for the Palace of Westminster, on subjects drawn from the English Civil War, the best of which is the Last Sleep of Argyll (1860s) in the Commons Corridor of the Houses of Parliament
