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 :. | Leda and the Swan | Maria with Child and St. Anna | Portrat of a musician | Study of the proportion of horses | Annunciation |

Isaac Cruikshank
English Illustrator, ca.1756-1811 Scottish painter and caricaturist, was born in Edinburgh. His sons Isaac Robert Cruikshank (1789-1856) and George Cruikshank also became artists, and the latter in particular achieved fame as an illustrator and caricaturist. Cruikshank is known for his social and political satire. His parents were Elizabeth Davidson (b. c.1725), daughter of a gardener, and Andrew Crookshanks (c.1725 Cc.1783), a former customs inspector dispossessed for his role in the Jacobite uprising of 1745. He studied with a local artist, possible John Kay (1742 C1826), and travelled with his master to London in 1783. He married Mary MacNaughton (1769 C1853) in 1788 and the couple had five known children, two of whom died in infancy. A daughter, Margaret Eliza, also a promising artist, died at the age of eighteen. Cruikshank's first known publications were etchings of Edinburgh "types", from 1784. He produced illustrations for books about the theatre, did the frontispiece for Witticisms and Jests of Dr Johnson (1791), and illustrated George Shaw's extensive General Zoology (1800 C26). His watercolours were exhibited, but in order to make a living it was more lucritive to produce prints and caricatures. He was responsive to the marketplace but firm in his dislikes of Napoleon and political radicals. He and Gillray developed the figure of John Bull, the nationalistic representation of a solid British yeoman. Publisher John Roach was a friend and patron, and he later worked with print dealer S. W. Fores and Johnny Fairburn. He also collaborated, with G. M. Woodward, and later, with his son George. Cruikshank died of alcohol poisoning at the age of fifty-five as a result of a drinking contest and is buried near his home in London.
