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 :. | The Virgin and Child with St Anne (detail) f | The Last Supper sgu | The Virgin and St Anne | Anatomical drawing of the stomach and the intestine | Anatomical study of the brain and the scalp |

Francis Hayman
English Painter, 1708-1776,English painter and illustrator. He was in London at the age of 10, and from 1718 until c. 1725 he was apprenticed to Robert Brown (d 1753), a decorative painter. From 1732 Hayman was employed as a scene painter at Goodman's Fields Theatre, where he painted allegorical works such as The King Attended by Peace, with Liberty and Justice Trampling on Tyranny and Oppression on the pit ceiling (destr.). He moved to Drury Lane Theatre in 1736, shortly before the Licensing Act closed Goodman's Fields. At Drury Lane he painted scenery for Thomas Arne's masque The Fall of Phaeton (1736) and was praised for his naturalistic landscapes. From the late 1730s he began accepting commissions for portraits and conversation pieces. His success in the field of portraiture rested on the dearth of good portrait painters in England at the time and his exploitation of a growing middle-class clientele. Hayman painted portraits of doctors, literary men and actors.

After six years of study in Milwaukee, Denny returned to San Francisco and established a studio on Bush Street. In 1862, Brooks moved to San Francisco and shared a studio with Denny. In 1868, Denny spent two months in Hawaii visiting several islands. He is also known to have visited Canada and South America. Denny died of malaria in Cambria, California on Oct. 7, 1886.
