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 Refectory with the Last Supper after restoration g | Portrats of two men | The adoration of the Konige | Annunciation sgt66 | Study fur the communion |

Martin Archer Shee
RA (December 23, 1769 - August 13, 1850) was a British portrait painter and president of the Royal Academy. He was born in Dublin, of an old Catholic Irish family, and his father, a merchant, regarded the profession of a painter as an unsuitable occupation for a descendant of the Shees. Martin Shee nevertheless studied art in the Dublin Society, and came to London. There, in 1788, he was introduced by William Burke to Joshua Reynolds, on whose advice he studied in the schools of the Royal Academy. In 1789 he exhibited his first two pictures, the "Head of an Old Man" and "Portrait of a Gentleman." Over the next ten years he steadily increased in practice. He was chosen an associate of the Royal Academy in 1798, in 1789 he married, and in 1800 he was elected a Royal Academician. He moved to George Romney's former house in Cavendish Square, and set up as his successor. Shee continued to paint with great readiness of hand and fertility of invention, although his portraits were eclipsed by more than one of his contemporaries, and especially by Thomas Lawrence. The earlier portraits of the artist are carefully finished, easy in action, with good drawing and excellent discrimination of character. They show an undue tendency to redness in the flesh painting defect which is still more apparent in his later works, in which the handling is less "square," crisp and forcible. In addition to his portraits he executed various subjects and historical works, such as Lavinia, Belisarius, his diploma picture "Prospero and Miranda", and the "Daughter of Jephthah." In 1805 he published a poem consisting of Rhymes on Art, and a second part followed in 1809. Lord Byron spoke well of it in his English Bards and Scotch Reviewers. Shee published another small volume of verse in 1814, entitled The Commemoration of Sir Joshua Reynolds, and other Poems, but this was less successful. He also produced a tragedy, Alasco, set in Poland. The play was accepted at Covent Garden, but was refused a licence, on the grounds that it contained treasonable allusions, and Shee angrily resolved to make his appeal to the public. He carried out his threat in 1824, but Alasco was still on the list of unacted dramas in 1911. He also published two novels - "Oldcourt" (1829, in 3 volumes) and "Cecil Hyde" (1834).
