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 :. | Mona Lisa (La Gioconda) sdg | Buste one frontal to seeing man and head of a Lowen | Raffaello Sanzio named Raffael Portrat of Lorenzo de Medici | The Virgin and Child with St Anne (detail) f | St John the Baptist t |

Cornelis Bega
1632-1664 Dutch Cornelis Bega Galleries Dutch painter, draughtsman and etcher. He was born into prosperous circumstances; his mother, Maria Cornelis, inherited half the estate (gold, silver, paintings, drawings and prints) and all of the red chalk drawings of her father, Cornelis Cornelisz. van Haarlem, a renowned Mannerist artist. Begas father was Pieter Jansz. Begijn (d 1648), a gold- and silversmith. Like other family members, Bega was probably Catholic. Houbrakens claim that Bega studied with Adriaen van Ostade is likely to be correct; this was probably before 24 April 1653, when Bega joined Vincent Laurentsz. van der Vinne in Frankfurt for a journey through Germany, Switzerland and France. Bega had returned to Haarlem by 1 September 1654, at which time he joined the Guild of St Luke; he was already a competent draughtsman, as indicated by his first extant dated work, Interior with a Nursing Mother (1652; Frankfurt am Main, Stedel. Kstinst.), and by a remarkable double portrait (Amsterdam, Rijksmus.) drawn by him and Leendert van der Cooghen in 1654.

Thomas Hickey
was an Irish painter. Born in Dublin, Hickey was the son of Noah, a confectioner in Capel Street, and Anne Hickey. A younger brother was John Hickey, the sculptor. He was trained at the Royal Dublin Society schools under Robert West. Hickey painted primarily portraits and genre scenes. He traveled widely, working in India, Portugal, Italy and England, residing in Bath between 1776 and 1780. On his voyage to India, the vessel in which he was travelling was captured by French and Spanish fleets which led him to Lisbon, where, after receiving a number of commissions, he remained for several years. He eventually reached Bengal and stayed there until 1791 when he returned to England. He then traveled as far as Peking, China with George Macartney, 1st Earl Macartney as the expedition's official portrait painter. He returned to Ireland shortly after the death of his brother John in January 1796. In 1797, he was commissioned by Dr. Robert Emmet, State Physician for Ireland, to paint a portrait of the doctor's son, Robert, and daughter, Mary. By 1798 he had returned to India where he landed just in time for the start of the Fourth Mysore War, which kept him engaged in painting. He resided in Madras until his death in 1824. In addition to his artistic talents, he is reputed to have been a sparkling conversationalist who rarely failed to charm his sitters. The Courtauld Institute of Art (London), the Honolulu Academy of Arts, the National Gallery of Ireland, the Tate and the Victoria Art Gallery (Bath, England) are among the public collections having paintings by Thomas Hickey.
