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 :. | Madonna with the Yarnwinder ty | The Last Supper | Madonna in the rock grottos(Details | The Baptism of Christ (detail) sg | Portrait de femme,dit a tort La belle ferronniere |

Frans de Momper
Flemish Baroque Era Painter, 1603-1660 Painter and draughtsman, nephew of (1) Josse de Momper II. In 1629 he became a master in the Antwerp Guild of St Luke. He left Antwerp for the northern Netherlands, working initially at The Hague; by 1647 he was in Haarlem and the following year Amsterdam, where he married in 1649. In 1650 Frans returned to Antwerp, where he painted numerous monochrome landscapes in the manner of Jan van Goyen. Paintings such as the Valley with Mountains (c. 1640-50; Philadelphia, PA, Mus. A.) prefigure the imaginative landscapes of Hercules Segers. The impression of vast panoramic spaces in Frans's work is adopted from his uncle's art. Frans executed a number of variations on the theme of a river landscape with boats and village (e.g. pen-and-ink drawing, Edinburgh, N.G.). In the late painting Landscape with a Ch?teau Encircled by Doves (Bordeaux, Mus. B.-A.), the low horizon and light-filled sky are adopted from the new Dutch school of tonal landscape painting, while the delicacy of the figures, feathery trees and buildings are features of the Italo-Flemish tradition exemplified by his uncle. Similar qualities of refinement and luminosity characterize the Winter Landscape (c. 1650; Prague, N.G., Sternberk Pal.),
Henri Decaisne
a Belgian historical and portrait painter, was born at Brussels in 1799. As early as 1814 he began to study painting under François, and in 1818 upon the advice of David he went to Paris and entered the studio of Girodet, whence he removed to that of Gros. Several pictures by him are at Versailles; among them are the 'Entry of Charles VII into Rouen' (1838), and the 'Institution of the Order of St. John of Jerusalem' (1842). In 1839 he completed his colossal work, ' Les Belges Illustres.' He died in Paris in 1852. Among his best works are:
Thomas Baines
(27 November 1820 ?C 8 May 1875) was an English artist and explorer of British colonial southern Africa and Australia. Born in King's Lynn, Norfolk, Baines was apprenticed to a coach painter at an early age. When he was 22 he left England for South Africa aboard the "Olivia" (captained by a family friend William Roome) and worked for a while in Cape Town as a scenic and portrait artist, and as official war artist during the so-called Eighth Frontier War for the British Army. In 1855 Baines joined Augustus Gregory??s 1855?C1857 Royal Geographical Society sponsored expedition across northern Australia as official artist and storekeeper. The expedition??s purpose was to explore the Victoria River district in the north-west and to evaluate the entire northern area of Australia in terms of its suitability for colonial settlement.
