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 :. | Adoration of the Magi | Christ's Head | The Virgin of the Rocks | Bacchus | John the Baptist |

Jean-Baptiste Paulin Guerin
(March 25, 1783 - January 19, 1855), French painter, was born at Toulon, of poor parents. As a young man, he learned his father's trade of locksmithing, whilst at the same time he followed the classes of the free school of art. Having sold some copies to a local amateur, Guerin started for Paris, where he came under the notice of Vincent, whose counsels were of material service. In 1810 Guerin made his first appearance at the Salon with some portraits, which had a certain success. In 1812 he exhibited "Cain after the murder of Abel" (formerly in Luxembourg), and, on the return of the Bourbons, was much employed in works of restoration and decoration at Versailles.
Alfred Edward Emslie
Alfred Edward Emslie (1848 London -1918) was an English genre and portrait painter, and photographer, living at The Studio, 34, Finchley Road, N. W. He was the son of the engraver, John Emslie, and brother of John Phillipps Emslie, the figure painter. Married to miniature painter Rosalie M. Emslie, they had a daughter, Rosalie Emslie, who became a figure, portrait and landscape painter. Emslie turned increasingly to portraiture later in life. He had a great passion for the Orient, and spent three months exploring Japan. He was a elected an associate of the Royal Society of Painters in Water Colours in 1888 and a member of the Royal Society of Portrait Painters in 1892.
Roger Van Der Weyden
c.1399-1464 Rogier van der Weyden was the son of Henri de le Pasture, a cutler in Tournai, and Agn?s de Watreloz. His birthdate is estimated from the facts that he was stated to be 35 in April 1435 and 43 in September 1441. Before or in 1427 he married Elisabeth Goffaert (c. 1405-77), whose father was a prosperous shoemaker in Brussels. Rogier may have lived for a time in Brussels: his eldest child Cornelis (b 1427) was sometimes referred to as 'de Bruxella' but was not necessarily a native of Brussels. On 5 March 1427 'Rogelet de le Pasture, natif de Tournai' was apprenticed to the Tournai painter Robert Campin. This Rogelet duly completed his apprenticeship in 1431 and on 1 August 1432 became a master of the Tournai guild. Despite much debate, it would appear that Rogelet was Rogier van der Weyden, though it has also been argued that in 1427 Rogier was a married man well past the normal age of apprenticeship and that Rogelet must have been a second Tournai painter of the same name. JACQUES DARET, however, was in his twenties when in 1428 he was apprenticed to Campin, and other instances can be cited of married apprentices. The political situation at Tournai in 1427-8 was unusual, and the guild system was not functioning normally.
