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 :. | Raffaello Sanzio named Raffael Portrat of Lorenzo de Medici | Gekrose of the intestine and its Gefabsystems | Studies of horses | Studies fur the adoration of the Konige | Leda |

Agnolo Gaddi
Italian Early Renaissance Painter, ca.1345-1396 Son of Taddeo Gaddi. Through both his brother Giovanni and his father, Agnolo was heir to the Giottesque tradition and to a successful family enterprise, which he directed with enormous success up to the turn of the 15th century. He is first mentioned as a painter in 1369, when he assisted his brother Giovanni and Giovanni da Milano in decorations for Urban V (reg 1362-70) in the Vatican. Although he probably did not assume full responsibility for the workshop until his brother Giovanni death, he must have begun accepting his own commissions as early as the 1370s. The nature of his early work and whether it included an altarpiece dated 1375 (Parma, G.N., 435), however, remains a matter of debate. Logical or likely though it may be, the notion that this early activity developed out of his brother Giovanni still little-known art is hypothetical. Whereas the works grouped around Giovanni name are all small panels, Agnolo was an artist who, like his father, excelled in wall painting. Indeed, three monumental fresco cycles (see below), in the Castellani Chapel (painted c. 1384) and the choir (painted c. 1388-93) of Santa Croce, Florence, and the chapel of the Sacra Cintola (doc. 1393-5) in Prato Cathedral, constitute the artist most notable surviving works and offer a basis for reconstructing the content and chronology of his oeuvre.
NEER, Eglon van der
Dutch Baroque Era Painter, ca.1634-1703 Son of Aert van der Neer. His birth date is based on Houbraken's statement that the artist was 70 years old when he died. He apparently studied first with his father and then with the genre and history painter Jacob van Loo. According to Houbraken, van der Neer was in France c. 1654, where he served as painter to the Counts of Dona, Dutch governors of the principality of Orange. He returned to Holland by 1659 and is recorded as a resident of Amsterdam at the time of his marriage to Maria van Wagensvelt in Rotterdam on 20 February 1659.
