Leonardo Da Vinci
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.

(1787-1837) was a German painter, engraver, stage designer, and architect. He was the second son of Giuseppe Quaglio and part of the large Quaglio pedigree of Italian artists involved in architecture, indoor fresco decoration, and scenography for the court theaters. He known as a landscape and architectural painter/decorator, including quadratura. He was born in Munich. He was taught perspective and scene-painting by his father, and engraving by Mettenleiter and Karl Hess. In 1819 he resigned his post as scene-painter, and occupied himself only with architecture, for which he obtained subjects in the Netherlands, Italy, France, and England. As architect in charge, Domenico Quaglio was responsible for the neogothic style of the exterior design of Hohenschwangau Castle, summer and hunting residence of King Maximilian II of Bavaria, son of King Ludwig I of Bavaria and father of King Ludwig II. Quaglio died at Hohenschwangau in 1837. Jacometto Veneziano
Italy (Venezia 1472 -1497 ) - PainterLouis Hayet
French, 1864-1940.French painter and writer. He was largely self-taught and initially earned his living as an itinerant painter-decorator. In 1881 he met Lucien and Camille Pissarro while painting landscapes near Pontoise and through them met Paul Signac in 1885 and Seurat in 1886. After a years military service at Versailles, Hayet moved to Paris in the autumn of 1887. There he began to apply to his paintings Eug?ne Chevreuls theories of colour contrast with which he had become familiar by 1881. A gifted watercolour painter, he also experimented with the ancient technique of wax encaustic, painting on a prepared cotton that allowed light to filter through. The paint surface of works such as The Grange (Beauchamp, France, priv. col., see 1983 Pontoise exh. cat., no. 1) retains a vivid tonal freshness, while the subject of crowds of peasants gathered before the Paris agricultural market reveals a debt to Pissarro. During the second half of the 1880s he became obsessed with the notion of passage
