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 :. | The madonna with the Children | The annunciation | Annunciation sgt66 | Woman portrait | Funf studies of grotesque faces |

Pierre de Valenciennes
Toulouse 1750-Paris 1819 .French painter. He trained at the academy in Toulouse under the history painter Jean-Baptiste Despax (1709-73). In 1769 he went to Italy for the first time, with Mathias Du Bourg, a councillor at the Toulouse parliament. Du Bourg introduced him to Etienne-Fran?ois, Duc de Choiseul, a keen patron of the arts, who in turn recommended him to Gabriel-Fran?ois Doyen, one of the leading history painters in Paris, whose studio he entered in 1773. Doyen gave his pupil a sense of the elevated ideals of history painting but was also sympathetic to the lesser genre of landscape. Valenciennes presumably frequented Choiseul's country seat at Chanteloup, near Amboise, meeting there the landscape painters Hubert Robert and Jean Hoeel, both proteg's of Choiseul. His early interest in the native landscape can be seen in his sketchbooks (Paris, Louvre), especially one dated 1775 that contains drawings made at Amboise, Compiegne and Fontainebleau
John Robert Cozens
British 1752-1797 ). Painter, draughtsman and printmaker, son of (1) Alexander Cozens. He was taught by his father, and an album by John Robert (Aberystwyth, N. Lib. Wales) indicates that he also learnt to sketch landscape directly from nature. The album contains drawings that record sketching tours to Nacton, near Ipswich, Suffolk (Aug 1768); day trips to the outskirts of London: Greenwich and Blackheath (1768, 1771), Epsom (1768) and Hampstead (1770-71); and a trip to Matlock, Derbys (June 1772). The earliest of these sketches are careful pencil drawings, some later reworked in pen, ink and wash, and there is at least one attempt at added colour. Later drawings are freer, either noting an idea for a composition or recording light and shade with rapid washes of ink over pencil. His father worked mainly in monochrome brown or grey washes, and John Robert earliest exhibits (he exhibited at the Society of Artists every year from 1767 to 1771) were also in this medium.
Joseph Badger
(ca.1707-1765) was a portrait artist in Boston, Massachusetts in the 18th-century. He painted some 80 portraits of merchants, businessmen, clergy, and other notables, and their wives and children. Badger was born in Charlestown, Massachusetts, to tailor Stephen Badger and Mercy Kettell. In 1731 he married Katharine Felch; they moved to Boston around 1733. He was a member of the Brattle Street Church. He "began his career as a house-painter and glazier, and ... throughout his life continued this work, besides painting signs, hatchments and other heraldic devices, in order to eke out a livelihood when orders for portraits slackened."
