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 Refectory with the Last Supper after restoration g | The Portinari Altarpiece | Virgin of the Rocks | Annunciation (detail) dg | The Fotus in the Uterus |

SWANEVELT, Herman van
Dutch Baroque Era Painter, ca.1600-1655 Dutch painter, draughtsman and etcher, active in France and Italy. His first signed and dated works are two views of Paris dated 1623 (Brunswick, Herzog Anton Ulrich-Mus.). He was in Rome from 1629 to 1641. His earliest dated painting there is an Old Testament Scene (1630; The Hague, Mus. Bredius; see fig.), a compositional formula that he often used, with some variations, in Rome. A flat, low foreground is closed on the left by a house and a tree; on the right is a distant hilly scene; and groups of figures are disposed horizontally. This design, derived from Cornelis van Poelenburch, is well suited to van Swanevelt's many landscapes with biblical and mythological subjects. The large tree extending beyond the frame gives a monumental touch to the composition.
Antoine Rivalz
(1667, Toulouse - 1735) was a French painter. The son of Jean-Pierre Rivalz (who painted and designed the city's hôtel de ville), Antoine was the official painter to the town of Toulouse, a talented portraitist of the society of the city in the 18th century. He also produced a large number of drawings. Antoine Rivalz began his training in the studios of his father Jean-Pierre, the sculptor Marc Arcis and the artist Raymond Lafage. In his training, he was particularly interested in studying classical works and the Baroque Italian masters. From 1685 to 1687 he trained at the Academie royale de peinture et de sculpture in Paris. On his return to Toulouse he received his first two commissions. In 1687 he set out for Rome, where he stayed for more than ten years. In 1694 he won second prize at the Accademia di San Luca with a drawing of The fall of the giants, with first prize going to Antonio Balestra and Felice Nardi. In Rome he became friends with other artists such as Carlo Maratta, Luigi Garzi and Benedetto Luti, and was more and more in demand for commissions from families in both Rome and Toulouse. In 1703, he returned to Toulouse and was made painter of the city's hôtel de ville, a post he held until his death. Supported by an important studio, he received a large number of commissions - commemorative paintings, paintings of ordinance and armour, architectural projects, restorations. This post, however, allowed him above all to forge productive relations with the city's upper classes and benefit from a near-monopoly on public, religious and private commissions in the city. He married his first cousin Louise Rivalz, with whom he had six children, including the future artist Pierre Rivalz, known as the "chevalier Rivalz". In 1726 he set up Toulouse's first art school and in 1750 letters patent from Louis XV turned it into the Academie royale de peinture et de sculpture de Toulouse, the only one in France (after that in Paris) to be allowed to bear that title.
