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 Battle of Anghiari | Madonna of the Rocks | Portrait of Cecilia Gallarani | Saint John the Baptist | Study of a child |

PRETI, Mattia
Italian Baroque Era Painter, 1613-1699 Italian painter and draughtsman. Although he was trained and had his first success as a painter in Rome during the 1630s and 1640s, he is traditionally associated with the Neapolitan school. It was in Naples between 1653 and 1660 that he made his most lasting mark (see fig. 1), contributing to the evolution of the exuberant late Baroque style and providing an important source of inspiration to later generations of painters, notably to Francesco Solimena. From 1661 he was based in Malta, where his most substantial undertaking was the decoration of St John's, Valletta. Preti's mature style is intensely dramatic and unites a Caravaggesque realism and expressive chiaroscuro with the grandeur and theatricality of Venetian High Renaissance painting.
Loo, Louis-Michel van
Flemish active in France, 1707-1771 Painter, son of Jean-Baptiste van Loo. He trained with his father in Turin and Rome, later attending the courses of the Acad?mie Royale in Paris. He received the institution's first prize for painting in 1726, and in 1728, accompanied by his brother, Fran?ois, and his uncle, Carle, returned to Rome where he was associated with Francois Boucher. On his way back to France, he stayed for a time in Turin, painting portraits of the royal family of Sardinia, the Duke and Duchess of Savoy. In Paris he was admitted to membership of the Acad?mie Royale and in 1735 was appointed assistant teacher at the Academie, becoming renowned as a specialist in portrait painting. Most of his portraits from this period are half-length, combining ideas from Hyacinthe Rigaud's later work with other more natural and innovative ones. On the death of Jean Ranc, Philip V of Spain asked Rigaud to suggest a substitute, and van Loo was proposed. He arrived in Madrid in 1737 and remained there as Pintor de la Corte until 1752, responding with modern aesthetic ideas to the demands of the Spanish monarchs for pomp and splendour. He carried out court commissions but devoted part of his time to teaching, his pupils often becoming studio assistants. He also took an active part in meetings held over a number of years to establish the Real Academia de Bellas Artes de S Fernando, for which he produced the canvas, the Education of Cupid by Venus and Mercury
