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 :. | Power and ortraits | The muscles of Thorax and shoulders in a lebnden person | Madonna with the Yarnwinder after 1510 | Annunciation (detail) dg | Reverse side of the portrait of Ginevra de' Benci |

BRAY, Jan de
Dutch Baroque Era Painter, ca.1627-1697 Painter, draughtsman and etcher, son of Salomon de Bray. He spent virtually the whole of his career in Haarlem, except for the period 1686-8, when he lived in Amsterdam. After training with his father, Jan began working as a portrait painter in Haarlem in 1650, an activity he continued for the next 40 years. Between 1667 and 1684 he served on the committee for the Haarlem Guild of St Luke, whose leading members he portrayed in a picture dated 1675 (Amsterdam, Rijksmus.) that includes a self-portrait (Jan is seen standing and drawing on the left). He married three times, in 1668, 1670 and 1672. His first two wives died a year after their marriage, his third two years afterwards, and in each case the death was followed by disputes over the inheritance. Jan's bankruptcy of 1689 may have been a result of one of the lawsuits.
Giovanni da san giovanni
1592-1636 Italian painter and draughtman. He was the most distinguished of the artists working in fresco in 17th-century Florence. An eccentric personality, he was attracted by the charm and informality of northern art and by a satirical approach to Classical themes. He went to Florence in 1608 to study in the workshop of Matteo Rosselli, where he learnt both fresco and oil painting techniques and drew extensively (Baldinucci). In 1615 he painted two ceiling canvases of Putti Supporting the Impresa of Michelangelo for a room in the Casa Buonarroti and in the same period frescoed the dome of the church of the Ognissanti, Florence (completed 1615), with a choir of musician angels. He also painted five lunettes showing scenes from the Life of St Francis in the cloister (completed 1619; in situ). In 1616 his frescoed decoration of an Allegory of Florence (destr.; preparatory drawing, Florence, Uffizi, G.D.S. U. 1122F) on the fa?ade of Cosimo II de' Medici's house in Piazza della Calza won him unexpected and lasting fame. His early works also included several tabernacles, made for patrons in the town and in the surrounding countryside. The Virgin and Child with Saints
