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 :. | Annunciation | Portrat of Isabella d-Este | Madonna and Child with St Anne and the Young St John | Portrait of a Musician dey | Madonna with the Yarnwinder (detail) dft |

BONSIGNORI, Francesco
Italian painter, Veronese school (b. 1455, Verona, d. 1519, Caldiero) Italian painter. His father, Albertus Bonsignori, was reputedly an amateur painter; and besides Francesco, the oldest and most talented of his children, three other sons, including Bernardino (c. 1476-c. 1520) and Girolamo (b c. 1479), are also recorded as painters. Barely 20 paintings and fewer than a dozen drawings have been attributed to Francesco Bonsignori.
PANTOJA DE LA CRUZ, Juan
Spanish Painter, 1553-1608 Spanish painter. He must have moved to Madrid when he was very young, receiving his training in the workshop of Alonso S?nchez Coello, painter to Philip II. On numerous occasions he declared himself to be a follower of S?nchez Coello, in whose workshop he was an oficial, and he probably collaborated to a considerable degree on many of his master's mature works. There are very few signed works by Pantoja from before the death of S?nchez Coello, although some anonymous paintings from the workshop are probably by him. In Madrid in 1587 Pantoja married a woman of some means, and by the following year, when S?nchez Coello died, he was an independent painter, aspiring to his master's position. Documentation exists from 1590 concerning portraits by Pantoja of members of the royal family including one of Don Felipe, the future Philip III (1593; Vienna, Ksthist. Mus.). On Philip's accession to the throne in 1598 Pantoja painted another portrait of him (Vienna, Ksthist. Mus.) and became the official portrait painter for the court and for the nobility of Madrid; there is detailed documentation for his work from this time. He painted clothing and jewels with precision, in minute detail and with a dry objectivity in the Flemish tradition. His treatment of faces, however, clearly reveals his study of Venetian portraiture, and in particular that of Titian, as well as sharp psychological penetration. In his portraits of royal children he maintained, albeit with a certain rigidity, the charm that S?nchez Coello in his paintings had given these infant figures tightly swathed in official robes
