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 :. | Study fur the Trivulzio-monument | Study fur the adoration of the Konige | Portrat of Isabella d-Este | Mona Lisa (detail) dhu | Study of the proportion of horses |

Gregorio Lopes
Gregorio Lopes (c. 1490 - 1550) was one of the most important Renaissance painters from Portugal. Gregorio Lopes was educated in the workshop of Jorge Afonso, the court painter of King Manuel I. Later he himself became court painter for both Manuel I and for his successor, John III. In 1514 he married the daughter of Jorge Afonso, and in 1520 was knighted by Prince Jorge de Lencastre and entered the Order of Santiago. The work of Gregorio Lopes mainly consists of painted religious altarpieces for various churches and monasteries in central Portugal. Between 1520 and 1525 he worked (together with Jorge Leal) in painting altarpieces for the Saint Francis Convent of Lisbon. Also in the 1520s he painted panels for the Church of Paraeso (Paradise), also in Lisbon. In his first fase, Gregorio Lopes also worked in Sesimbra, Setebal and in the Monastery of Ferreirim, in this latter case together with Cristevao de Figueiredo and Garcia Fernandes. The painter moved in the 1530s to the city of Tomar, where he painted various panels for the Round Church of the Convent of Christ (1536 - 1539) and the main altarpiece of the Church of Saint John the Baptist (1538 - 1539). His last known works include altarpieces for the Convent of Santos-o-Novo in Lisbon (1540) and the Valverde Convent, near Évora (1545).
