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 organs of the woman | Annunciation sgt66 | Madonna with the Yarnwinder (detail) dft | Profile of an old man | Profiles of a young and an old man |

GHEERAERTS, Marcus the Younger
Flemish Baroque Era Painter, ca.1561-1636 was an artist of the Tudor court, described as "the most important artist of quality to work in England in large-scale between Eworth and Van Dyck" He was brought to England as a child by his father Marcus Gheeraerts the Elder, also a painter. He became a fashionable portraitist in the last decade of the reign of Elizabeth I under the patronage of her champion and pageant-master Sir Henry Lee, introducing a new aesthetic in English court painting that captured the essence of a sitter through close observation. He became a favorite portraitist of James I's queen Anne of Denmark, but fell out of fashion in the later 1610s. Marcus Gheeraerts the Younger was the son of the artist Marcus Gheeraerts the Elder and his wife Johanna. Hardly anything is known of the paintings of the elder Gheeraerts, although his work as a printmaker reached around Europe. Like other Protestant artists, Gheeraerts the Elder fled to England with his son to escape persecution in the Netherlands under the Duke of Alva. His wife was a Catholic and remained behind; she is assumed to have died a few years later. Father and son are recorded living with a Dutch servant in the London parish of St Mary Abchurch in 1568. On 9 September 1571, the elder Gheeraerts remarried. His new wife was Susanna de Critz, a member of an exiled family from Antwerp. It is uncertain by whom young Marcus was trained, although it is likely to have been his father; he was possibly also a pupil of Lucas de Heere. Records suggest that Marcus was active as a painter by 1586 In 1590 he married Magdalena, the sister of his stepmother Susanna and of the painter John de Critz.
