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 :. | Madonna with the Yarnwinder (detail) dft | Madonna Litta ey | Mona Lisa | Annunciation sgt66 | Portrait of Ginevra de Benci |

During his lifetime, he was prolific and versatile, painting allegories, landscapes, and large-scale works for churches and convents. However, today he is remembered mostly for his still lifes. In the 1620s, He popularized still life painting in Madrid.Juan van der Hamen y (Gemez de) Leen was born in Madrid in 1596 but he was baptized late on April 8, 1596 in Madrid, therefore, he must had been born there just days before that date. He was the son of Jehan van der Hamen, a Flemish courtier, who had moved to Madrid from Brussels before 1586, and Dorotea Whitman Gemez de Leen, a half-Flemish mother of noble Toledan ancestry [1]. Van der Hamen and his two brothers Pedro and Lorenzo (both of whom were writers) emphasized their Spanish roots by using all or part of their maternal grandmother's family name, Gemez de Leen.. The painter's father, Jan van der Hamen, had come to Spain, as an archer, to the court of Philip II were he settled, married, and his children were born. According to 18th-century sources, the artist's father had also been a painter, but there is no evidence for this. Juan van der Hamen inherited his father's honorary positions at court and also served as unsalaried painter of the king. Van der Hamen's artistic activity in the service of the crown is first recorded on 10 September 1619, when he was paid for painting a still-life for the country palace of El Pardo, to the north of Madrid.
