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 communion | Profiles of a young and an old man | Small devotional picture by Verrocchio | St Jerome sgyu | Annunciation |

paulus potter
Paulus Potter (baptised on November 20, 1625 in Enkhuizen ?C buried on January 17, 1654 in Amsterdam) was a Dutch painter, specialized in animals in landscapes, usually with a low point of view. Before Potter died of tuberculosis, 28-years old, he succeeded in producing about a hundred paintings, working continuously. Few details are known of Potter's life. In 1628 his family moved to Leiden, and in 1631 to Amsterdam, where young Paulus studied painting with his father, Pieter Symonsz Potter. After his mother died, his father started an affair with the wife of Pieter Codde, also living in the fancy Sint Antoniesbreestraat. For some time his father was a manufacturer of gilded leather hangings outside the city walls. Potter became a member of the Guild of Saint Luke in Delft, but by 1649, Paulus moved to The Hague, next to Jan van Goyen. Potter married in the Hague and his father-in-law, who was the leading building contractor in the Hague, introduced him to the Dutch elite. Amalia of Solms-Braunfels, a member of the stadholder's family and an art-lover, bought a painting with a pissing cow, but some court ladies seemed to have advised against it. By May 1652, after a case about delivering a new painting, he returned to Amsterdam. Potter was invited by Nicolaes Tulp, who was impressed by his civilized behavior and politeness. Potter painted his son Dirck Tulp, but only changed the face on an earlier work he was not able to sell. Paulus painted a self portrait which was at Hackwood Park, Hampshire until 1998, it is now at Elibank House, Buckinghamshire.
