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 :. | Studies of horses | Study fur the communion | The Benois Madonna | Lady with the ermine | Madonna with the Yarnwinder |

Alfred Hirv
(born March 26, 1880 in Pechory - died May 26, 1918 in Pskov) was an Estonian painter, known especially for his still lifes. For a time he studied with Julius von Klever in Saint Petersburg; further studies took him to Rome and Munich, where he studied at the school of Anton Ažbe. His paintings are reminiscent of the style of the Dutch Golden Age. Works by Hirv can be found in the Estonian Art Museum.
Wallerant Vaillant
Wallerant Vaillant, (Lille 30 May 1623 - Amsterdam 28 August 1677), was a painter of the Dutch Golden Age and one of the first artists to use the mezzotint technique, which he probably helped to develop. Wallerant Vaillant was the oldest of five brothers, who all became successful painters. Jacques (1625 - 1691) traveled to Italy where he joined the Bentvueghels in Rome with the nickname Leeuwrik, and settled later in Berlin. Jan (1627 - 1668+) was an engraver considered to be a member of the school of Frankenthal and later became a merchant in Frankfurt. Bernard (1632 - 1698) accompanied Wallerant on all of his travels, and settled later in Rotterdam, where he became deacon of the Wallonian Church. Andreas (1655 - 1693), the youngest, became an engraver in Paris, and died in Berlin visiting his brother Jacques. It is said Wallerant was a student of Erasmus Quellinus II (1607 - 1678) in Antwerp. He moved with his parents in 1643 to Amsterdam. In 1647 he lived in Middelburg, but in 1649 he was back in Amsterdam. In 1658 he traveled with his brother to Frankfurt and Heidelberg. He helped invent the Mezzotint technique (schraapkunst, or zwartekunst) with Prince Rupert of the Rhine when he was his tutor performing experiments in etching techniques. In 1659 he went to Paris with Philibert de Gramont where he stayed five years.
