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 :. | Detail of Madonna of the Rocks | Study of a child | Studies for a Nativity | Virgin of the Rocks | Reverse side of the portrait of Ginevra de' Benci |

Michiel Jansz. van Mierevelt
(Delft, 1567 - Delft 27 June 1641) was a Dutch Golden Age painter. He was the son of a goldsmith, who apprenticed him to the copperplate engraver Hieronymus Wierix. He subsequently became a pupil of Willem Willemz and Augusteyn of Delft, until Anthonie van Montfoort (Houbraken calls him Antony Blokland), who had seen and admired two of Mierevelt's early engravings, Christ and the Samaritan and Judith and Holofernes, invited him to enter his school at Utrecht. He registered as a member of the Guild of St. Luke in The Hague in 1625.Devoting himself first to still lifes, he eventually took up portraiture, in which he achieved such success that the many commissions entrusted to him necessitated the employment of numerous assistants, by whom hundreds of portraits were turned out in factory fashion. Today over 500 paintings are or have been attributed to him.The works that can with certainty be ascribed to his own brush are remarkable for their sincerity, severe drawing and harmonious color, but comparatively few of the two thousand or more portraits that bear his name are wholly his own handiwork. So great was his reputation that he was patronized by royalty in many countries and acquired great wealth. The king of Sweden and the count palatine of Neuburg presented him with golden chains; Albert VII, Archduke of Austria, at whose court he lived in Delft, gave him a pension; and Charles I vainly endeavoured to induce him to visit the English court. Though Mierevelt is chiefly known as a portrait painter, he also executed some mythological pieces of minor importance. Many of his portraits have been reproduced in line by the leading Dutch engravers of his time. He died at Delft. The Rijksmuseum in Amsterdam has the richest collection of Mierevelt's works, chief of them being the portraits of William, Philip William, Maurice, and Frederick Henry of Orange, and of the count palatine Frederick V. At the Mauritshuis in The Hague are the portraits of four princes of the house of Orange, of Frederick V as king of Bohemia, and of Louise de Coligny as a widow. Other portraits by him are at nearly all the leading continental galleries, notably at Brunswick (3), Gotha (2), Schwerin (3), Munich (2), Paris (Louvre, 3), Dresden (4), Berlin (2), and Darmstadt (3). The town hall of Delft also has numerous examples of his work.
