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 for a Nativity | The Last Supper | Madonna of the Rocks | Detail of Madonna of the Rocks | The Annunciation |

VROOM, Hendrick Cornelisz.
Dutch Baroque Era Painter, ca.1563-1640. He was one of the founders of Dutch marine painting. Painter and draughtsman. By his own account, he received his early training in Delft, home of his mother's family. Van Mander reports that Hendrick's stepfather, like his father a ceramic artist, forced him to work as a decorator of ceramic vessels, which caused the young artist to leave home and embark on extensive travels in Spain and Italy. After working for ecclesiastical patrons in Florence and Rome, he was employed for at least two years (c. 1585-7) by Cardinal Ferdinando de' Medici, who in October 1587 succeeded Francesco I as Grand Duke of Tuscany. Ferdinando's keen interest in ships and the navy seems to have been a determining factor in Vroom's choice of subject-matter. According to Lanzi, he was known in Rome as 'Lo Spagnolo' (since he had arrived there from Spain). Among his earliest works may be a group of marine paintings attributed to him (Rome, Villa Colonna). His friendship in Rome with Paul Bril, mentioned by van Mander, had no effect on Hendrick's painting style, but Bril's influence is discernible in a group of landscape drawings
Adrian Vanson
Adrian Vanson (died c. 1602) was court portrait painter to James VI of Scotland. Adrian succeeded Arnold Bronckorst as court painter in Scotland in May 1584, and his appointment was subsequently confirmed by royal letter on 20 August 1584. Adrian Vanson was paid £8-10s in June 1581 for two pictures sent to Theodore Beza. A letter by James VI's former tutor Peter Young accompanied pictures of John Knox and George Buchanan sent to Geneva in November 1579 for the woodcuts in Beza's Icones (1580). The Scottish portraits arrived too late for the book, and the woodcuts of Knox and a James VI, thought to be by Vanson, were first published in Simon Goulart's edition of the Icones in 1581. The picture of George Buchanan, which was never published in Beza's Icones, but may have appeared in other later works, is attributed to Bronckorst. Knox from Beza's Icones, after Adrian VansonVanson also painted ceremonial spears and banners for the coronation of Anne of Denmark. When he was made a burgess of Edinburgh, it was hoped he would teach his craft to apprentices. He may have been 'Lord Seton's painter', who was recorded drawing portraits for coins at the mint in Edinburgh. There was a un-named Flemish painter working on the king's portrait at Stirling Castle in May 1579. This may have been Vanson or Bronckorst. According to the inventories of the Earl of Leicester, he had a portrait of the 'young king of Scots' in 1580, which may have been another copy of this picture. Leicester sent his own portrait to James VI, painted on canvas by Hubbard in 1583. Attributed portraits include James VI; Anne of Denmark; Patrick Lyon, Lord Glamis; Sir Thomas Kennedy of Culzean; Agnes Douglas, Countess of Argyll. Vanson's James VI of circa 1585 survives at Edinburgh castle. In May 1586 a French ambassador in Scotland, the Baron d'Esneval, promised to get Mary, Queen of Scots a copy of a recent portrait of James VI from the only painter in Edinburgh. There had been rumours of an embassy to Denmark to discuss the king's marriage in April 1586. It is thought the picture at Edinburgh Castle was made by Vanson for this embassy or a similar purpose.
