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 :. | Lady with Ermine | Master of the Pala Sforzesca, profile of an old man | Profile of a man | Muscle structure of the thigh | Head and shoulders Christs |

Hans Bollongier
(1600-idem, 1645) was a Dutch Golden Age still life flower painter. Bollongier was born in Haarlem. According to the RKD little is known of his early life. He became a member of the Haarlem Guild of St. Luke in 1623, and in 1675 his younger brother Horatio was named as his beneficiary. He was a specialist in bouquets of blooms. Paintings attributed to him that are not flower- or fruit still lifes are likely the work of his brother Horatio.He was an important influence on the later flower painters known as the monogrammist JF and Anthony Claesz II. He painted during a period of great productivity for Haarlem painters, during the decades after Karel van Mander published his Schilderboeck there. In Karel van Mander's book, there were a set of rules to follow to create good paintings and good drawings. Bollongier developed his own style and still observed all of these rules. His paintings were very popular, but his work was not regarded as such by contemporary Haarlem painters. As a genre, still life painting was considered inferior to historical allegories. His work today is considered part of the proof that Tulip Mania took place, although there is reason to believe that this is also just part of early Haarlem tourist propaganda. Even as early as the 17th century, gentry from Amsterdam, Leiden, and places farther away enjoyed visiting the tulip fields of Haarlem in the Spring, and paintings of tulips were as popular as the bulbs.
Carl Wimar
1828 - 1862,American painter and photographer of German birth. He arrived in St Louis in 1843. From 1846 to 1850 he studied painting under the St Louis artist Leon de Pomarede (1807-92). In 1852 he continued his studies at the Kunstakademie in Desseldorf, where he worked with Josef Fay (1813-75) and Emanuel Gottlieb Leutze until about 1856. In 1858, having once more based himself in St Louis, he travelled up the Mississippi in order to draw and photograph Indians. Wimar joined a party of the American Fur Trading Company and made several journeys between 1858 and 1860 up the Mississippi, Missouri and Yellowstone rivers in search of Indian subjects. His painting, the Buffalo Hunt (1860; St Louis, MO, Washington U., Gal. A.), became one of the original works in the collection of the Western Academy of Art. In 1861 Wimar was commissioned to decorate the rotunda of the St Louis Court-house with scenes of the settlement of the West.
