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 :. | The Madonna of the Carnation | Study for a kneeling Leda | Madonna Benois Madonna with a Flower | Study of a child | The Last Supper |

Alexander Ivanov
1806-1858 Russian Alexander Ivanov Galleries was a Russian painter who adhered to the waning tradition of Neoclassicism but found little sympathy with his contemporaries. Ivanov studied together with Karl Briullov at the Imperial Academy of Arts under his father, Andrey A. Ivanov. He spent most of his life in Rome where he befriended Gogol and succumbed to the influence of the Nazarenes. He has been called the master of one work, for it took 20 years to complete his magnum opus, The Appearance of Christ before the People (1837-57). It was for the next generation of art critics to do him justice. Some of the numerous sketches he had prepared for The Appearance have been recognized as masterpieces in their own right. Although Ivanov's major painting is a gem of the Tretyakov Gallery, the most comprehensive collection of his works can be viewed at the Russian Museum in St Petersburg.
BARTOLOMEO DI GIOVANNI
Italian Early Renaissance Painter, active 1475-1511 Bartolomeo di Giovanni, also known as Bartolommeo di Giovanni and as Alunno di Domenico, was an early renaissance Italian painter of the Florentine School who was active from about 1480 until his death in 1501. He studied with and assisted Domenico Ghirlandaio, painting the predella of Ghirlandaio's Adoration of the Magi in the Ospedale degli Innocenti (Foundling Hospital) in Florence, in 1488. Bartolomeo di Giovanni also worked under the guidance of Sandro Botticelli.
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.
