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 :. | The Annunciation | Last Supper (mk08) | The Last Supper | Mona Lisa (detail) dhu | Study of an old man |

Giovanni Santi
(c. 1435 - 1 August 1494) was an Italian painter and decorator, father of Raphael. He was born at Colbordolo in the Duchy of Urbino. He was a petty merchant for a time; he then studied under Piero della Francesca. He was influenced by Fiorenzo di Lorenzo, and seems to have been an assistant and friend of Melozzo da Forle. He was court painter to the Duke of Urbino and painted several altarpieces, two now in the Berlin Museum, a Madonna in the church of San Francesco in Urbino, one at Santa Croce on Fano, one in the National Gallery at London, and another in the gallery at Urbino; an Annunciation at the Brera in Milan; a resurrected Christ in the Museum of Fine Arts, Budapest; and a Jerome in the Lateran. He died in Urbino.

Koller, Rudolf
Swiss Painter, 1828-1905 Swiss painter. He studied in Zurich under such artists as Johann Jakob Ulrich before going to D?sseldorf in 1846 to work with Carl Ferdinand Sohn. In 1847 he was in Paris where he shared a studio with Arnold B?cklin. Two years later he went to Munich where he worked with a group of artists called the 'Schweizer', whose leader was Johann Gottfried Steffan. He returned to Zurich in 1851 and painted mainly pastoral landscapes (e.g. Waterfall near Zurich, c. 1851; Zurich, Graph. Samml. Eidgen?ss. Tech. Hochsch.) evoking prevailing romantic sensibilities. His later paintings combine realist subject-matter with a carefully arranged and executed classical composition. He frequently chose rustic farm scenes containing animals, whom he believed represented a dignified and pure image of nature that was to be treated with respect. He was often considered to be the 19th-century counterpart to Paulus Potter whose paintings of animals were emulated at the time. His works are similar to those of Rosa Bonheur, as seen in Cows in the Roman Countryside (1869; Berne, Kstmus.). His most celebrated painting is the St Gotthard Mailcoach (1873; Zurich, Ksthaus), which depicts a coach at full speed attempting to stop suddenly for a herd of cattle obstructing the narrow road. After 1870, problems with his eyesight forced him to paint less, yet even late in life he was still capable of producing such lyrical paintings as Horses at the Drinking Fountain (1890; Le Locle, Mus. B.-A.).
