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 :. | la scapigliata | Annunciation (detail) st | Study of an apostle | Unfinished painting of St. Jerome in the Wilderness | The Madonna of the Carnation g |

1822-1902 American painter of English birth. At the age of eight, she and her family emigrated to America, and after three years in New York they moved to Marietta, OH. In 1841 her father took her to Cincinnati, where she exhibited and received help from artists such as the animal painter James Henry Beard (1812-93). However, she refused the offer of the city's most important art patron, Nicholas Longworth, to assist in her art studies in Boston and Europe. Instead she stayed in Cincinnati and married an Englishman, Benjamin Spencer, by whom she had thirteen children, seven living to maturity.

Bartolome Esteban Murillo
Spanish 1618-1682 Bartolome Esteban Murillo Galleries Murillo began his art studies under Juan del Castillo in Seville. Murillo became familiar with Flemish painting; the great commercial importance of Seville at the time ensured that he was also subject to influences from other regions. His first works were influenced by Zurbaran, Jusepe de Ribera and Alonso Cano, and he shared their strongly realist approach. As his painting developed, his more important works evolved towards the polished style that suited the bourgeois and aristocratic tastes of the time, demonstrated especially in his Roman Catholic religious works. In 1642, at the age of 26 he moved to Madrid, where he most likely became familiar with the work of Velazquez, and would have seen the work of Venetian and Flemish masters in the royal collections; the rich colors and softly modeled forms of his subsequent work suggest these influences. He returned to Seville in 1645. In that year, he painted thirteen canvases for the monastery of St. Francisco el Grande in Seville which gave his reputation a well-deserved boost. Following the completion of a pair of pictures for the Seville Cathedral, he began to specialise in the themes that brought him his greatest successes, the Virgin and Child, and the Immaculate Conception. After another period in Madrid, from 1658 to 1660, he returned to Seville. Here he was one of the founders of the Academia de Bellas Artes (Academy of Art), sharing its direction, in 1660, with the architect, Francisco Herrera the Younger. This was his period of greatest activity, and he received numerous important commissions, among them the altarpieces for the Augustinian monastery, the paintings for Santa Mar??a la Blanca (completed in 1665), and others.
