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 Baptism of Christ | Portrait of a Lady at the Court of Milan (san05) | The Virgin and Child with Anne (mk05) | Study of a child | The Madonna of the Carnation |

Andrea del Verrocchio
Italian Early Renaissance Sculptor, ca.1435-1488 Florentine sculptor and painter, whose real name was Andrea di Michele di Francesco di Cioni. He was a leading figure in the early Renaissance, and his workshop was a center for the training of young artists in Florence. A virtuoso metalworker, Verrocchio was primarily concerned with the spirited rendering of movement and the elaboration of detail. Many of his paintings are lost. Of the remaining panels, his hand is evident in the Baptism of Christ (Uffizi), assisted by Leonardo da Vinci. In the Pistoia altarpiece he was aided by Lorenzo di Credi. Other attributions are Tobias and the Angel (National Gall., London), two paintings of the Madonna and Child (National Gall., London; Berlin), and a Crucifixion with Saints (Argiano). Most of Verrocchio's achievements in sculpture have survived. His earlier work includes the bold group Incredulity of St. Thomas (Orsanmichele). In 1472 he designed the tombs of Piero and Giovanni de' Medici (San Lorenzo). In the same period he created the graceful Boy with a Dolphin and a lithe portrayal of David (Bargello). He went to Venice (c.1480) to work on the equestrian monument of the condottiere Bartolomeo Colleoni.

Hesselius Gustavus
American portrait painter. 1682-1755 He was trained in Sweden as a wood-engraver, gilder and painter. In 1712 he accompanied his brother, a Lutheran pastor, to America, where he settled in Philadelphia, PA. About 1720 he moved to the Annapolis, MD, area, returning before 1730 to Philadelphia, where he lived until his death. He was one of the first European-trained painters to settle permanently in America and introduced a greater technical skill and increased realism into Colonial painting. His painterly, atmospheric style, which derived from European Baroque, contrasted with the more linear technique of American-born painters. During most of his career he was the leading painter of the Middle Colonies. In addition to mythological scenes, altarpieces and portraits of prominent individuals, Hesselius undertook utilitarian work that included painting the country seat at Springettsbury of Thomas Penn (1702-75) and the interior of the Pennsylvania State House, as well as flower-boxes,
