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 :. | Study fur the communion | Power and ortraits | La belle Ferronire dg | Reverse side of the portrait of Ginevra de' Benci sg | Master of the Pala Sforzesca, profile of an old man |

In Vishnudharmottara Purana, Kubera is described as the embodiment of both Artha ("wealth, prosperity, glory") and Arthashastras, treatises related to it and his iconography mirrors it. Kubera's complexion is described as that of lotus leaves. He rides a man - the state personified, adorned in golden clothes and ornaments, symbolizing his wealth. His left eye is yellow. He wears a armour and necklace upto his large belly. His face should be inclined to the left, sporting a beard and moustache and with two small tusks protruding from the ends of his mouth, representing his powers to punish and bestow favours. His wife Riddhi - representing the journey of life - is seated on his left lap, with her left hand on the back of Kubera and right holding a ratna-patra ("jewel-pot"). He should be four-armed, holding a gada (mace - symbol of dandaniti - administration of justice) and a shakti (power) in his left pair and standards bearing a lion - representing artha and a shibika (a club, the weapon of Kubera). The nidhi treasures Padma and Shankha stand besides him in human forms with their heads emerging from a lotus and a conch respectively. Agni Purana states that Kubera should be installed in temples as seated on a goat with club in his hand. Kubera's image is prescribed to be of gold with multi-coloured attributes
George P.A.Healy
American Painter, 1813-1894 American painter, active also in Europe. At the age of 17 he set up a studio in Boston after receiving encouragement from Thomas Sully, who was painting portraits there. Despite his youth and lack of training, he presented himself to the society figure Mrs Harrison Gray Otis and asked if he might paint her portrait (untraced); she agreed and later sponsored Healy's first trip abroad. In 1834 he entered the studio of Antoine-Jean Gros; the French master's suicide the following year ended Healy's only sustained period of artistic study. In Gros's studio he first encountered Thomas Couture, but they did not meet again until the next decade
Pars, William
English, 1742-82 English painter. He first established himself in London as a portrait painter, exhibiting at the Society of Artists in 1760 and at the Free Society of Artists from 1761. In 1764 he won the third premium of the Royal Society of Arts for his history painting depicting Caractacus before the Emperor Claudius (untraced). In the same year he was selected by the Dilettanti Society to accompany Richard Chandler and Nicholas Revett on an archaeological expedition to Asia Minor and Greece (1764-6). His views of Classical monuments in Asia Minor were engraved and published in Ionian Antiquities (1769), while those he made in Greece, which included pioneering drawings of the Parthenon sculptures, were used in the second volume of James Stuart's Antiquities of Athens (1777).
