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 :. | Master of the Pala Sforzesca, profile of an old man | anna sjalv tredje | Six studies fur naked or clothed men | Unfinished painting of St. Jerome in the Wilderness | The Last Supper |

Peder Als
Peder Als, a Danish historical and portrait painter, born at Copenhagen in 1725, studied for some time under C. G. Pile. After gaining the first great prize given by the academy at Copenhagen in 1755, he went to Rome and entered the school of Mengs. He occupied himself chiefly in copying the pictures of Raphael and Andrea del Sarto, which it is said that he did with great accuracy. He also copied Correggio and Titian. On his return to his own country he painted some good portraits; but his colouring was too sombre to give a pleasing effect to his pictures of females, and his work was frequently so laboured as to be deprived of all animation. Copies of the works of the old masters by Als are to be seen in Denmark. He died in 1775.
Jean-Baptiste Deshays
French Baroque Era Painter, 1729-1765 was a French painter of religious and mythological subjects.His first training was under his father, the minor Rouen painter Jean-Dominique Deshays, he then spent a little time under Jean-Baptiste Descamps at his Ecole Gratuite de Dessin. He spent time in Hyacinthe Collin de Vermont's Paris studio from around 1740 to 1749 and Jean Restout II's from late 1749 to 1751. Both these had been pupils of Jean Jouvenet, and painted in the Grand Style of French history painting, a style Deshays adopted as his own. While he was in Restout's studio, Deshays entered the Prix de Rome competition, winning second prize in 1750 with His 1750 Laban Giving his Daughter in Marriage to Jacob won the second prize in the Grand Prix de Rome, and his 1751 Job on the Dung-hill the first prize. Deshays served the compulsory three years training at the Ecole des Eleves Prot??g??s (where he learnt from Carle van Loo, its director, and attracted some religious commissions, including two vast canvases, a Visitation and an Annunciation, for the monastery of the Visitation at Rouen), before going to Rome.
