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 :. | Cecila Gallerani (mk45) | Anatomical studies of the basin of the Steibeins and the lower Gliedmaben of a woman and study of the rotation of the arms | Madonna with a Flower | Holy Hieronymus | Madonna and Child |

George Gower
1540-1596 English George Gower Gallery Little is known about his early life except that he was a grandson of Sir John Gower of Stettenham, Yorkshire. His earliest documented works are the two 1573 companion portraits of Sir Thomas Kytson and his wife Lady Kytson, now in the Tate Gallery in London. Gower painted a self-portrait in 1579 (right) that shows his coat of arms and his artist's tools of his trade. An allegorical device shows a balance with an artist's dividers outweighing the family coat of arms, "a startling claim in England where a painter was still viewed as little more than an artisan." The Armada portrait of Elizabeth I by George Gower c. 1588Gower was appointed to the position of Serjeant Painter to Queen Elizabeth in 1581. This allowed him to paint most of England??s aristocracy. The post also made him responsible for painted decoration at the royal residences, and on coaches and furniture. Among his works were a fountain (now destroyed) and the astronomical clock, both at Hampton Court Palace. He also inspected portraits of the Queen by other artists prior to their official release. Gower's best-known work is the version of the Armada Portrait of Elizabeth now at Woburn Abbey, painted to commemorate the 1588 defeat of the Spanish Armada. (A cut down version of this painting in the National Portrait Gallery (United Kingdom) is attributed to Gower; the "Drake" version is by a different hand.)
JANSSENS, Abraham
Flemish painter (b. 1575, Antwerpen, d. 1632, Antwerpen). Flemish painter. He painted historical, religious and mythological subjects, often on a large scale, derived principally from antique sculpture and the art of Michelangelo and Raphael and, to a lesser degree, from certain contemporaries, including the Dutch late Mannerists and the Bolognese school. He was highly esteemed in Antwerp but suffered, then and subsequently, from the inevitable comparison with his contemporary and formidable rival Rubens
Esaias Boursse
1631-1672 Dutch Dutch painter and draughtsman. Boursse was the son of Walloon parents, Jacques Boursse and Anne de Forest. A testimony of 23 July 1658 states that Esaias brother Jan provided for his artistic training. There is nothing to confirm a view of the early 20th-century scholars Bode, Bredius and Valentiner that Boursse was a pupil of Rembrandt, although the two artists may have had some contact, since Rembrandt lived near Jan in Amsterdam. According to an inventory of 24 November 1671, Jan collected a number of paintings, drawings and etchings by Rembrandt.
