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 :. | Adoration of the Magi | Study fur the head of a Madchens | Mona Lisa | Virgin of the Rocks | The Fotus in the Uterus |

william holman hunt,o.m.,r.w.s
1827-1910 English painter. He worked as an office clerk in London from 1839 to 1843, attending drawing classes at a mechanics' institute in the evenings and taking weekly lessons from the portrait painter Henry Rogers. Holman Hunt overcame parental opposition to his choice of career in 1843, and this determined attitude and dedication to art could be seen throughout his working life. In July 1844, at the third attempt, he entered the Royal Academy Schools. His earliest exhibited works, such as Little Nell and her Grandfather (exh. British Institution, 1846; Sheffield, Graves A.G.), reveal few traces of originality, but the reading of John Ruskin's Modern Painters in 1847 was of crucial importance to Holman Hunt's artistic development. It led him to abandon the ambitious Christ and the Two Marys (Adelaide, A.G. S. Australia) in early 1848, when he realized its traditional iconography would leave his contemporaries unmoved. His next major work, the Flight of Madeline and Porphyro during the Drunkenness Attending the Revelry (1848; London, Guildhall A.G.), from John Keats's 'Eve of St Agnes', though displaced into a medieval setting, dramatized an issue dear to contemporary poets and central to Holman Hunt's art: love and youthful idealism versus loyalty to one's family. His first mature painting, it focuses on a moment of psychological crisis in a cramped and shallow picture space.
