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 :. | Anatomy of the Schadels | The Virgin and St Anne | The Annunciation | Annunciation sgt66 | Mona Lisa |

Rufus Hathaway
American country painter , 1770-1822 American painter and physician. He may have been apprenticed to ship-carvers and decorators, but he was not trained in fine art. His earliest known portrait, Lady with her Pets (1790; New York, Met.), demonstrates his unsophisticated, decorative style. Between 1790 and 1796 he seems to have worked as an itinerant artist; only portraits of relatives and friends survive. During his life he painted at least 25 portraits as well as miniatures, views and decorative overmantels. He also painted a genre subject, the Welch Curate, c. 1800
Johann Gottfried Schadow
1764-1850 Berlin, He was a German sculptor. He was born in Berlin, where his father was a poor tailor. Friederike von Preuben.His first teacher was an inferior sculptor, Tassaert, patronized by Frederick the Great; the master offered his daughter in marriage, but the pupil preferred to elope with a girl to Vienna, and the father-in-law not only condoned the offence but furnished money wherewith to visit Italy. Three years' study in Rome formed his style, and in 1788 he returned to Berlin to succeed Tassaert as sculptor to the court and secretary to the Academy. Over half a century he produced upwards of two hundred works, varied in style as in subjects.
ZIMMERMANN Johann Baptist
German painter, Bavarian school (b. 1680, Wessobrun, d. 1758, Menchen). Painter and stuccoist. Much of his early stuccowork and frescoes, such as that in the choir of Gosseltshausen parish church (1701) and the refectories of the abbeys at Tegernsee, Weyarn and Beyharting (before 1710), has been destroyed. His earliest surviving stuccowork (1707-9) is in the pilgrimage church of Maria Schnee, near Markt Rettenbach, and reveals the influences of Johann Schmuzer from Wessobrunn and an Italian stucco workshop that practised in Tegernsee.
