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 :. | Virgin of th Rock (mk08) | The Virgin and St Anne | Virgin of the Rocks,completed (mk08) | Adoration of the Magi (mk08) | Annunciation (detail) sg77 |

Basilius Besler
1561-1629,was a respected Nuremberg apothecary and botanist, best known for his monumental Hortus Eystettensis. He was curator of the garden of Johann Konrad von Gemmingen, prince bishop of Eichstätt in Bavaria. The bishop was an enthusiastic botanist who derived great pleasure from his garden, which was the only important European botanical garden outside Italy. The gardens surrounded the bishop's palace, Willibaldsburg, which was built on a hill overlooking the town. These gardens had been started in 1596 and designed by Besler's colleague, Joachim Camerarius, the Younger (1534-1598), a physician and botanist. Upon Camerarius' death in 1598, Besler had the remainder of Camerarius' plants moved to Eichstätt and carried on the work of planting and supervision. The bishop commissioned Besler to compile a codex of the plants growing in his garden, a task which Besler took sixteen years to complete, the bishop dying shortly before the work was published. Besler had the assistance of his brother and a group of skilled German draughtsmen and engravers, including Sebastian Schedel, an accomplished painter, and Wolfgang Kilian, a skilled engraver from Augsburg. Kilian and his team engraved the initial copper plates, but after the bishop??s death, the operations moved to N??rnberg and a new team of engravers, among whom were Johannes Leypold, Georg Gärtner, Levin and Friedrich van Hulsen, Peter Isselburg, Heinrich Ulrich, Dominicus Custos and Servatius Raeven. Camerarius' nephew, Ludwig Jungermann (1572-1653), was a botanist and wrote the lion's share of the descriptive text. The work was named Hortus Eystettensis (Garden at Eichstätt). The emphasis in botanicals of previous centuries had been on medicinal and culinary herbs, and these had usually been depicted in a crude manner. The images were often inadequate for identification, and had little claim to being aesthetic. The Hortus Eystettensis changed botanical art overnight. The plates were of garden flowers, herbs and vegetables, exotic plants such as castor-oil and arum lilies.
