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 :. | Aurelio Luini attributed, profile of an old man | The Annunciation | The Virgin and St Anne (mk08) | Cecila Gallerani (mk45) | Mona Lisa |

Giovanni dal ponte
Italian Painter, 1385-1437 He was reputed to have been a student of Spinello Aretino. He acquired the name dal Ponte due to the location of his studio at Santo Stefano a Ponte, Florence. He joined the Arte dei Medici e degli Speziali in 1410 and the Compagnia di S Luca in 1413. Outstanding debts brought him a prison sentence in 1424, but he still owed money to a carpenter three years later. By the late 1420s he had opened his own studio and formed a partnership with the painter Smeraldo di Giovanni (c. 1365-after 1442). Giovanni dal Ponte's varied and prolific production, which continued until his death, included fresco cycles, panels and the decoration of small objects. A number of allegorical panel paintings and cassoni are attributed to him. The animated, stylized figures in the Seven Liberal Arts (1435; Madrid, Prado) are shown in a garden dotted with naturalistic flowers and plants. His early work shows the impact of the Late Gothic style.
Herman van der Mijn
(1684, Amsterdam - 1741, London), was an 18th century painter from the Northern Netherlands. According to Houbraken he introduced Jan van Nickelen to Jan Frans van Douven. According to the RKD he learned to paint flowers from Ernst Stuven, and became a master of the Antwerp Guild of St. Luke in 1712, and the following year court painter to Johann Wilhelm, Elector Palatine. He took the family of Jan van Nickelen in tow to Dusseldorp, where they painted at court, and Van der Mijn taught Van Nickelen's daughter Jacoba Maria van Nickelen to paint flowers. She met the painters Rachel Ruysch and Willem Troost (whom Jacoba married) there. Van der Mijn returned to the Netherlands in 1717, but left on a trip via Brussels and Paris to London, where he stayed until 1737, when he took a trip to Leeuwarden
