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 :. | Madonna of the Yarnwinder | Study fur the Sforza-Reiterstandbild | Leda fh | Benois Madonna | Study Fur the Trivulzio-monument |

James Augustus Suydam
(1819-1865) architect, lawyer, and artist; as an artist was considered one of the premier Luminism painters. He is widely known as an American landscape painter and one of the leading members of the Hudson River School. James Augustus Suydam was descended from an old New York Dutch merchant family. He graduated from New York University (then the University of the City of New York), and began his career as a businessman but turned a significant portion of his energies to painting, studying under famed artist and portrait painter Minor C. Kellogg. At the age of thirty he was elected to the Century Association. One of the "regulars" who gathered to paint at North Conway, New Hampshire, he exhibited Conway Meadows at the New York Athenaeum and Boston Athenaeum. He opened his studio at the noted 10th Street Studio Building, New York City, in 1858. The following year he was elected an honorary professional member in the prestigious National Academy of Design, which granted him full membership in 1861. He died suddenly in North Conway at the age of 46. James Suydam was described by his friend, the accomplished artist Sanford Robinson Gifford as a "thoroughly educated and accomplished man. " In addition to his work as an artist, which he began only after working in law and architecture, he was widely read and well-versed in history, philosophy, and the sciences. His work as a landscape painter reflects this breadth of knowledge and reveals Suydam as a deeply spiritual individual. Using his familiarity with science, Suydam reduced nature to calm, clean, planar forms, and then distorted proportional relations so that God's creations loomed superior over the work of man. The National Academy has most of his works such as Paradise Rocks (1865), and the Taft family's Taft Museum also holds works. The Taft also has a podcast website for this artist. A painting of Gifford's from 1859 which Suydam, according to a report, "donated to the [National] academy in 1865," became the subject of a deaccession controversy at the Academy in late 2008.
