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 :. | Profile of a man | Studies of children | Study fur the communion | Abendmahl | The Last Supper |

Joseph Whiting Stock
1815-1855 American painter. He was physically handicapped and confined to his house until his doctor advised a wheelchair, which, when placed on a railway carriage, allowed him to travel. He took painting lessons as therapy from Franklin White, a pupil of Chester Harding, and became proficient as an artist. This enabled him to make a living painting portraits, landscapes and miniatures throughout New England and part of New York State. He kept a journal that lists 912 examples of his work executed between 1832 and 1846, with the names of his sitters, canvas sizes, the prices charged and where the pictures were painted. No examples of his landscapes have survived and only a few of his 80 miniatures have been located. The earliest miniatures date from 1836, but most were executed in 1842 and 1845 when he lived in New Bedford, MA. Few American primitive artists of the 19th century were as productive as Stock.
Thomas Danby
(c. 1818 - 25 March 1886) was an English landscape painter. Danby was born, it is thought, in Bristol in south-west England, the younger son of Francis Danby (1793-1861). He had an elder brother, James Francis Danby (1816-75) who also became a landscape painter. Thomas went with his father to Europe in 1829, living for a time in Paris where he was able to earn a living by copying pictures at the Louvre in Paris. He thus became an earnest admireer and "student" of Claude Lorrain, whose aerial effects he sought to imitate. Returning to England about the same time as his father, he first exhibited at the British Institution in 1841, and afterwards frequently at the Royal Academy from 1843. He was a friend of Paul Falconer Poole, with whom he shared a house in Hampstead in 1843, and imbibed not a little of his romantic feeling for nature. From 1855 to his death, Danby resided in or near Hampstead in north London.. The subjects of his landscapes were usually taken from Welsh scenery, especially the old county of Merioneth; his pictures for the most part were not ideal compositions (unlike his father's work) but actual scenes pervaded with a true romantic spirit. "He was always trying" says the writer of his obituary in The Times newspaper, "to render his inner heart's feeling of a beautiful view rather than the local facts received on the retina." He came, it is said, within one vote of election as an Associate of the Royal Academy (ARA) but, failing eventually to attain Academy honours, he devoted himself in his latter years chiefly to watercolour painting. He became a member of the Royal Hibernian Academy in 1860, an associate of the Society of Painters in Watercolours in 1867, and a full member of the latter in 1870; until his death his contributions were prominent amongst the works at the society's exhibitions. Danby died of a chest complaint, terminating in dropsy on 25 March 1886. He had been twice married, and had 2 daughters and a son from the second marriage.
