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 :. | Drawing of an Infant | Interior view of the Schadels | the last supper | Mona Lisa | Reverse side of the portrait of Ginevra de' Benci sg |

George Stubbs
1724-1806 George Stubbs Galleries George Stubbs (born in Liverpool on August 25, 1724 ?C died in London July 10, 1806) was a British painter, best known for his paintings of horses. Stubbs was the son of a currier. Information on his life up to age thirty-five is sparse, relying almost entirely on notes made by fellow artist Ozias Humphry towards the end of Stubbs's life. Stubbs was briefly apprenticed to a Lancashire painter and engraver named Hamlet Winstanley, but soon left as he objected to the work of copying to which he was set. Thereafter as an artist he was self-taught. In the 1740s he worked as a portrait painter in the North of England and from about 1745 to 1751 he studied human anatomy at York County Hospital. He had had a passion for anatomy from his childhood, and one of his earliest surviving works is a set of illustrations for a textbook on midwifery which was published in 1751. In 1755 Stubbs visited Italy. Forty years later he told Ozias Humphry that his motive for going to Italy was, "to convince himself that nature was and is always superior to art whether Greek or Roman, and having renewed this conviction he immediately resolved upon returning home". Later in the 1754 he rented a farmhouse in the village of Horkstow,Lincolnshire, and spent 18 months dissecting horses. He moved to London in about 1759 and in 1766 published The anatomy of the Horse. The original drawings are now in the collection of the Royal Academy. Even before his book was published, Stubbs's drawings were seen by leading aristocratic patrons, who recognised that his work was more accurate than that of earlier horse painters such as James Seymour and John Wootton. In 1759 the 3rd Duke of Richmond commissioned three large pictures from him, and his career was soon secure. By 1763 he had produced works for several more dukes and other lords and was able to buy a house in Marylebone, a fashionable part of London, where he lived for the rest of his life. Whistlejacket. National Gallery, London.His most famous work is probably Whistlejacket, a painting of a prancing horse commissioned by the 2nd Marquess of Rockingham, which is now in the National Gallery in London. This and two other paintings carried out for Rockingham break with convention in having plain backgrounds. Throughout the 1760s he produced a wide range of individual and group portraits of horses, sometimes accompanied by hounds. He often painted horses with their grooms, whom he always painted as individuals. Meanwhile he also continued to accept commissions for portraits of people, including some group portraits. From 1761 to 1776 he exhibited at the Society of Artists, but in 1775 he switched his allegiance to the recently founded but already more prestigious Royal Academy. Stubbs also painted more exotic animals including lions, tigers, giraffes, monkeys, and rhinoceroses, which he was able to observe in private menageries. He became preoccupied with the theme of a wild horse threatened by a lion and produced several variations on this theme. These and other works became well known at the time through engravings of Stubbs's work, which appeared in increasing numbers in the 1770s and 1780s. Mares and Foals in a Landscape. 1763-68.Stubbs also painted historical pictures, but these are much less well regarded. From the late 1760s he produced some work on enamel. In the 1770s Josiah Wedgwood developed a new and larger type of enamel panel at Stubbs's request. Also in the 1770s he painted single portraits of dogs for the first time, while also receiving an increasing number of commissions to paint hunts with their packs of hounds. He remained active into his old age. In the 1780s he produced a pastoral series called Haymakers and Reapers, and in the early 1790s he enjoyed the patronage of the Prince of Wales, whom he painted on horseback in 1791. His last project, begun in 1795, was A comparative anatomical exposition of the structure of the human body with that of a tiger and a common fowl, engravings from which appeared between 1804 and 1806. Stubbs's son George Townly Stubbs was an engraver and printmaker.
Henry Wyatt
(1460-1537) was an English courtier. A Lancastrian supporter against Richard III, he was imprisoned in the Tower of London. On the accession of Henry VII, he was released and assumed high places at court. He acted as Henry's agent in Scotland. He was admitted to the privy council, and remained high in the royal favour. He was one of Henry VII's executors, and one of Henry VIII's guardians. He was admitted to the privy council of the new king in April 1509, and became a knight of the Bath on 23 July of the same year. In 1511 he was made jointly with Sir Thomas Boleyn constable of Norwich Castle, and on 29 July of the same year was granted an estate, Maidencote, at Estgarstone in Berkshire. At the battle of the Spurs he served in the vanguard (16 August 1513).
