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 :. | Annunciation (detail) sg77 | St Jerome sgyu | Studies fur the adoration of the Konige | The Refectory with the Last Supper after restoration g | Lady with the ermine |

Pater, Jean-Baptiste
French Rococo Era Painter, 1695-1736 French painter and draughtsman. He was taught in Valenciennes by Jean-Baptiste Guid? (master 1697; d 1711) and also by his father, Antoine Pater (1670-1747), a sculptor whose portrait was painted by Antoine Watteau (Valenciennes, Mus. B.-A.), who was also a native of Valenciennes. He probably followed Watteau to Paris after the short stay that the latter made in Valenciennes around 1710. Pater thus became a pupil of Watteau. Watteau's difficult character led to Pater's dismissal. He then spent a few hard years on his own in Paris, before returning to Valenciennes around 1715 or 1716. He tried to work independently of the local corporation of St Luc, of which he was not a member; a number of comical legal difficulties ensued, and Pater returned to Paris in 1718. There he must have been in contact with Watteau, since he worked for some of the latter's clients, such as the dealers Pierre Sirois and Edm?-Fran?ois Gersaint, and the collector Jean de Jullienne. In the spring of 1721 the dying Watteau called Pater to him at Nogent, near Paris, apparently full of remorse for his previous attitude and wishing to instruct him in the basic tenets of his painting,
Francis Hayman
English Painter, 1708-1776,English painter and illustrator. He was in London at the age of 10, and from 1718 until c. 1725 he was apprenticed to Robert Brown (d 1753), a decorative painter. From 1732 Hayman was employed as a scene painter at Goodman's Fields Theatre, where he painted allegorical works such as The King Attended by Peace, with Liberty and Justice Trampling on Tyranny and Oppression on the pit ceiling (destr.). He moved to Drury Lane Theatre in 1736, shortly before the Licensing Act closed Goodman's Fields. At Drury Lane he painted scenery for Thomas Arne's masque The Fall of Phaeton (1736) and was praised for his naturalistic landscapes. From the late 1730s he began accepting commissions for portraits and conversation pieces. His success in the field of portraiture rested on the dearth of good portrait painters in England at the time and his exploitation of a growing middle-class clientele. Hayman painted portraits of doctors, literary men and actors.
Henry Dawson
a landscape painter, was born in Hull in 1811, but came with his parents to Nottingham when an infant, so that he always regarded the latter as his native town. His parents were poor, and he began life in a Nottingham lace factory. But even while engaged in lace-making he continued to find time for art, and used to paint small pictures, which he sold at first for about half-a-crown each. In 1835 he gave up the lace trade and set up as an artist, his earliest patron being a hairdresser in Nottingham, who possessed a taste for art. In 1844 he removed to Liverpool, where after a time he got into greater repute, and received higher prices for his works. In 1849 he came with his family to London, and settled at Croydon, where some of his best pictures were painted. Among these may be reckoned 'The Wooden Walls of Old England,' exhibited at the British Institution in 1853, 'The Rainbow,' 'The Rainbow at Sea,' 'London Bridge,' and ' London at Sunrise.' With the exception of six lessons from Pyne received in 1838, Henry Dawson was entirely a self-taught artist, and his art shows much originality and careful realism. He studied nature for himself, but he seems in later life to have been moved by Turner's influence to try more brilliant effects than he had before dared. Many of his works indeed are very Turneresque in treatment, though he can scarcely be called an imitator of Turner, for he had a distinct style of his own. Henry Dawson, though painting much, and selling his pictures for high prices in his later life, remained, strange to say, very little known except to artists and connoisseurs until the large and very interesting collection of his works that was made for the Nottingham Exhibition in 1878 brought him wider fame. This exhibition showed him to be a genuine English landscape painter, of no great imaginative or intellectual power, but who delighted in nature, and represented her faithfully to the best of his ability. He died in December 1878, at Chiswick, where he had for some time resided.
