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 :. | Portrait of a Musician dey | Mona Lisa | Six studies fur naked or clothed men | Raffaello Sanzio named Raffael Portrat of Lorenzo de Medici | Anatomical study of the brain and the scalp |

Maurice Utrillo
French Painter, 1883-1955,French painter, son of SUZANNE VALADON. He was entrusted to his grandmother while his mother posed as a model for such painters as Renoir and Puvis de Chavannes before discovering her own talent for drawing and painting. His father, the Spanish painter Miguel Utrillo (1862-1934), only admitted paternity eight years after Maurice's birth. Maurice Utrillo had no predisposition for art, but when he was 19 his mother took medical advice and urged him to adopt drawing and painting as a distraction from his need for alcohol. In search of a suitable subject, he went to the countryside around Montmagny, a village to the north of Paris, where, between the autumn of 1903 and the winter of 1904, he completed almost 150 paintings, sombre, heavily impasted landscapes, such as the Roofs of Montmagny (Paris, Pompidou). By 1906 the doctor felt that Utrillo could return to Montmartre. His pictures of the streets and suburbs were painted with a less heavy impasto and with lighter tones.
Joseph Severn
(7 December 1793 - 3 August 1879) was an English portrait and subject painter and a personal friend of the famous English poet John Keats. He exhibited portraits, Italian genre, literary and biblical subjects, and a selection of his paintings can today be found in some of the most important museums in London, including the National Portrait Gallery, the Victoria and Albert Museum and the Tate Britain. The eldest son of a music teacher, Severn was born at Hoxton, near London, and apprenticed at the age of 14 to William Bond, an engraver. Severn was one of seven children; two of his brothers, Thomas (1801-1881) and Charles (1806-1894), became professional musicians, and Severn himself was an adroit pianist. During his early years he practised portraiture as a miniaturist.
Robert Havell Jr Prints
1793-1878 Engraver and painter, cousin of William Havell. He learnt the art of aquatint engraving from his father, Robert Havell I. He worked first in the family engraving business and then c. 1825-7 with Colnaghi in London. In 1827 he undertook the execution in aquatint of the plates for John James Audubon Birds of America, published in parts in London between 1827 and 1838. Havell engraved 425 of the plates and reworked the ten that had been engraved by William Home Lizars in Edinburgh. Havell father printed and coloured some of the double elephant folio sheets in 1827-8 after which Havell took on those tasks himself, establishing himself as a master of aquatint. Among his other important works in the medium are the plates for Mrs E. Bury Selection of Hexandrian Plants (London, 1831-4). In 1839, at Audubon invitation, Havell moved with his family to New York and embarked on a new career as a landscape painter in the style of the Hudson River school, while also working as an engraver. He settled in the Hudson River villages of Ossining (1841) and Tarrytown (1857) but painted throughout north-eastern America. View of Deerfield, Massachusetts (1847; Hist. Deerfield, MA) is characteristic of his quietly romantic idealization of his subjects. Niagara Falls from the Chinese Pagoda (1845; New York, Pub. Lib.), engraved by Havell after one of his paintings, is among the best known of his American aquatints. Though his reputation rests largely on his work for Audubon, his original subjects gave him greater opportunities to display the full range of his aquatint technique. Part of the Havell family
