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 :. | The last dinner | Self Portrait | Landscape in the Arnotal | Madonna Litta (detail sdg | The Baptism of Christ (detail) sg |

Thomas Uwins
English Painter, 1782-1857 English painter and illustrator. He was apprenticed to the line-engraver Benjamin Smith (d 1833) in 1797, but his greater interest in portrait painting led him to take life classes at the Royal Academy, London; he exhibited portraits there from 1799. Versatile and industrious, he painted miniature likenesses, taught drawing, designed and engraved illustrations for books in French, Portuguese and English, and wrote for and illustrated Rudolph Ackermann's Repository. His half-a-crown watercolours, known as 'pretty faces', were particularly popular, and he found employment as an assiduous copyist. In 1809 he was elected to the Society of Painters in Water-Colours and for the next nine years exhibited careful and colourful images of the countryside that provided views of the year's harvest. In 1817 Uwins travelled to France to record the Burgundian grape harvest, identifying the labour force more obviously as peasants than their English counterparts. In debt, he moved in 1820 to Edinburgh, where he illustrated books by Walter Scott and painted portraits. In 1824, his debt paid, he left for Italy, where he spent seven years; he sent highly valued copies of Italian works back to England (to Thomas Lawrence among others) and made studies of life in and around Rome and Naples, from which his later successes at the Royal Academy derived. An immodest Protestant, Uwins deplored but revelled in the 'polluted streams' of Catholic Italy, and provided London with oils renowned for their clarity and colour.

At 19, with the help of a generous neighbor, Julian left Texas in order to study with the renowned American Impressionist William Merritt Chase. Julian's father, Robert, has also once studied with Chase. Julian spent the summer of 1901 on Long Island at Chase's Shinnecock School of Art. He studied with Chases for a couple of years and then moved to New York to attempt to make a living as an eu plain aire artist.
