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 :. | Head and shoulders Christs | Study of the proportion of the head | Study fur the communion | The Baptism of Christ | The Verkundigung |

Francis Holman
(1729-1784) was a British maritime painter, little recognised during his own lifetime, but whose paintings are now sought aftereHe is also notable as the teacher of Thomas Luny. He was born in Ramsgate and baptized on 14 November 1729 at St Laurence-in-Thanet, Ramsgate.[1] He was the eldest son and second of six children of Francis Holman (1696-1739), and his wife, Anne Long (1707-1757). His father was a master mariner, and his grandfather a Ramsgate cooper. His younger brother, Captain John Holman (1733-1816), maintained the family shipping business and remained close to Francis throughout his life. Young Francis would certainly have been immersed in the maritime world during his up-bringing; the legacy of this early knowledge is a wealth of detail and accuracy in his later work. The moonlight Battle of Cape St Vincent, 16 January 1780 by Francis Holman, painted 1780 A sixth-rate British man of war off Dover, by Francis Holman, 1777 A small shipyard on the Thames, by Francis Holman, between 1760 and 1784Francis Holman lived in at least five addresses in Wapping on the Thames in London. He married, firstly, Elizabeth, and they produced 3 sons; John (b. 1757), and two more sons, both named Francis, who died in infancy. Elizabeth's death is unrecorded, but on 7 May 1781 he married, secondly, Jane Maxted (c.1736-1790). He was apparently childless when he wrote his will in 1783.
Pieter de Ring
(1615/1620 - 22 September 1660, Leiden) was a Dutch Golden Age painter of still lifes. became famous for his opulent, flashy still lifes or banquet pieces with fruit, a lobster, a goblet, shrimps, oysters, a rug and Chinese porcelain. His signature is often a painted ring or with the Latinised form of his name, P.Ab.Annulo. De Ring was born either in Leiden, or in Ypres in Flanders, but there is no trace of his birth in the Leiden archives, and the Ypres Archives were destroyed in August 1914. Pieter de Ring started as a mason and painted still lifes in the evening. When the hall was filled with paintings he became a pupil of Jan Davidsz. de Heem, until 1635 living in Leiden. His father Daniel died in 1648; in 1657 his mother lived in Amsterdam. De Ring himself lived in a house at Hogewoerd. There are no records in the Leiden Archive on his marriage or children. He appears not to have bought a house there nor wrote a will. What is known is that he became one of the founders a member and of the Guild of St. Luke in 1648, De Ring was buried in the Pieterskerk, Leiden on 22 September 1660 and taken to church from a house in the Nonnensteeg. If he had his studio there he probably had a view on the Leiden Academy building. If he lived on the east side of the alley he had a beautiful view on the Hortus Botanicus of Leiden, the work of Clusius.
