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 :. | Studies for a Nativity | Adoration of the Magi | Study of a child | Detail of Madonna of the Rocks | Portrait of Ginerva de'Benci |

HALL, Peter Adolf
1739-1793 Swedish painter and collector. In 1753 he attended Uppsala Universitet to study medicine and natural history. In 1755 he went on a study trip abroad, led by his drawing-master Lars Brisman. While in Germany (1756-9) he studied miniature painting with Eichhardt in Berlin and with Karl Friedrich Wilhelm Richard (1725-70) in Hamburg. After this trip, he decided to become a professional portrait painter, and in 1759 he enrolled at the Kungliga Akademi for de Fria Konsterna in Stockholm, studying drawing with the French sculptor Pierre-Hubert Larchaveque (1721-78) and painting with Gustaf Lundberg. He attracted the attention of C. F. Adelcrantz, who in 1766 gained for him a commission for the pastel portrait of Princes Karl and Fredrik Adolf. In that year he also executed a miniature portrait of Crown Prince Gustav on the occasion of his engagement to Princess Sophia Magdalena of Denmark. Also in 1766 he received a royal travel grant to study in Paris, where he developed a completely new technique of miniature painting using sweeping brushwork and a clear and fresh range of colour that allowed for lively characterization. He made exquisite detailed studies of the backgrounds of his paintings, as well as his sitters costumes and their attributes and accessories. His new technique involved applying gouache to the ivory in a manner that allowed the ivory to show through, a method that was particularly successful in depicting drapery. The smooth surface of the ivory also allowed freer brushwork associated with full-scale portraits.

Herman Saftleven
(1609 - January 5, 1685 (buried)), was a Dutch painter of the Baroque period. Born in Rotterdam, Saftleven lived most of his life (1632-1685) in Utrecht. His brothers, Cornelis Saftleven (1607-1681) and Abraham Saftleven were both painters. The former was even better known as a painter, specializing in genre scenes, while Herman was known for his landscapes of river scenes as well as of persons traveling through woods. His father, Herman Saftleven I was a painter in Rotterdam, who died by 1627. One of Herman IIes daughters, Sara Saftleven, born in Utrecht after 1633, also became a painter of flowers in watercolors. She married Jacob Adriaensz Broers in 1671. Herman became the dean of the Guild of St Luke in Utrecht. After a storm had destroyed most of the town in the 1670s, he sold the city a series drawings he had made of Utrecht churches before they were destroyed. In the 1680s, he was commissioned by the amateur botanist and horticulturalist Agnes Block, to draw flowers and plants at her country estate near Utrecht. He died in Utrecht.
