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 :. | Bacchus (mk05) | Study for a kneeling Leda | Portrait of Ginevra de' Benci | Mona Lisa | The Battle of Anghiari |

Johann Peter Hasenclever
1810 Remscheid-1853 Dusseldorf, German painter. His artistic talent was recognized in 1827, while he was at school in D?sseldorf. The same year he embarked on a course in architecture at the Akademie in D?sseldorf. In 1828 he turned to the study of history painting. After a difference of opinion over the theory of art with the Director of the Akademie, Wilhelm von Schadow, Hasenclever went home to Remscheid. There he taught himself portrait painting. An example of his work from this period is the portrait of Gertraude Scharff (1832-3; Remscheid, Dt. Werkzeugmus. & Heimatmus.). From 1832 to 1838 Hasenclever again studied at the Akademie in D?sseldorf in a painting class taught by Ferdinand Theodor Hildebrandt (1804-74). In portraits and humorous genre paintings Hasenclever found a field suited to his gifts. Pithy commentaries on the everyday life of the lower middle classes are present in all of Hasenclever's work. He was best known for subjects such as wine-tastings and cellar scenes, and he also made a series of Jobs pictures, humorous, ironic interpretations of popular life based on the poem 'Jobsiade', a grotesque and comic heroic epic written by Carl Arnold Kortum in 1784.

BOL, Hans
Flemish Northern Renaissance Painter, 1534-1593 Hans Bol (1534?C1593), Flemish artist, received his early training from his two uncles who were also painters. He then was the apprentice to a Mechelen watercolorist and tempera painter at the age of fourteen. Because Bol??s watercolors became so widely reproduced, he began creating miniatures on parchment. The technique earned him many international clients and a good income. In addition, Bol also produced several oil paintings, illuminated manuscripts, drawings, and engravings. He preferred to create landscapes, mythological, allegorical and biblical scenes, and genre paintings.
