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 :. | Drawing of an Infant | Saint jean-Baptiste | Waiter flat anatomy of the shoulder | Portrait of Ginevra de' Benci sg | The organs of the woman |

LE SUEUR, Eustache
French painter (b. 1616/17, Paris, d. 1655, Paris). French painter and draughtsman. He was one of the most important painters of historical, mythological and religious pictures in 17th-century France and one of the founders of French classicism. He was long considered the 'French Raphael' and the equal of Nicolas Poussin and Charles Le Brun. His reputation reached its zenith in the first half of the 19th century, but since then it has been in decline, largely as a result of the simplified and saccharine image of the man and his art created by Romantic writers and painters. Nevertheless, more recent recognition of the complexity of his art has resulted in a new interest in him and in his place in the evolution of French painting in the 17th century. Despite the almost total absence of signed and dated works, the chronology of Le Sueur's oeuvre can be established with the aid of a few surviving contracts,
Jakob Alt
1789-1872 Austrian Jakob Wassermann was born on March 10, 1873, in Furth, the son of a Jewish merchant. After a childhood with many restrictions, he began his career as an office clerk, in Munich and then in Freiburg. In 1898 he moved to Vienna and eventually established himself as a writer. Derivative and imitative, Wassermanns novels showed from the outset a strong dependence upon Fyodor Dostoevsky - particularly in his fondness for the psychological probing of criminals and social outcasts - as well as the influence of the master of the romantic horror and detective story, E. T. A. Hoffmann. Wassermanns first significant work is Die Juden von Zirndorf (1897, The Jews of Zirndorf), in which his deep knowledge of his own community in F??rth and Nuremberg stands him in good stead. As in many of his other works, Wassermanns preoccupation with innocence and redemption is here interleaved with a somewhat crass depiction of depravity and superstition. Der Moloch (1902) pays tribute to the contemporary literary cult of the great city (here Vienna), seen as an all-devouring monster of sin and perversion. Caspar Hauser (1908) is probably the authors best novel; the book, based on fact, deals with the case of the mute youth who appeared one day in 1828 on the streets of Nuremberg. Resemblances to Dostoevskys The Idiot may also be noted in this tale of the rejection and contamination of innate purity by corrupt society. After Caspar Hauser Wassermanns novels and short stories become increasingly preoccupied with bizarre and perverse anecdotes and intrigue, often initially drawn from biography or the newspapers. Das Gansemannchen (1915; The Goose Man) illuminates the problem involved in simultaneous cohabitation with two wives. Christian Wahnschaffe (1919) exploits the theme of the rich mans son who rejects the world to turn toward Buddhism. Der Fall Maurizius (1928, The Mauritius Case) is a type of detective novel made colorful by excursions into hypnosis but also weighed down by a tedious mass of psychological dissection. Like Honor?? de Balzac, whom he imitated, Wassermann introduces the same characters into different novels; thus Etzel Andergast (1931) is a sequel to The Mauritius Case, and its hero, Joseph Kerkhoven, reappears in Joseph Kerkhovens dritte Existenz (1934, Joseph Kerkhovens Third Existence). Wassermann is a somewhat uneven and labored writer, and he cannot in any sense be considered a stylist. His novels are often marred by diffuseness and miasmic obscurity. At the same time his extensive output is of considerable historical interest and illuminates rather well the consequences of marriage between the new depth psychology and the popular novel of sensation and crime. He died on Jan. 1, 1934, in Alt-Aussee.
