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 Supper (detail) sg | Profile of an old man | Anatomical study of the brain and the scalp | A full-scale composition of the Virgin and Child with St Anne and the infant St John the Baptist | The Virgin and Child with St Anne |

Floris Arntzenius
(9 June 1864 - 16 February 1925) was a Dutch painter, water-colourist, illustrator and printmaker. He is considered a representative of the younger generation of the Hague School. Arntzenius was born in Surabaya on the island of Java where his father served in the Royal Dutch East Indies Army. In 1875, at the age of 11, he was sent to the Netherlands to Amsterdam to live with his aunt and uncle in order to complete his education. In 1882 he became a student of Frederik Nachtweh, under Nachtweh's supervision he gained admission to the Rijksacademie van Beeldende Kunsten. During his time at the Rijksacademie, from 1883 to 1888, his teachers included August Allebe and Barend Wijnveld, and amongst his fellow students were Isaac Israëls, George Breitner, Willem Witsen and Jan Veth. After his studies in Amsterdam he spent another two years at the Koninklijke Academie voor Schone Kunsten in Antwerp, studying under Charles Verlat. Back in Amsterdam, Arntzenuis became a member of the artist's societies Arte et Amicitiae (1890) and St. Lucas (1891), and he had a studio at the Sarphatistraat. In 1892 his mother became widowed and moved to The Hague and Arntzenuis also moved there to keep her company. Around the same time his former fellow students Isaac Israëls and George Breitner left The Hague for Amsterdam to be a part of the capital's more vibrant artistic climate. At The Hague the established painters of the first generation of the Hague School dominated artistic life. Spuistraat, 1919, Haags Historisch MuseumArntzenius became a member of the artist's society Pulchri Studio in The Hague in 1892. From 1893 to 1895 he shared Bernard Blommers' former studio with Cornelis Antonie van Waning. He also contributed illustrations to Elsevier Geïllustreerd Maandschrift from 1892 to 1894. In 1896 he was admitted to the Hollandsche Teeken Maatschappij, a society that promoted the medium of watercolours among its members. He got married in 1900, to Lide Doorman, a talented painter of floral still lives, who lived in the house opposite of Arntzenius' mother, together they had four daughters, who he frequently painted.

Fernand Khnopff
1858-1921 Belgian Fernand Khnopff Gallery Fernand Khnopff was born to a wealthy family that was part of the high bourgeoisie for generations. Khnopff's ancestors had lived in Flanders since the early 17th-century but were of Austrian and Portuguese descent. Most male members of his family had been lawyers or judges, and young Fernand was destined for a juridical career. In his early childhood (1859-1864) he lived in Bruges where his father was appointed Substitut Du Procureur Du Roi. His childhood memories of the medieval city of Bruges would play a significant role in his later work. In 1864 the family moved to Brussels. To please his parents he went to law school at the Free University of Brussels (now divided into the Universite Libre de Bruxelles and the Vrije Universiteit Brussel) when he was 18 years old. During this period he developed a passion for literature, discovering the works of Baudelaire, Flaubert, Leconte de Lisle and other mostly French authors. With his younger brother Georges Khnopff - also a passionate amateur of contemporary music and poetry - he started to frequent Jeune Belgique ("Young Belgium"), a group of young writers including Max Waller, Georges Rodenbach, Iwan Gilkin and Emile Verhaeren. Khnopff left University due to a lack of interest in his law studies and began to frequent the studio of Xavier Mellery, who made him familiar with the art of painting. On the 25th of October 1876 he enrolled for the Cours De Dessin Apres Nature ("course of drawing after nature") at the Academie Royale des Beaux-Arts en Bruxelles. At the Academie, his most famous fellow student was James Ensor, whom he disliked from the start. Between 1877 and 1880 Khnopff made several trips to Paris where he discovered the work of Delacroix, Ingres, Moreau and Stevens. At the Paris World Fair of 1878 he became acquainted with the oeuvre of Millais and Burne-Jones. During his last year at the Acad??mie in 1878-1879 he neglected his classes in Brussels and lived for a while in Passy, were he visited the Cours Libres of Jules Joseph Lefebvre at the Acad??mie Julian.
