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 dinner | Madonna and Child with St Anne and the Young St John | La Vierge,l'Enfant Jesus et sainte Anne | Lady with Ermine | Mona Lisa (La Gioconda) sdg |

Francis Danby
Irish Painter, 1793-1861 was a British painter of the Romantic eraBorn in the south of Ireland, he was one of a set of twins; his father, James Danby, farmed a small property he owned near Wexford, but his death, in 1807, caused the family to move to Dublin, while Francis was still a schoolboy. He began to practice drawing at the Royal Dublin Society's schools; and under an erratic young artist named James Arthur O'Connor he began painting landscapes. Danby also made acquaintance with George Petrie, and all three left for London together in 1824. This expedition, undertaken with very inadequate funds, quickly came to an end, and they had to get home again by walking. At Bristol they made a pause, and Danby, finding he could get trifling sums for water-color drawings, remained there working diligently and sending to the London exhibitions pictures of importance. There his large oil paintings quickly attracted attention. Danby painted "vast illusionist canvases" comparable to those of John Martin of "grand, gloomy and fantastic subjects which chimed exactly with the Byronic taste of the 1820s."The Upas Tree (1820) and The Delivery of the Israelites (1825) brought him his election as an Associate Member of the Royal Academy. He left Bristol for London, and in 1828 exhibited his Opening of the Sixth Seal at the British Institution, receiving from that body a prize of 200 guineas; and this picture was followed by two others on the theme of the Apocalypse. In 1829 Danby's wife deserted him, running off with the painter Paul Falconer Poole Danby left London, declaring that he would never live there again, and that the Academy, instead of aiding him, had, somehow or other, used him badly. For a decade he lived on the Lake of Geneva in Switzerland, becoming a Bohemian with boat-building fancies, painting only now and then. He later moved to Paris for a short period of time. He returned to England in 1840, when his sons, James and Thomas, both artists, were growing up. Danby exhibited his large (15 feet wide) and powerful The Deluge that year; the success of that painting, "the largest and most dramatic of all his Martinesque visions, revitalized his reputation and career. Other pictures by him were The Golden Age (c. 1827, exhibited 1831), Rich and Rare Were the Gems She Wore (1837), and The Evening Gun (1848). Some of Danby's later paintings, like The Woodnymph's Hymn to the Rising Sun (1845), tended toward a calmer, more restrained, more cheerful manner than those in his earlier style; but he returned to his early mode for The Shipwreck (1859).

Harriet Backer
Norwegian Painter, 1845-1932 Norwegian painter. In the 1860s and early 1870s she took lessons in drawing and painting in Christiania (now Oslo) and also travelled extensively in Europe with her sister Agathe, a composer and pianist. She copied works in major museums and took occasional art lessons; she later considered this experience to have been of fundamental importance to her artistic development. Little Red Riding Hood (1872; Oslo, N.G.) is impressive in technique, and the early portrait of her sister, Agathe Backer-Grendahl (1874; Holmestrand, Komm.), shows a refined colour scheme. At the age of nearly 30 Backer decided to train professionally as a painter and in 1874 went to Munich. She was never attached to a particular institution, but the influence of her friend the artist Eilif Peterssen was crucial to her development. In Munich she made a thorough study of perspective, which formed a secure basis for her later work.
