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 :. | Last Supper | Reverse side of the portrait of Ginevra de' Benci | Annunciation (detail) dfe | La Vierge,l'Enfant Jesus et sainte Anne | Mona Lisa |

Theodule Ribot
Saint-Nicolas-d'Attez, 1823-Colombes 1891. was a French realist painter. He was born in Saint-Nicolas-d'Attez, and studied at the École des Arts et Metiers de Chalons before moving to Paris in 1845. There he found work decorating gilded frames for a mirror manufacturer; he also studied in the studio of Auguste-Barth??l??my Glaize. After a trip to Algeria around 1848, he returned in 1851 to Paris, where he continued to make his living as an artisan. In the late 1850s, working at night by lamplight, he began to paint seriously, depicting everyday subjects in a realistic style. He made his Salon debut in 1861 with several paintings of kitchen subjects. Collectors purchased the works, and his paintings in the Salons of 1864 and 1865 were awarded medals. Ribot painted domestic genre works, still-lifes, portraits, and religious scenes. His preference was for painting directly from nature, emphasizing the contrasts of light and dark. His use of chiaroscuro to suggest psychological states grew from his admiration for Spanish and Dutch baroque masters such as Ribera and Rembrandt, an enthusiasm shared by his contemporaries Courbet and Bonvin. Members of Ribot's family are the likely models for many of his figure compositions, in which the subjects engage in humble activities, such as preparing meals or gathering in groups to read to each other. The light draws attention to faces and hands, which emerge sharply from dimly lit surroundings. Although the realism of Ribot's work aligns him with the most progressive artists of the generation preceding the Impressionists, he was no revolutionary,
Jacob Grimmer
(ca. 1526-1590) was a Flemish Renaissance landscape painter. Grimmer was born and died in Antwerp. According to Karel van Mander he first learned to paint landscapes from Matthys Cock and later from Christiaen Queburgh, both of Antwerp. He was a very skilled painter of houses, sky, and foreground views. He was a member of the Guild of St. Luke who was active as a rederijker and acted in many plays. According to the RKD his earliest dated work is from 1546 and his latest dated work was 1589. Most of his works are landscapes and he worked together with Gillis Mostaert. Abel Grimmer was his son and pupil.
