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 :. | Equestrian monument | Mona Lisa | Lady with Ermine | Annunciation | Madonna Litta (detail sdg |

Albert Goodwin,RWS
1845-1932 English painter. During the early 1860s Goodwin studied with Arthur Hughes and Ford Madox Brown, who predicted that his pupil would become 'one of the greatest landscape painters of the age'. Hughes and Brown impressed on Goodwin the Pre-Raphaelite principles of high finish, vivid colour and working directly from nature that inform his early landscape style
Francesco Fontebasso
(4 October 1707 - 31 May 1769) was an Italian painter painter of the late-Baroque or Rococo period of Venice. He first apprenticed with Sebastiano Ricci, but was strongly influenced by his contemporary, Giovanni Battista Tiepolo. In 1761, Fontebasso visited Saint Petersburg and produced ceiling paintings and decorations for the Winter Palace. Fontebasso returned to Venice in 1768. He helped decorate a chapel in San Francesco della Vigna. He died in Venice in 1769.
Cornelis Ketel
Flemish (Resident in UK) 1548-1616 Cornelis or Cornelius Ketel (Gouda, 18 March 1548 ?C Amsterdam, 8 August 1616) was a Dutch Mannerist painter, active in Elizabethan London from 1573 to 1581, and in Amsterdam from 1581 to the early 1600s, now known essentially as a portrait-painter, though he was also a poet and orator, and from 1595 began to sculpt as well. According to Ketel's biography, written by his contemporary Karel van Mander, he seems to have wanted to concentrate on the most prestigious of the hierarchy of genres, history painting, which included mythological subjects, but after he left France he is known almost entirely as a portrait-painter. Neither England nor Holland had much demand for large history paintings during his lifetime, and none of Ketel's histories or allegorical paintings are known to have survived intact, although drawings and prints survive. He did however significantly influence the development of the largest type of painting commonly produced in the United Provinces at this period, the civic group portrait
