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 Virgin and Child with Anne (mk05) | La Gioconda (The Mona Lisa) | Horses with horsemen | Study for a kneeling Leda | Leda |

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
Sebastian Stoskopff
Strasbourg 1597-Idstein 1657 was an Alsatian painter. He is considered one of the most important German still life painters of his time. His works, which were rediscovered after 1930, portray goblets, cups and especially glasses. The reduction to a few objects, which is characteristic of early still life painting, can again be recognized in Stoskopff's painting. His chief works hang in Strasbourg and in Saarbr??cken. Sebastian Stoskopff was born in 1597 in Strasbourg. His father was employed by the city since 1590 and acted as a mounted courier or royal escort, driving a one-horse-carriage. In 1614, Stoskopff's father asked the Strasbourg council for help for his 17-year-old son. He wanted him to be able to learn the craft of painting, since Sebastian had already been extremely talented in drawing and painting since he was 15. The council agreed to provide their support and probably sent the young artist at first to the Strasbourg painter and copper engraver, Friedrich Brentel. However, he only learned how to further refine his drawing and was not, as hoped, introduced to the art of painting. In 1615, Stoskopff's father died and his widowed mother went to the Strasbourg council once again to ask for support for training from a recognized painter. Stoskopff was then sent to Daniel Soreau, a painter who was active in Hanau. In the beginning, Soreau was not very enthusiastic, since he usually chose his apprentices from among his relatives and close friends. However, he finally complied with the request of the council and assured them that would "make an Albrecht Derer of this apprentice". There is not a single definite picture by Daniel Soreau existing. It is only possible to draw conclusions about how well the master passed on his artistic skills to his students through the works of his sons, other apprentices of his workshop and through Stoskopff's works. After Soreau's death in 1619, Stoskopff took over his workshop with the apprentices, as well as his function as the master. One of the apprentices was Joachim von Sandrart, who later became a successful painter and who wrote the first important work on the history of art in the German language: "Teutsche Academie der Bau-, Bild,- und Malerey- Kenste". This work contains descriptions of the lives of earlier and contemporary artists, including descriptions of the time in Hanau with his master, Sebastian Stoskopff. After his attempt to get permission to settle in Frankfurt failed, Stoskopff went to Paris. He stayed there from about 1622 until 1639, which can be reconstructed from indirect reports and property inventories of Parisians. His first works in larger format were also created here, such as "Summer" or "Winter" (now both in Strasbourg).
