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 :. | Madonna in the rock grottos(Details | Last Supper (mk08) | Leda | Mona Lisa | Annunciation (detail) sg77 |

JACOBSZ, Dirck
Flemish Northern Renaissance Painter, ca.1497-1567 North Netherlandish painter, son of JACOB CORNELISZ. VAN OOSTSANEN. His birthdate is estimated from van Mander's claim that he died at the age of almost 70. His birthplace is unknown, but by about the age of three he was living in Amsterdam, where his father purchased a house in 1500. Dirck himself is documented in the city from 1546 until his burial. About 1550 he married Marritgen Gerritsdr., by whom he had two children, Maria Dircksdr. and Jacob Dircksz. War, also a painter. Dirck was trained by his father, probably around 1512, when Jan van Scorel was an apprentice. The two young artists may have remained friends, for in later years elements of Jan's mature, more Mannerist style can be seen in Dirck's paintings. Not only were Dirck's father and his brother, the little-known painter Cornelis Jacobsz. (d 1526-33), artists, his uncle Cornelis Buys I ( fl c. 1490-1524)
th. hildebrandt
Ferdinand Theodor Hildebrandt, född 2 juli 1804 i Stettin, död 29 september 1874 i Dusseldorf, var en tysk målare. Hildebrandt började sina konstnärliga studier i Berlin under Wilhelm Schadow, vilken han 1826 följde till Dusseldorf, och blev en av den där grundade skolans mest framstående lärjungar. 1825 framträdde han med Faust, 1826 med Cordelia och kung Lear och 1828 med Tankred döpande Klorinda. Ännu större popularitet vann han 1835 för Mordet på kung Edvards söner. Bland hans genrebilder har i synnerhet Krigaren och hans son (1832, Berlins nationalgalleri) blivit känd. Hildebrandt, som för övrigt utförde illustrationer och porträtt, kallades på sin tid realist, men han var knappast fri från den melodramatiska ton och den sentimentala inställning, som tillhörde skolan.
Evert Oudendijck
(1650, Haarlem - 1695, Haarlem), was a Dutch Golden Age painter. According to Houbraken he painted stag hunts and other hunting scenes in landscapes, along with the artist "Drossaart". He was the father of Adriaen Oudendijck. According to the RKD he was registered in the Haarlem Guild of St. Luke in 1663 as the pupil of Adriaen van Ostade which would make him about 15 years old at that time.His registration as a member of the guild in 1646 is therefore impossible. Though Evert Oudendijk is listed in the Haarlem guild register as a member in 1646, he probably became a member in 1664 (a year suspiciously lacking member registrations), like other members mistakenly registered in 1646, such as Evert Collier and Egbert van Heemskerck. He is listed two other times in the Haarlem guild; in 1663 (listed as Ostade's pupil "Evert Adriaanszen van Oudendijck") and as painter in 1670.
