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 :. | Adoration of the Magi | Horses with horsemen | The Annunciation-o | Portrait of Ginerva de'Benci | Portrait of Ginerva de'Benci-u |

David van der Plas
David van der Plas (1647-1704), was a Dutch Golden Age portrait painter. David van der Plas became famous as a portrait painter, and his most illustrious patron was Cornelis Tromp. In 1684 he married Cornelia van der Gon of Haarlem, the daughter of the castellan (kastelein) of the Oude Doelen, the meeting quarters of the Haarlem schutterij (the building currently houses the Stadsbibliotheek Haarlem). David van der Plas' brother-in-law was the painter Govert van der Leeuw and his pupil was Jacob Appel. His wife Cornelia van der Gon was the rich heiress of the Amsterdam architect Adriaan Dortsman (ca. 1636-1682), who designed the round Lutheran church on the Singel. The marriage was childless, and Cornelia spent her time on her doll houses, which Dortsman had helped design and which Van der Plas helped decorate. The landscape painter Jan Wijnants also painted miniatures for these doll houses. Cornelia died in 1701, and after the death of Van der Plas, the doll houses were sold at auction to Sara Rothe, who used them to decorate her own doll houses.
rudolph von alt
Rudolf Ritter von Alt (28 August 1812 in Vienna ?C 12 March 1905 in Vienna) was an Austrian landscape and architectural painter. Borne as Rudolf Alt, he could call himself von Alt and bear the title of a Ritter (knight) after he gained nobility in 1882. He was the son of the famous lithographer Jakob Alt (1789-1872). He studied at the Akademie der bildenden K??nste in Vienna. Hiking-trips through the Austrian Alps and northern Italy awoke a love for landscapes, and he painted with his brush using watercolors in a very realistic and detailed style. In 1833, inspired by a visit to Venice and neighbouring cities, he also made a number of architectural paintings. Alt demonstrated a remarkable talent for expressing certain peculiarities in nature. He managed to paint nature authentically by focusing on the different hues of sky, the colour-tone of the air and the vegetation. His later works came closer to Impressionism. His perspectives on architecture were interesting, and he often chose everyday objects to paint. The painting of interior-views also became one of his strong points, giving him attention in Vienna. He visited and worked for a while in Rome and Naples; after that he visited the lakes of Lombardy, then Galicia, Bohemia, Dalmatia, Bavaria and then returned multiple times to Italy. In 1863 he went to the Crimea to paint some views of an estate of the Empress, and in 1867 he went to Sicily. His younger brother Franz Alt, (b. 1821 in Vienna) was also a painter. Most of his paintings are held by various museums in Vienna. The Albertina in Vienna hosted a retrospective exhibition from September 2005 to January 2006.
Jules Tavernier
1844-1889 Jules Tavernier was born in Paris in 1844. He studied with the French painter, F??lix Joseph Barrias (1822-1907), but left France in the 1870s, never to return. Tavernier was employed as an illustrator by Harper's Magazine, which sent him on assignment to California in the 1870s. Eventually he continued westward to Hawaii, where he made a name for himself as a landscape and portrait painter. He was captivated by Hawaii??s erupting volcanoes??a subject that was to pre-occupy him for the rest of his life, which was spent in Hawaii, Canada and the western United States. He is considered the most important artist of Hawaii??s Volcano School. Tavernier died in Honolulu, Hawaii in 1889. His students included David Howard Hitchcock (1861-1943), Am??d??e Joullin (1862-1917), Charles Rollo Peters (1862-1917) and Manuel Valencia (1856-1935). The Honolulu Academy of Arts and the Stark Museum of Art (Orange, Texas) are among the public collections having paintings by Jules Tavernier.
