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 :. | Mona Lisa | the last supper | Portrats of two men | The Benois Madonna | Profile of an old man |

Lev Feliksovich Lagorio
(Russian: 1828-1905) was a Russian painter, known for his paintings of seascapes. Lagorio was born in Feodosia, Crimea (now Ukraine) and later studied in the Imperial Academy of Arts in Saint Petersburg. His teachers were Maxim Vorobiev and B. P. Villeval'de. While he lived in Feodosia, he was influenced by the painter Ivan Aivazovsky. In 1845 Lagorio went on a sea voyage on the warship Groziashchy to study the arrangement of the ship. Lagorio spent eight years in Italy. The paintings he created there brought him to the status of professor on his return home to Russia. In his later years, he painted the coastal views of Finland and Norway. He also painted motives of the Russian-Turkish war.
Jan josephsz van goyen
Dutch , Leyden 1596-The Hague 1656 was a Dutch landscape painter. Van Goyen was an extremely prolific artist; approximately twelve hundred paintings and more than one thousand drawings by him are known. Jan van Goyen was the son of a shoemaker and started as an apprentice in Leiden. Like many Dutch painters of his time, Jan van Goyen studied art in the town of Haarlem with Esaias van de Velde. At age 35, he established a permanent studio at Den Haag (The Hague). Crenshaw tells (and mentions the sources) that Van Goyen's landscape paintings rarely fetched high prices, but he made up for the modest value of individual pieces by increasing his production, painting thinly and quickly with a limited palette of inexpensive pigments. Despite his market innovations, he always sought more income, not only through related work as an art dealer and auctioneer but also by speculating in tulips and real estate. Although the latter was usually a safe avenue of investing money, in Van Goyen's experience it led to enormous debts. Paulus Potter rented one of his houses. Nicolaes van Berchem became his pupil. In 1652 and 1654 he was forced to sell his collection of paintings and graphic art, and he subsequently moved to a smaller house. He died in 1656, still unbelievably 18,000 guilders in debt, forcing his widow to sell their remaining furniture and paintings.
