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 :. | The Adoration of the Magi | Salai as John the Baptist | Leda | Cecila Gallerani (mk45) | A rock gorge |

POST, Frans
Dutch Baroque Era Painter, 1612-1680 Painter and draughtsman, brother of Pieter Post. He was one of the first trained European landscape artists to paint in the New World. His paintings and drawings without exception depict Brazilian scenery with exotic buildings, plants, animals and natives. He probably received his early training from his father and was also influenced by his brother's early landscapes, although no works exist from this period. When Johan Maurits, Count of Nassau-Siegen went to Brazil as Governor General of the Dutch colony in the north-east in October 1636, Frans Post, together with ALBERT ECKHOUT, was among the artists and scientists on board to record various aspects of Brazilian life, landscape,
Simon de Vos
Simon de Vos (Antwerp, 20 October 1603-15 October 1676, Antwerp) was a Flemish Baroque painter of genre and cabinet pictures. De Vos studied with Cornelis de Vos (1603-76), to whom he is not related, from 1615 until 1620. In 1620 he joined Antwerp's guild of St. Luke, and then he probably travelled to Rome where he came under the influence of the "low-life" genre paintings of the Bentvueghels and the bambocciate. A Caravaggesque influence, by way of the German painter Johann Liss active in Italy during the 1620s is discernible in De Vos's paintings from this time on. In contrast to the earlier "low-life" paintings, works from the late 1620s until around 1640, which were made after returning to Antwerp, are mostly small "merry company" and courtly genre scenes reminiscent of contemporary Dutch painters Dirck Hals and Pieter Codde. After 1640, De Vos turned away from genre scenes altogether and painted mostly small cabinet paintings of history subjects, influenced stylistically at first by Peter Paul Rubens and then increasingly by Anthony van Dyck. Examples include The Beheading of St. Paul (1648) in the Royal Museum of Fine Arts, Antwerp. He married Catharina van Utrecht, the sister of Adriaen van Utrecht, in 1628.
