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 :. | Muscle structure of the thigh | Study of an apostle | the last supper | Madchenkopf with confused hair | Mona Lisa |

Antonio Ponce
Spanish, 1608-1662,Spanish painter. He had an undistinguished career in Madrid as a painter of still-lifes and flower-pieces. In 1624 Ponce was apprenticed to Juan van der Hamen y Leen, whose niece he married in 1628. The format of Ponce's compositions and some of his motifs derive from works by van der Hamen, though lacking their subtlety of composition, spatial clarity and formal conviction. In Vase of Flowers, signed and dated 1650 (Strasbourg, Mus. B.-A.), Ponce's style shows laboured imitation of van der Hamen's: his dry execution results in a paradoxically airless and petrified quality. Ponce was always a derivative artist, and some of his still-lifes with seasonal themes are similar to works by Francisco de Barrera, another modest painter with whom he was documented in the 1630s. Paintings from the 1640s and 1650s depicting baskets of fruit and bunches of grapes against light backgrounds are characterized by compositional informality, softer lighting and freer brushwork, through which Ponce attempted to convey the textures of objects and endow the subject with greater naturalness.
Bonaventura Peeters
(Antwerp, 23 July 1614 - Hoboken (Antwerp), 25 July 1652) was a Flemish Baroque painter who specialized in seascapes and shipwrecks, known as Zeekens (small seascapes). Peeters, brother of the seascape painters Jan Peeters I, Gillis Peeters, and Catharina Peeters, learned to paint from his father, who became a master in Antwerp's guild of St. Luke in 1607 - 1608, and his earlier works are related to the tonal phase of Dutch landscape painting. Later paintings, however, reflect the stronger colors of Italianate classicism. This shift follows the general changes in artistic style at the time. Like his brother Jan, dramatic shipwrecks with dark billowy clouds, form a significant part of his oeuvre, as do serene ports and "portraits" of ships.Also, while many of Peeters's paintings reflect actual locations, and he may have even travelled along the coast of Scandinavia, his many views of far-away Mediterranean and Middle Eastern ports reflect a growing taste for the exotic and are probably inspired from fantasy and from prints. This tradition developed simultaneously in Flemish painting and in Dutch Golden Age painting, with many artists, including Peeters, working in both Antwerp and in the Dutch Republic.
