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 :. | Study of the proportion of horses | Aurelio Luini attributed, profile of an old man | Lorenzo de Medici between Antonio Pucci and Francesco Sassetti, with Giulio de Medici, fresco by Ghirlandaio | Mona Lisa | Funf studies of grotesque faces |

(born June 1, 1878, Ledbury, Herefordshire, Eng. ?? died May 12, 1967, near Abingdon, Berkshire) English poet. He went to sea in his youth, then lived precariously for several years in the U.S. before settling in London. He is best known for his poems of the sea, Salt-Water Ballads (1902, including "Sea Fever" and "Cargoes"), and for his long narrative poems, such as The Everlasting Mercy (1911), containing phrases of colloquial coarseness that were unknown in earlier 20th-century English verse. After he became poet laureate in 1930, his poetry became more austere. He also wrote adventure novels, sketches, and works for children.
Pieter Aertsen
1508-1575 Flemish Pieter Aertsen Galleries Dutch painter and draughtsman, active also in the southern Netherlands. He probably trained in his native Amsterdam but early on moved to Antwerp, where he enrolled in the Guild of St Luke as a master in 1535. In 1542 he was granted citizenship of the city. Among his pupils in Antwerp were Johannes Stradanus and later Joachim Beuckelaer, a cousin of the artist wife and his most loyal follower. The earliest known work by Aertsen is a triptych with the Crucifixion (c. 1545-6; Antwerp, Maagdenhuismus.) for the van den Biest Almshouse in Antwerp. From 1550 Aertsen development can be traced through a large number of signed and dated paintings. Religious works, mostly intended for churches, must have formed an important part of Aertsen output. His early paintings seem to have been strongly influenced by other Antwerp artists, as can be seen in the van den Biest triptych, where the figures are close to those in Jan Sanders van Hemessen background scenes. Van Hemessen influence is also strong in the pair of triptychs showing the Seven Sorrows of the Virgin and the Seven Joys of the Virgin (the latter dated 1554; both Zoutleeuw, St Leonard).
