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 the head | Study Fur the Trivulzio-monument | Landscape in the Arnotal | La belle Ferronire dg | Annunciation (detail) sg77 |

Calvaert, Denys
Flemish, 1540-1619 Flemish painter and draughtsman, active in Italy. In 1556-7 he was inscribed in the registers of the painters' corporation in Antwerp as a pupil of the landscape painter Kerstiaen van Queboorn (1515-78). Calvaert went to Bologna c. 1560, where he was to remain for the rest of his life. There he came under the protection of the influential Bolognini family and entered the workshop of Prospero Fontana the elder. After about two years he left Fontana to work with Lorenzo Sabatini, with whom he collaborated on several pictures, including the Holy Family with the Archangel St Michael (Bologna, S Giacomo Maggiore) and an Assumption (Bologna, Pin. N.). Calvaert's oeuvre is composed almost exclusively of religious works, ranging in size from vast altarpieces to small devotional pictures on copper. This sets him apart from other Netherlandish painters, notably those of the school of Prague, for whom Classical mythology was a constant source of inspiration. His first signed and dated work was Vigilance (1568; Bologna, Pin. N.); thereafter he developed a more original style, as in the Noli me tangere (Bologna, Pin. N.).

Ernest Hebert
1817-1908 French Ernest Hebert Gallery He was born in Grenoble and died in La Tronche. His painting Mal aria was exhibited in the Salon of 1850-1851, and now hangs in the Musee d Orsay, Paris. Painted in a Romantic style, it depicts a family of Italian peasants escaping an epidemic by raft, a scene inspired by events Hebert had witnessed while in Italy. His student Paul Trouillebert was an important artist of the Barbizon School. The artist house is preserved in the Musee Hebert in the VIe arrondissement of Paris. There is another museum near Grenoble.
