He studied in Paris in successive stages over which he came to know the work of Courbet, the French Realists and the Barbizon school. In the end he even adapted to Impressionism. He is considered the best representative of Spanish Realism.. Leonardo Da Vinci
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.Vecchietta
Italian Early Renaissance Painter and Sculptor, ca.1410-1480
Italian painter, sculptor, goldsmith and architect. He was formerly believed to have been born c. 1412 in the Tuscan town of Castiglione d'Orcia, but del Bravo has identified him with the Lorenzo di Pietro di Giovanni who was baptized in Siena in 1410. His name appears in a list of the members of the Siena painters' guild in 1428. From the evidence of later works he is generally supposed to have been apprenticed to Sassetta, but his early work has not been identified. Between c. 1435 and 1439 he executed for Cardinal Branda Castiglione (1350-1443) a series of frescoes at Castiglione Olona, near Varese in Lombardy. He has been considered an assistant of MASOLINO DA PANICALE in this enterprise, but the scenes of the martyrdoms of SS Lawrence and Stephen in the apse of the Collegiata, below Masolino's vault frescoes, show that Vecchietta's closely packed compositional style was already fully formed. He also painted the frescoes (partially published by Bertelli) in the chapel of the Cardinal's palace in the town, depicting the Evangelists (vault) and friezes of male and female saints (side walls). Although abraded and fragmentary, they nevertheless indicate the naturalistic effects of atmospheric lighting and foreshortening that, more than any other Sienese painter of his day, he had learnt from Masolino and the Florentine painters.
