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 :. | Raffaello Sanzio named Raffael Portrat of Lorenzo de Medici | Unfinished painting of St. Jerome in the Wilderness | Mona Lisa (mk45) | Master of the Pala Sforzesca, profile of an old man | Madonna with the Yarnwinder |

Italian High Renaissance Painter, 1472-1517, also known as Baccio della Porta, was an Italian Renaissance painter of religious subjects. He was born in Savignano di Prato, Tuscany. He received the nickname of Baccio della Porta for his house was near the Porta ("Gate") San Pier Gattolini. Starting from 1483 or 1484, by recommendation of Benedetto da Maiano, he apprenticed in the workshop of Cosimo Rosselli. In 1490 or 1491 he began a collaboration with Mariotto Albertinelli. In the late 1490s Baccio was drawn to the teachings of Fra Girolamo Savonarola, who denounced what he viewed as vain and corrupt contemporary art. Savonarola argued for art serving as a direct visual illustration of the Bible to educate those unable to read the book. From 1498 is his famous portrait of Savonarola, now in the Museo Nazionale di San Marco in Florence. The following year he was commissioned a fresco of the Universal Judgement for the Ospedale di Santa Maria Nuova, completed by Albertinelli and Giuliano Bugiardini when Baccio became a Dominican friar on July 26, 1500. The following year he entered the convent of San Marco. He renounced painting for several years, not resuming until 1504 when he became the head of the monastery workshop in obedience to his superior. In that year he began a Vision of St. Bernard for Bernardo Bianco's family chapel in the Badia Fiorentina, finished in 1507.
