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 :. | Madonna of the Rocks | The Madonna of the Carnation | The Annunciation | Cartoon | La Gioconda (The Mona Lisa) |

Leonaert Bramer
(24 December 1596 - 10 February 1674 (buried)) was a Dutch painter, best known for probably being one of the teachers of Johannes Vermeer, although there is no similarity between their work. Bramer's dark and exotic style is unlike Vermeer's style. Bramer was primarily a genre and history painter, but also made some unique frescos, not very often found north of the Alps. Leonaert Bramer is one of the most intriguing personalities in seventeenth-century Dutch art. He was a talented and diligent draughtsman, evidently Roman Catholic and a lifelong bachelor. Bramer was born in Delft. In 1614, at the age of 18, he left on a long trip eventually reaching Rome in 1616, via Atrecht, Amiens, Paris, Aix (February 1616), Marseille, Genoa, and Livorno. In Rome he was one of the founders of the Bentvueghels group of Northern artists. He lived with Wouter Crabeth and got into a fight with Claude Lorraine. He dedicated a poem to Wybrand de Geest. Bramer remained on and off in Rome until October 1627, visiting Mantua and Venice, often for deliveries and to meet Domenico Fetti. In Italy Bramer was nicknamed Leonardo della Notte ("Leonardo of the night"). In 1648 he went to Rome for a second time. By 1628 he was back in Delft, where he joined the Guild of Saint Luke in 1629 and the schutterij. Among his many patrons were members of the House of Orange, but local burgomasters and schepen also bought his paintings in great numbers.[3] He was a many sided artist, designing for tapestry firms in Delft, painting murals and ceilings, some of which are illusionistic in style. He painted real frescos in the Civic Guard house, the nearby stadholder's palaces in Honselersdijk, Rijswijk, the Communal Land Housde and the Prinsenhof in Delft.[3] Due to the Dutch climate they no longer survive. He evidently knew the greatest of his Delft contemporaries, Johannes Vermeer, as he came to the latter's defence when his future mother-in-law was trying to prevent him from marrying her daughter.
