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 :. | la scapigliata | The embryo in the Uterus | The Benois Madonna | You branching of the Blutgefabe, anatomical figure with heart kidneys and Blutgefaben | Portrat of a Madchens |

marin mersenne
French mathematician,philosopher and theorist. One of the leading French thinkers of the 17th century, he lived in Paris from 1619 as a Jesuit priest. His work is central to the academic and scientific movements of his time, and a major part of it is devoted to music. On the basis of practical experiment and observations, he made important discoveries concerning the nature and behaviour of sound, which are the foundation of the science of acoustics in later times. He also wrote on the theory and practice of music. His principal musical treatise is the Harmonie universelle

COLLANTES, Francisco
Spanish Baroque Era Painter, 1599-1656 Spanish painter. He was probably a pupil of Vicente Carducho, but there is nothing to support this idea. His evident familiarity with contemporary Italian art indicates that he visited Rome and Naples, and this might explain the absence of documentation on him in Spain. Collantes enjoyed considerable prestige, and his paintings were acquired in 1634 for the decoration of the Buen Retiro Palace in Madrid; some of them may have been specially painted for this setting. His name appears frequently in the inventories of collectors in Madrid throughout the 17th century. It is impossible to date Collantes's undated paintings with any accuracy. However, his work shows two very clear and different lines of development. His canvases of large, intensely naturalistic figures, with tenebrist lighting effects , are close in style to those of Jusepe Ribera. In them the intense, energetic figures are sometimes set against landscape backgrounds, for example in St Humphrey (1645-50; Madrid, Prado) and St John the Baptist , but, still following Ribera, the naturalistic elements are emphasized. He also specialized in landscapes and in biblical or mythological subjects, compositions with minute figures set against wide landscapes or architecture with strong light effects. These are the works for which he is best known and which are the most important, since he was one of the few landscape painters in Spain in the 17th century.
