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 an apostle | Mona Lisa | Reverse side of the portrait of Ginevra de' Benci | Mona Lisa (La Gioconda) sdg | Interior view of the Schadels |

Jacob Gerritsz. Cuyp
was a portrait and landscape painter. He was born and died in Dordrecht, and was the half-brother of Benjamin Gerritsz Cuyp and the father of the much more famous Aelbert Cuyp. According to Houbraken, he helped the painters Jacques de Claeuw, Isaac van Hasselt, and Cornelis Tegelberg set up a Guild of Saint Luke in Dordrecht in 1642.
CERQUOZZI, Michelangelo
Italian Baroque Era Painter, ca.1602-1660 Italian painter. He was a painter of bambocciate (low-life subjects), battles, small religious and mythological works and still-lifes. He was born of Roman parents, baptized in the parish of S Lorenzo in Lucina and spent his entire life in his native city. A member of the Accademia di S Luca since 1634, Cerquozzi attended meetings of the society as late as 1652. His friends included Domenico Viola, Pietro da Cortona and Giacinto Brandi. More significant were his associations with foreign residents in Rome. According to Baldinucci, Cerquozzi had special affection for the Spanish, owing to the patronage he received from the major-domo of the Spanish Embassy as a youth, and would often don Spanish attire as a sign of his sentiment. His Spanish connections may partly account for the many commissions he later received from patrons identified with Rome's pro-Spanish political faction (Haskell). Cerquozzi enjoyed equally good rapport with northern European residents of Rome. He is documented as having quartered with artists from beyond the Alps, including Paulus Bor and Cornelis Bloemaert, for the bulk of his career.
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.
