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 :. | The Madonna of the Carnation (detail) dg | Madonna of the Yarnwinder | Head of a girl | Head and shoulders Christs | Mona Lisa |

Apollonio di Giovanni
ca.1415-1465 Italian painter and illuminator. He was trained by illuminators in the circle of Bartolomeo di Fruosino and Battista di Biagio Sanguini (1393?C1451) and became a member of the Arte dei Medici e degli Speziali in 1442 and of the Compania di S Luca in 1443. Apollonio was influenced by Filippo Lippi, Lorenzo Ghiberti and Paolo Uccello.
Giovanni Battista Crespi
Giovanni Battista Crespi (23 December 1573 - 23 October 1632), called Il Cerano, was an Italian painter, sculptor, and architect. He was born in Romagnano Sesia, the son of a painter, Raffaele Crespi, and moved to Cerano with his family some years later. In 1591 he is known to have been living in Milan. True to the Counter-Reformation piety zealously expressed in Milanese art of his time, his paintings focus on mysteries and mystical episodes in saintly life. The crowded canvases and the angles recall Mannerism, but his paintings show an emotion that evokes common sentiments in Baroque art. Along with other artists, he completed a series of paintings (Quadroni of St. Charles) of the life of St. Charles Borromeo[1] for the Duomo of Milan, an altarpiece with the Baptism of St. Augustine for San Marco (Milan), and a Mass of St. Gregory for the Basilica of San Vittore in Varese (1615-17). Also see the nightmarish, St. Gregory Delivers the Soul of a Monk (1617), also in San Vittore.
KEIRINCKX, Alexander
Flemish painter (b. 1600, Antwerpen, d. 1652, Amsterdam). Flemish painter. He was the son of Matthijs Keirinckx and Anna Masson. In 1619 he became a master in Antwerp's Guild of St Luke, he married Clara Matthausen on 18 June 1622, and in 1624 he took on Artus Verhoeven as an apprentice. From 1636 onwards he is regularly recorded in Amsterdam, where he was registered as a citizen in the year of his death. He visited Great Britain, possibly in 1625 (Walpole mentions two signed and dated drawings of London views from this year) and definitely in 1640-41, when he undertook commissions from King Charles I to paint views of royal castles and palaces.
