LEONARDO da Vinci
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.
Alexander Keirincx
Alexander Keirincx (Antwerp, 23 January 1600-Amsterdam, 1652) was a Flemish Baroque painter who spent his later career in the Dutch Republic. He became a master in Antwerp's guild of St. Luke in 1619, and like his teacher Abraham Govaerts he initially specialized in small cabinet-sized forest landscapes in the manner of Jan Brueghel the Elder and Gillis van Coninxloo. Also like Govaerts, Keirincx's early works typically show diminutive history, mythological or biblical subjects within a Mannerist three-color universal landscape bracketed by repoussoir trees. However, during the 1620s his landscapes become increasingly natural. He lived in Utrecht and Amsterdam from 1628 until the end of his career, and made trips to England to decorate palaces for Charles I. The figures in his works were usually painted by collaborators such as Cornelis Poelenburg.[1] Keirincx worked primarily as an art dealer later in life.
Henri Testelin
(Paris, 1616 - The Hague, 1695) was a French art painter. Henri Testelin made portraits of Louis XIV, important persons and events at the French court . Several of his paintings can be seen in the palace of Versailles. The portraits, like the one of the young Louis XIV, show the influence of Jean Nocret and Le Brun. He was secretary of Royal Academy of Painting and Sculpture from 1650 and professor from 1656. In 1680 he published a book on art theory and the academy. Testelin was dismissed from the Academy in 1681, because he was proptestant. He left France and went to Holland.
