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.

Dutch painter and draughtsman. Boursse was the son of Walloon parents, Jacques Boursse and Anne de Forest. A testimony of 23 July 1658 states that Esaias brother Jan provided for his artistic training. There is nothing to confirm a view of the early 20th-century scholars Bode, Bredius and Valentiner that Boursse was a pupil of Rembrandt, although the two artists may have had some contact, since Rembrandt lived near Jan in Amsterdam. According to an inventory of 24 November 1671, Jan collected a number of paintings, drawings and etchings by Rembrandt.Jan Both
Jan Dirksz Both (between 1610 and 1618 - August 9, 1652) Jan Both was a Dutch painter, draughtsman, and etcher, who made an important contribution to the development of Dutch Italianate landscape painting.
Both was born in Utrecht, and was the brother of Andries Both. According to Houbraken, the brothers first learned to paint from their father, who was a glass-painter or glazier there. Later Jan was a pupil of Abraham Bloemaert and still later the brothers traveled together to Rome via France. Gerrit van Honthorst has also been suggested as a teacher.
By 1638 Jan and his brother Andries were in Rome where Andries concentrated on genre works in the manner of Pieter van Laer, while Jan concentrated on landscapes in the manner of Claude Lorrain. In 1639 Jan collaborated with Herman van Swanevelt and Claude Lorrain on a project for the Buen Retiro Palace in Madrid. Certainly by 1646 Jan had returned to Utrecht, where he refined further his expansive, imaginary landscapes drenched with a Mediterranean golden light. In Landscape with Bandits Leading Prisoners (Museum of Fine Arts, Boston) the sandy road makes a sweeping diagonal from the left. Touches of realism in the down-to-earth figures and detailed vegetation of the foreground contrast with the idyllic golden distance. Occasionally Both peoples his landscapes with religious or mythological figures as in Judgement of Paris (London, National Gallery) where the figures were painted by a fellow Utrecht artist, Cornelis van Poelenburch. Jan's brother Andries (c.1612-41), who specialised in peasant scenes, died in Venice as they were returning to Utrecht.LEICHER, Felix Ivo
