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 Virgin and Child with St Anne ey | Madonna in the rock grottos | Funf studies of grotesque faces | Lady with the ermine | Madonna with a Flower |

Floris van Dijck
Dutch Baroque Era Painter, 1575-1651 Dutch painter and draughtsman. He is thought to have been a pupil of Rembrandt in Amsterdam c. 1650. There is no documentary evidence for this, but his earliest dated painting, the Presentation in the Temple shows that he had certainly seen examples of Rembrandt work. He was an eclectic artist, given to following several models simultaneously. This is evident from two versions of Elijah and the Widow of Zarephath; one (1655-60; Copenhagen, Stat. Mus. Kst) is painted in horizontal format in the style of Barent Fabritius, while the other (1655-60; Milwaukee, WI, A. Bader priv. col., see Sumowski, 1983, no. 362) features large half-length figures in the manner of Nicolaes Maes. In another biblical scene, Benjamin and Judah (1655-60; Chicago, IL, A. Inst.), he followed the example of Rembrandt. His best works, such as Saying Grace (1655-60; Hannover, Nieders?chs. Landesmus.) and the Old Prophetess (1655-60; Leipzig, Mus. Bild. Kst), show old women either praying or sleeping and confirm that Maes was his main source of inspiration. Similar subjects are represented in the drawings attributed to him (e.g. Old Woman Seated, Holding a Book; New York, Pierpont Morgan Lib.). In the late 1650s van Dijck also seems to have been influenced by the genre paintings of Gabriel Metsu and above all by Quiringh van Brekelenkam, as in Hermit Praying in a Cave (late 1650s; St Petersburg, Hermitage) and Family Saying Grace (late 1650s; Stockholm, Nmus.).
