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 :. | Abendmahl | Madonna and Child with St Anne and the Young St John | Kvinnoportratt | Study fur the Sforza-Reiterstandbild | Studies fur the adoration of the Konige |

Pieter Jansz. Saenredam
(June 9 1597 - buried May 31 1665) was a painter of the Dutch Golden Age, known for his distinctive paintings of whitewashed church interiors. Saenredam was born in Assendelft, the son of the Northern Mannerist printmaker and draughtsman Jan Pietersz Saenredam (1565-1607), a follower of Goltzius whose sensuous naked goddesses are in great contrast with the work of his son. In 1612 he moved to Haarlem, where he became a pupil of Frans de Grebber and lived for the rest of his life. In 1614 he became a member of the Haarlem Guild of St. Luke. He died in Haarlem. A contemporary of the painter-architects Jacob van Campen, Salomon de Bray, and Pieter Post, he is noted for his surprisingly modern paintings of church interiors, the great bulk of his production. Saenredam achieved this modern look by using very even light, subtlely modulated, and by removing detailed depiction of textures, in meticulously measured and drawn sketches. He would make these sketches in pencil, pen, and chalk, then and add in watercolor to help give the sketch texture and color. The sketches are detailed, conveying the interior atmosphere through the clever use of light and graduated shadows. Saenredam often deliberately omitted people and church furniture from work, thus focusing more attention on buildings and their architectural forms. Only after having made precise measurements, and precise sketches and drawings of the churches, he would take them to his studio where he started to create his paintings, often after a delay of many years. His emphasis on even light and geometry is brought out by comparing his works with those of the rather younger Emanuel de Witte, who included people, contrasts of light and such clutter of church furniture as remained in Calvinist churches, all usually ignored by Saenredam. Unlike de Witte's, Saenredam's views are usually roughly aligned with a main axis of the church.
seraphine
Seraphine Louis, known as "Seraphine de Senlis" ("Seraphine of Senlis") (1864?C1942), was a French painter in the naïve style. Self-taught, she was inspired by her religious faith and by stained-glass church windows and other religious art. The intensity of her images, both in color and in replicative designs, are sometimes interpreted as a reflection of her own psyche, walking a tightrope between ecstasy and mental illness.
