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 :. | Annunciation | The Virgin and Child with St Anne | Annunciation (detail) st | The last dinner | Interior view of the Schadels |

Paul Signac
1863-1935 French Paul Signac Galleries Paul Victor Jules Signac was born in Paris on November 11, 1863. He followed a course of training in architecture before deciding at the age of 18 to pursue a career as a painter. He sailed around the coasts of Europe, painting the landscapes he encountered. He also painted scenes of cities in France in his later years. In 1884 he met Claude Monet and Georges Seurat. He was struck by the systematic working methods of Seurat and by his theory of colours and became Seurat's faithful supporter. Under his influence he abandoned the short brushstrokes of impressionism to experiment with scientifically juxtaposed small dots of pure colour, intended to combine and blend not on the canvas but in the viewer's eye, the defining feature of pointillism. Many of Signac's paintings are of the French coast. He left the capital each summer, to stay in the south of France in the village of Collioure or at St. Tropez, where he bought a house and invited his friends. In March 1889, he visited Vincent van Gogh at Arles. The next year he made a short trip to Italy, seeing Genoa, Florence, and Naples. The Port of Saint-Tropez, oil on canvas, 1901Signac loved sailing and began to travel in 1892, sailing a small boat to almost all the ports of France, to Holland, and around the Mediterranean as far as Constantinople, basing his boat at St. Tropez, which he "discovered". From his various ports of call, Signac brought back vibrant, colourful watercolors, sketched rapidly from nature. From these sketches, he painted large studio canvases that are carefully worked out in small, mosaic-like squares of color, quite different from the tiny, variegated dots previously used by Seurat. Signac himself experimented with various media. As well as oil paintings and watercolours he made etchings, lithographs, and many pen-and-ink sketches composed of small, laborious dots. The neo-impressionists influenced the next generation: Signac inspired Henri Matisse and Andr?? Derain in particular, thus playing a decisive role in the evolution of Fauvism. As president of the Societe des Artistes Ind??pendants from 1908 until his death, Signac encouraged younger artists (he was the first to buy a painting by Matisse) by exhibiting the controversial works of the Fauves and the Cubists.
