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 :. | Madonna with the Yarnwinder | The Portinari Altarpiece | Mona Lisa | Leda | Virgin of th Rock (mk08) |

Pascal Adolphe Jean Dagnan-Bouveret
1852-1929 The popular French naturalist painter Pascal-Adolphe-Jean Dagnan-Bouveret is best known for his painstakingly detailed paintings of peasant scenes. Dagnan-Bouveret also created portraits and religious paintings. Pascal-Adolphe-Jean Dagnan was born in Paris on Jan. 7, 1852. His father moved to Brazil when he was 16, but he decided to stay in France with his mothers father. Later Dagnan-Bouveret added his grandfathers family name Bouveret to his own. Dagnan-Bouveret entered art school in Paris at age 17 and studied under the well-known academic painter Gerome. During this period Dagnan-Bouveret entered his paintings in several official competitions and placed highly in several. In 1878 Dagnan-Bouveret moved to the region known as the Franche-Comte, where he produced many landscapes and still life paintings. Dagnan-Bouveret won recognition in 1880 with his oil painting An Accident, which depicts a peasant boy with an injured hand visiting the doctor. Considered one of his finest paintings, it exemplifies Dagnan-Bouverets attempt to examine the psychology of his subjects through the use of well-rendered detail. Dagnan-Bouveret took advantage of new photographic technology to bring greater detail and heightened realism to his paintings. Dagnan-Bouveret used this technique especially in his paintings of peasants, such as Horses at the Watering Trough (1885). Dagnan-Bouveret was known to select people from his village, dress them in historical costumes, and then take photographs, which he then used with sketches as the basis of his paintings. By the 1890s his popularity as a portrait painter among wealthy patrons allowed him to explore more personal themes. Many of Dagnan-Bouverets later paintings, such as Supper at Emmaus (1896 C97), were religious in nature. Dagnan-Bouveret died in Quincey, Haute-Saone, France, on July 3, 1929.
Jean-Martial Fredou
Jean-Martial Fredou (28 January 1710 e 1795) was a French painter known for his portraits. Born at Fontenay-Saint-Pere, Fredou was attached to the Cabinet du Roi housed in the Hôtel de la Surintendance at Versailles, where he was commissioned to render duplicates of official portraits of the French royal family painted by Jean-Marc Nattier, Maurice Quentin de La Tour, Louis-Michel Van Loo, Alexander Roslin or Joseph Siffred Duplessis. In his own commissions he often borrowed elements from the original works of these painters, for he was a deft portraitist himself. Between 1760 and 1762 the dauphine Marie-Josephe de Saxe, daughter-in-law of Louis XV commissioned informal portraits of herself and her children, for her own use. These portraits, whether in oil or drawn aux trois crayons, touched with pastels, have freshness and life. A modest commission came from the Dauphin and Dauphine in 1757: in 1748 they had earth brought in to the little courtyard of their private apartments at the château de Versailles, closed in with trelliswork, to make a little garden; and Fredou was commissiomed to paint two perspective panels to enlarge the little space.[1] Fredou was never made a member of the Academie Royale de Peinture et de Sculpture, but he was made First Painter to the comte de Provence in 1776 upon the death of François-Hubert Drouais.
