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 :. | Saint jean-Baptiste | Annunciation (detail) dg | The Baptism of Christ | Adoration of the Magi (mk08) | The Annunciation |

Sanford Robinson Gifford
1823-1880 Sanford Robinson Gifford (July 10, 1823 ?C August 29, 1880) was an American landscape painter and one of the leading members of the Hudson River School. Gifford's landscapes are known for their emphasis on light and soft atmospheric effects, and he is regarded as a practitioner of Luminism, an offshoot style of the Hudson River School. Returning to his studio in New York City, Gifford painted numerous major landscapes from scenes he recorded on his travels. Gifford's method of creating a work of art was similar to other Hudson River School artists. He would first sketch rough, small works in oil paint from his sketchbook pencil drawings. Those scenes he most favored he then developed into small, finished paintings, then into larger, finished paintings.
Juan de Valdes Leal
Seville 1622-1690 was a Spanish painter of the Baroque era. He was born at Seville in 1622, and distinguished himself as a painter, sculptor, and architect. He worked for a time under Antonio del Castillo. Among his works are a History of the Prophet Elias for the church of the Carmelites; a Martyrdom of St. Andrew for the church of San Francesco at Cerdoba; and a Triumph of the Cross for la Caridad at Seville. He was one of the founders of the Seville Academy along with his friend, Bartolome Esteban Murillo. He died at Seville. His wife (daughter of Antonio Palomino), Isabella Carasquilla, was also a painter. She died at Seville as late as 1730. Their children were artists, including Lucas, Juan, Maria, and Laura de Valdes. His daughters specialized in portrait miniatures.
Sebastien Bourdon
(2 February 1616 - 8 May 1671) was a French painter and engraver. His chef d'œuvre is The Crucifixion of St. Peter made for the church of Notre Dame. The Finding of Moses, c. 1650 (National Gallery of Art, Washington)Bourdon was born in Montpellier, France, the son of a Protestant painter on glass. He was apprenticed to a painter in Paris. In spite of his poverty he managed to get to Rome in 1636; there he studied the paintings of Nicolas Poussin, Claude Lorrain and Caravaggio among his eclectic selection of models, until he was forced to flee in 1638, to escape denunciation by the Inquisition for his Protestant faith. Bourdon's facility rendered him adept at portraiture, whether in a dashing Rubens manner or in intimate, sympathetic bust-length or half-length portraits isolated against plain backgrounds that set a formula for middle-class portraiture for the rest of the century, landscapes in the manner of Gaspar Dughet or cappricci of ruins, mythological "history painting" like other members of Poussin's circle or the genre subjects of the Dutch Bamboccianti who were working in Rome. His eclectic range of styles have given art historians exercise in tracing his adaptation of his models, while the lack of an immediately recognizable "Bourdon style" has somewhat dampened public appreciation. In 1652 Christina of Sweden made him her first court painter. Bourdon spent most of his working career outside France, where, though he was a founding member of the Academie de peinture et de sculpture (1648), he was for long largely dismissed as a pasticheur, a situation partly rebalanced by a comprehensive exhibition in 2000 of his work at the Musee Fabre, where the collection includes a fine Lamentation painted in the last years of his life. His success required the establishment of an extensive atelier, where, among his other pupils worked Nicolas-Pierre Loir and Pierre Mosnier. He died in Paris in 1671.
