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 :. | Our Lady and St Anne | The adoration of the Konige | Mona Lisa | Portrats of two men | Leda |

Ralph Albert Blakelock
(October 15, 1847 - August 9, 1919) was a romanticist painter from the United States. Ralph Blakelock was born in New York City on October 15, 1847. In 1864, Blakelock entered the Free Academy of the City of New York (now known as the City College) with aspirations of becoming a physician. After his third term he opted to dismiss his formal education and left college. From 1869-71 he traveled west, extensively wandering far from known civilization and spending time among the American Indians. Largely self-taught as an artist, he began producing competent landscapes, depicting select views from his travels, as well as scenes of American Indian life. His works were exhibited in the National Academy of Design. Moonlight, 1885, the Brooklyn MuseumIn 1877 Blakelock married Cora Rebecca Bailey; they had nine children. In art, Blakelock was a genius, yet, in business dealings and in monetary transactions he proved a failure. He found it difficult, if not crushing to maintain and support his wife and children. In desperation he found himself selling his paintings for extremely low prices, far beneath their known worth. In hopes of lifting his family from abject poverty, reportedly on the day his 9th child was born, Blakelock had offered a painting to a collector for $1000. The collector made a counter offer and after refusing the proposed sum Blakelock found himself in a bitter argument with his wife. After the domestic dispute, Blakelock returned to the patron and sold the painting for a much lesser sum. Defeated and frustrated, it is said he broke down and tore the cash into pieces. And so it was after such repeated failed business transactions that he began to suffer from extreme depression and eventually show symptoms of mental frailty. In 1899 he suffered a breakdown.
James Baker Pyne
English Painter, 1800-1870 He was articled to a Bristol attorney, but around 1821 he took up painting and exhibited at the Bristol Gallery of Arts in 1824. Apparently self-taught, he worked closely with the Bristol artist Samuel Jackson (1794-1869) for a time and was influenced by the poetic landscapes of Francis Danby. In 1835 he moved to London and exhibited at the Royal Academy the following year. He showed seven pictures there altogether, but he also exhibited at the British Institution and showed 206 works at the Society of British Artists. Although technically accomplished, Pyne's work is curiously lacking in distinction. He imitated many artists but never found a style of his own. His early views of Bristol are among his best work, a good example being View of the Avon from Durdham Down (1829; Bristol, Mus. & A.G.). He also painted some lively coast scenes such as Whitby (Leicester, Mus. & A.G.). He was less successful when emulating J. M. W. Turner.
Emanuel de Witte
(1617 - 1692) was a Dutch perspective painter. In contrast to Pieter Jansz Saenredam, who emphasized architectural accuracy, De Witte was more concerned with the atmosphere of his interiors. Though few in number, de Witte also produced genre paintings. De Witte was born in Alkmaar and learned geometry from his father, a schoolmaster. He joined the local Guild of St Luke in 1636. After a stay in Rotterdam, he moved to Delft and studied with Evert van Aelst. In 1651 de Witte settled in Amsterdam where his first wife, Geerje Arents, died in 1655. He then married a 23-year-old orphan, Lysbeth van der Plas, who exercised a bad influence on de Witte's adolescent daughter. In December 1659 both were arrested for theft from a neighbor.Lysbeth, pregnant, had to leave the city for a period of six years; she lived outside the city walls and died in 1663. Following the arrest of his wife and child, de Witte was forced to indenture himself to the Amsterdam notary and art dealer Joris de Wijs, surrendering all of his work in exchange for room, board, and 800 guilders annually. De Witte broke the contract, was sued by the dealer, and forced to indenture himself further as a result. Several patrons provided de Witte with support, but these relations did not work out well, for he tended to shout at his clients and at people watching him at work in churches. Records tell of his gambling habit and a fight with Gerard de Lairesse. According to Arnold Houbraken, after an argument about the rent, de Witte hanged himself from a canal bridge in 1692. The rope broke and de Witte drowned. Because the canal froze that night, his corpse was not found until eleven weeks later
