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 | The Virgin and Child with St Anne (detail) f | Annunciation (detail) st | Profile of an old man | The Adoration of the Magi |

The nidhi treasures Padma and Shankha stand besides him in human forms with their heads emerging from a lotus and a conch respectively. Agni Purana states that Kubera should be installed in temples as seated on a goat with club in his hand. Kubera's image is prescribed to be of gold with multi-coloured attributes
Rembrandt Peale
1778-1860 Rembrandt Peale Galleries Rembrandt Peale (February 22, 1778 ?C October 3, 1860) was a 19th century American artist that received critical acclaim for his portraits of presidents George Washington and Thomas Jefferson. Although modern art critics would consider Peale??s artwork as French neoclassical, its dark and stylized characteristics are similar to 15th and 16th century paintings. Rembrandt Peale was born the third of six surviving children (eleven had died) to his mother, Rachel Brewer, and father, Charles Willson Peale in Bucks County, Pennsylvania, on February 22, 1778. The father, Charles, also a notable artist, taught each child to paint scenery and portraiture, and Rembrandt was no exception. Charles tutored Rembrandt about the importance of having a strong mind from learning arts and sciences. At the age of eight, Rembrandt discovered drawing, and at thirteen, painted his first known self-portrait. Later on in his life, Rembrandt Peale "often showed this painting to young beginners, to encourage them to go from 'bad' to better..." like his steady progressions to become a successful portraitist. A year after his mother??s death and remarriage of his father, Rembrandt Peale left the school of the arts, thereby applying his time to completing his first ever self-portrait at the age of 13. The canvas illustrates early mastery of a young aspiring artist, seeming very mature. The clothes, however give the notion that Peale over-exaggerated what a 13 year old would look like. This style demonstrates early forms of neoclassicism by the looks of Peale's angel-like hair, the way it waves and curls in such a fashion so as to depict an angel from a general Renaissance artist's works of art. In July of 1787, Charles Willson Peale introduced his son Rembrandt to George Washington, where the young aspirant artist watched his father paint the remarkable figure of the country. In 1795, at the age of 17, Rembrandt painted an aging Washington, though the painter had depicted the politician as far more aged than the original facial characteristics. It did, nevertheless attain praise and Rembrandt had begun his debut. At the age of 20, Rembrandt married 22-year-old Eleanor May Short (1776-1836) at St. Joseph's Catholic Church in Philadelphia. During their marriage, Rembrandt and Eleanor had nine children: Rosalba, Eleanor, Sarah Miriam, Michael Angelo, and Emma Clara among them. In 1822, Peale moved to New York City where he embarked on an attempt to paint what he hoped would become the "standard likeness" of Washington. He studied portraits by other artists including John Trumbull, Gilbert Stuart and his own father, as well as his own 1795 picture which had never truly satisfied him. His resulting work Patriae Pater, completed in 1824, depicts Washington through an oval window, and is considered by many to be second only to Gilbert Stuart's iconic Athenaeum painting of the first president. Peale subsequently attempted to capitalize on the success of what quickly became known as his "Porthole" picture. Patriae Pater was purchased by Congress in 1832 and still hangs in the U.S. Capitol. Later on, Peale made over 70 detailed replicas of the same "father of our country", the first President of the United States. Peale continued to paint other noted portraits, such as those of the third president Thomas Jefferson while he was in office (1805), and later on a portrait of Chief Justice John Marshall.
