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 :. | Profile of an old man | Anatomy of the Schadels | Madonna Litta (detail sdg | Madonna with the Yarnwinder ty | Self Portrait |

Gerrit van Honthorst
1590-1656 Dutch Gerrit Van Honthorst Galleries Gerard van Honthorst (November 4, 1592 - April 27, 1656), also known as Gerrit van Honthorst and Gherardo della Notte, was a Dutch painter of Utrecht. He was brought up at the school of Abraham Bloemaert, who exchanged the style of the Franckens for that of the pseudo-Italians at the beginning of the 16th century. Margareta Maria de Roodere and Her Parents by Gerrit van Honthorst (1652) Oil on canvas, 140 x 170 cm. Centraal Museum, UtrechtInfected thus early with a mania which came to be very general in the Netherlands, Honthorst went to Italy in 1616, where he copied the naturalism and eccentricities of Michelangelo da Caravaggio. Home again about 1620, after acquiring a considerable practice in Rome, he set up a school at Utrecht which flourished exceedingly. Together with his colleague Hendrick ter Brugghen, he represented the so-called Dutch Caravaggisti. In 1623 he was president of his gild at Utrecht, where he had married his cousin. He soon became so fashionable that Sir Dudley Carleton, then English envoy at The Hague, recommended his works to the earl of Arundel and Lord Dorchester. In 1626 he received a visit from Rubens, whom he painted as the honest man sought for and found by Diogenes. The queen of Bohemia, sister of Charles I of England and electress palatine, being in exile in the Netherlands, gave Honthorst her countenance and asked him to teach her children drawing; and Honthorst, thus approved and courted, became known to her brother Charles I, who invited him to England in 1628. There he painted several portraits, and a vast allegory, now at Hampton Court, of Charles and his queen as Diana and Apollo in the clouds receiving the duke of Buckingham as Mercury and guardian of the king of Bohemia's children. Charles I, whose taste was flattered alike by the energy of Rubens and the elegance of Van Dyck, was thus first captivated by the fanciful mediocrity of Honthorst, who though a poor executant had luckily for himself caught, as Lord Arundel said, much of the manner of Caravaggio's colouring, then so much esteemed at Rome.
Casilear John William
American Hudson River School Painter, 1811-1893 was an American landscape artist belonging to the Hudson River School. Casilear was born in New York City. His first professional training was under prominent New York engraver Peter Maverick in the 1820s, then with Asher Durand, himself an engraver at the time. Casilear and Durand became friends, and both worked as engravers in New York through the 1830s. By the middle 1830s Durand had become interested in landscape painting through his friendship with Thomas Cole. Durand, in turn, drew Casilear's attention to painting. By 1840 Casilear's interest in art was sufficiently strong to accompany Durand, John Frederick Kensett, and artist Thomas P. Rossiter on a European trip during which they sketched scenes, visited art museums, and fostered their interest in painting. Casilear gradually developed his talent in landscape art, painting in the style that was later to become known as the Hudson River School. By the middle 1850s he had entirely ceased his engraving career in favor of painting full-time. He was elected a full member of the National Academy of Design in 1851, having been an associate member since 1831
John Hoppner
1758-1810 British John Hoppner Galleries John Hoppner (April 4?, 1758 - January 23, 1810), English portrait-painter, was born in Whitechapel. His father was of German extraction, and his mother was one of the German attendants at the royal palace. Hoppner was consequently brought early under the notice and received the patronage of George III, whose regard for him gave rise to unfounded scandal. As a boy he was a chorister at the royal chapel, but showing strong inclination for art, he in 1775 entered as a student at the Royal Academy. In 1778 he took a silver medal for drawing from the life, and in 1782 the Academy's highest award, the gold medal for historical painting, his subject being King Lear. He first exhibited at the Royal Academy In 1780. His earliest love was for landscape, but necessity obliged him to turn to the more lucrative business of portrait painting. At once successful, he had throughout life the most fashionable and wealthy sitters, and was the greatest rival of the growing attraction of Lawrence. Ideal subjects were very rarely at tempted by Hoppner, though a "Sleeping Venus," "Belisarius," "Jupiter and Io," a "Bacchante" and "Cupid and Psyche" are mentioned among his works. The prince of Wales visited him especially often, and many of his finest portraits are in the state apartments at St. James's Palace, the best perhaps being those of the prince, the duke and duchess of York, of Lord Rodney and of Lord Nelson, Among his other sitters were Sir Walter Scott, the Duke of Wellington, Frere and Sir George Beaumont. Competent judges have deemed his most successful works to be his portraits of women and children. A Series of Portraits of Ladies was published by him in 1803, and a volume of translations of Eastern tales into English verse in 1805. The verse is of but mediocre quality. In his later years Hoppner suffered from a chronic disease of the liver. He was confessedly an imitator of Reynolds. When first painted, his works were much admired for the brilliancy and harmony of their colouring, but the injury due to destructive mediums and lapse of time which many of them suffered caused a great depreciation in his reputation. The appearance, however, of some of his pictures in good condition has shown that his fame as a brilliant colourist was well founded. His drawing is faulty, but his touch has qualities of breadth and freedom that give to his paintings a faint reflection of the charm of Reynolds. Hoppner was a man of great social power, and had the knowledge and accomplishments of a man of the world. The best account of Hoppner's life and paintings is the exhaustive work by William McKay and W Roberts (1909
