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 :. | Adoration of the Magi | Madonna Benois Madonna with a Flower | Saint John the Baptist | Virgin and Child with St Anne | The Last Supper-l |

Julius LeBlanc Stewart
(September 6, 1855, Philadelphia, Pennsylvania - January 5, 1919, Paris, France), was an American artist who spent his career in Paris. A contemporary of fellow expatriate painter John Singer Sargent, Stewart was nicknamed "the Parisian from Philadelphia." His father, the sugar millionaire William Hood Stewart, moved the family to Paris in 1865, and became a distinguished art collector and an early patron of Fortuny and the Barbizon artists. Julius studied under Eduardo Zamacois as a teenager, under Jean-Leo Grôme at the École des Beaux Arts, and later was a pupil of Raymondo de Madrazo. Stewart's family wealth enabled him to live a lush expatriate life and paint what he pleased, often large-scaled group portraits. The first of these, After the Wedding (1880), showed the artist's brother Charles and his bride Mae, daughter of financier Anthony J. Drexel, leaving for their honeymoon.
Severin Roesen
1848-1871 Severin Roesen (ca. 1815-1872) is a painter known for his abundant fruit and flower still lifes and is today recognized as one of the major American still-life painters of the mid-nineteenth century. Born in Cologne, in Germany, he emigrated to the United States in 1848. While Roesen's paintings reveal a meticulous attention to detail in their precise arrangements and close brushwork, his subject matter, even down to specific motifs, did not change throughout his career. Sometimes he made near copies of paintings, but usually he merely rearranged and reassembled stock elements. Numerous items in Fruit and Wine Glass, for example, also appear in other paintings. The footed desert plate full of strawberries is a common motif. The pilsner glass, sometimes accompanied by an open bottle of champagne, is interchangeable with a wine goblet filled with lemonade used elsewhere. The glass is nearly always placed at the lower left edge of the painting; a halved lemon often appears nearby. Branches full of grapes arranged from lower left to upper right provide the composition with a graceful S-curve and subtly lead the viewer's eye over the entire display. Here the composition is balanced by light and dark grapes at either side and filled in by scattered raspberries, cherries, peaches, apples, pears, and apricots. Many of these compositional elements, if not the items depicted, were derived from seventeenth-century Dutch still life paintings by such artists as Jan van Huysem.
