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 :. | Detail of Madonna of the Rocks | The Annunciation-o | Adoration of the Magi | Detail of Madonna of the Rocks | The Last Supper-l |

Nardo di Cione
Italian Byzantine Style Painter, active 1343-ca.1365 was an Italian painter, sculptor and architect from Florence. He was the brother of the more accomplished Andrea di Cione, called Orcagna, as well as Jacopo di Cione; they were important members of the Painter's Guild of Florence. While Orcagna has been noted as the more accomplished artist, Nardo developed his own unique style, described as a pronounced lyrical vein, a feeling for poetic values, strong human sympathies and great sensitivity to colour as a means of subtle differentiation and soft modeling. The brothers collaborated on a number of works from their studio together, including the decorations from the Cappella Strozzi in the Santa Maria Novella. While Orcagna painted the altarpiece, Nardo executed the frescoes of The Last Judgment, Paradise and Hell.
Adriaen Van Utrecht
Flemish Baroque Era Painter, 1599-1652 Flemish painter. He was apprenticed to Herman de Ryt in 1614 and later visited France, Italy and Germany before returning to Antwerp by 1625. He painted pantry scenes, farmyards with poultry, fish markets, game pieces, garlands and diverse still-lifes of fruit and vegetables. Game paintings are most frequent and reflect the influence of Frans Snyders. Adriaen adopted the same abundant displays of game, fruit and vegetables, usually set on a table parallel to the picture plane. Compositions typically fall in horizontal and vertical lines in contrast to the dynamic diagonals of Snyders. In large works, such as the Still-life with Game, Vegetables, Fruit and a Cockatoo (1650; Malibu, CA, Getty Mus.), Adriaen's accessories overflow the table on to the floor below. Baroque devices, such as a sweeping curtain and background window view, add movement and depth. Van Utrecht favoured warm earthen tones, especially grey-green, and a strong chiaroscuro light in his still-lifes; the latter may derive from his knowledge of Italian painting. The artist's style changed little during his career, save for the gradual elimination of figures in his paintings. The influence of Jan de Heem and Jan Fyt can also be seen in his later work.
