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 | Study of the proportion of the head | Mona Lisa | Leda (detail) ghk | Portrait |

Callisto Piazza
(1500-1561) was an Italian painter. Callisto, a member of the Piazza family of painters, was born in Lodi, Lombardy. In 1523 he was working in Brescia. His first dated and signed work is from the following year, and shows a typical Brescian style. This style was then emerging, and included artists such as Romanino and Moretto. Piazza shows influences from contemporaries such as Dosso Dossi and Ludovico Mazzolino of the Ferrarese school, as well as Giovanni Agostino da Lodi. In 1526-1529 Piazza worked in Val Camonica, at Erbanno, Borno, Breno, Esine and Cividate Camuno. In 1529 he returned to his native Lodi where he formed a workshop with his brothers Cesare and Scipione (died 1552). In 1538, while in Crema, he married the noblewoman Francesca Confalonieri. Later Callisto moved to Milan, where he received numerous commissions, such as the decoration of the San Girolamo chapel in Santa Maria Presso San Celso (1542); the decoration of the refectory of the convent of Sant'Ambrogio (1545); the frescoes for the Saletta Negra in the Castello Sforzesco; and the decoration of the Simonetta chapel in San Maurizio al Monastero Maggiore (1555), largely executed with the assistance of his son Fulvio. He also worked in Lodi at the Incoronata (1454), Novara, at the Abbey of Chiaravalle and other areas of Lombardy.
Edouard Debat Ponsan
French Academic Painter, 1847-1913 1847-1913.French painter. He trained in Toulouse and later at the Ecole des Beaux-Arts in Paris under Alexandre Cabanel. In 1873 he won second place in the Prix de Rome and in 1874 the Prix Troyon of the Institut. From the Institut he received a bursary that enabled him to visit Italy. In 1870 he made his debut at the Salon under the name Ponsan-Debat and afterwards exhibited there such genre and history paintings as Jephthah's Daughter (1876; Carcassonne, Mus. B.-A.). He also executed religious works, some of which were for churches and cathedrals: he painted St Paul before the Areopagus (1877) for the church at Courbevoie and the Pity of St Louis for the Dead (1879) for the cathedral at La Rochelle. From 1880 Debat-Ponsan was the name under which he exhibited. The Massage (1883; Toulouse, Mus. Augustins) shows a white female nude massaged by a negress, and the subject attracted comment from contemporary critics. He also painted a number of landscapes, including Corner of the Vineyard (1888; Nantes, Mus. B.-A.). These were painted in a style similar to that of Jules Bastien-Lepage and, when they included figures, were often sentimental. His reputation depended, however, on his portraits, which are distinguished by their vigorous colour and precision, as seen in the portrait of Pouyer-Quertier (c. 1885; Rouen, Mus. B.-A.). Most notable was his portrait of General Boulanger (1887; untraced), which was shown at the Salon of 1887 and was accepted in 1889 for the Exposition Universelle in Paris. Amid scandal, Debat-Ponsan withdrew it soon after the opening because he thought that the Exposition was badly organized and his painting was not shown to advantage. He refused the bronze medal awarded it by the jury. In later years, while producing such paintings as Christ on the Mountain (1889; Toulouse, Mus. Augustins), he increasingly responded to contemporary events in his work.
