LEONARDO da Vinci
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.

Ercole de' Roberti (c. 1451 ?C 1496), also known as Ercole Ferrarese or Ercole da Ferrara, was an Italian artist of the Early Renaissance and the School of Ferrara. He was profiled in Vasari's Le Vite delle pi?? eccellenti pittori, scultori, ed architettori.
The son of the doorkeeper at the Este castle, Ercole later held the position of court artist for the Este family in Ferrara. According to Vasari:
By 1473, when he was 17, Ercole had left Ferrara and was working in Bologna in the studio of Francesco del Cossa. (According to Vasari, Ercole also apprenticed under Lorenzo Costa in Bologna, but this seems unlikely as he was Lorenzo's senior by seveal years). He is known to have collaborated in the frescoes of Palazzo Schifanoia.
Ercole's first mature works are his contributions to the Griffoni Chapel for the San Petronio Basilica in Bologna: a predella depicting the Miracles of St Vincent Ferrer (c.1473) (now in the Pinacoteca of the Vatican), and lateral pilasters for the altarpiece commissioned from del Cossa.
In 1480, Ercole created a large altarpiece with a Madonna and Child Enthroned with Saints for Santa Maria in Porto in Ravenna, which is now in the Brera, Milan. Portraits of Giovanni II Bentivoglio and Ginevra Bentivoglio attributed to Ercole de' Roberti (c. 1480) are in the National Gallery of Art, Washington, D.C.
Ercole succeeded Cosm?? Tura as court painter to the Este family in Ferrara around 1486. His role apparently went far beyond making art: he accompanied Alfonso d'Este on a papal visit to Rome, served as wardrobe manager for Isabella d'Este's wedding in Mantua, and may even have made salamis.
A painting of Portia and Brutus (c. 1486-90), believed to be painted for Eleonora of Aragon, duchess of Ferrara, is in the Kimbell Art Museum, Fort Worth, Texas. Ercole's painting of Saint Jerome in the Wilderness from this period is in the collection of the J. Paul Getty Museum, Los Angeles.Alexandre Seon
French Symbolist Painter, 1855-1917
was a French Symbolist artist, illustrator and decorator. Seon studied at the Beaux-Arts of Lyon and Paris, becoming a student of Puvis de Chavannes in 1891, with whom he later collaborated. He was closely associated with Josephin Peladan and his Salon de la Rose-Croix, and designed the frontispiece for Peladan's 1891 novel l'Androgyne William Matthew Prior
