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 :. | Lady with Emine | The Madonna of the Carnation | Portrait of Ginerva de'Benci | Cartoon | Portrait of Cecilia Gallarani |

Pierre-Jacques Cazes
(1676-1754) was a French historical painter, known as the teacher of, among others, Chardin. In 1703, he became part of the Academie, was named as director in 1743 and chancellor in 1746. He also worked in the Galerie d'Apollon in the Louvre in 1727 and produced a large number of religious paintings for churches in Paris and Versailles. His historical painting is in the same academic tradition as the French painters Charles Le Brun and Charles de Lafosse. He also painted paintings with mythological motifs and genre scenes. A portrait the artist wearing a wig and holding a portfolio was presented to the Academie Royale in 1734 by Chardin's friend Joseph Aved.
Parrocel, Joseph
French, 1646-1704 He studied with his father Barthelemy Parrocel (1595-1660) and then with his elder brother Louis Parrocel (1634-94). He went to Paris for four years to perfect his work and then, c. 1667, to Rome, where he became the pupil of the battle painter Jacques Courtois and was influenced by Salvator Rosa. He remained in Italy for eight years and stayed for a time in Venice, before returning to settle in Paris in 1675. He was approved (agree) by the Academie Royale de Peinture et de Sculpture in February 1676 and received as a full member in November of the same year, presenting the Siege of Maastricht (Draguignan, Mus. Mun.). His painted oeuvre consists principally of military scenes, particularly battles, and he received numerous royal commissions. In the period 1685-8 he executed 11 paintings for the Salle du Grand Couvert at the cheteau of Versailles (nine in situ; one in Tours, Mus. B.-A.; one in Dijon, Mus. B.-A.); in 1699 he painted the Crossing of the Rhine (Paris, Louvre.) for the cheteau of Marly, Yvelines, and in 1700 he executed the Fair at Bezons (Tours, Mus. B.-A.), anticipating the fetes galantes of Antoine Watteau. He was also the author of a number of hunting scenes . His most important religious paintings were the May of Notre-Dame de Paris of 1694, St John the Baptist Preaching (Arras, Mus. B.-A.) and St Augustin Succouring the Sick (c. 1703; Nantes, Mus. B.-A.), which was intended for the monastery in the Place des Victoires in Paris. He also contributed battle scenes to the backgrounds of portraits by Hyacinthe Rigaud and by Gabriel Blanchard. His technique was highly original in the context of his time; he employed a very free style of execution and used thick impasto and intense colours. He was also a prolific engraver, producing around 100 plates,
