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 :. | The Adoration of the Magi | St John the Baptist t | Annunciation (detail) fg47 | The Annunciation | La belle Ferronire dg |

Peter Paul Rubens
Flemish Baroque Era Painter, 1577-1640 Peter Paul Rubens (June 28, 1577 ?C May 30, 1640) was a prolific seventeenth-century Flemish Baroque painter, and a proponent of an exuberant Baroque style that emphasized movement, color, and sensuality. He is well-known for his Counter-Reformation altarpieces, portraits, landscapes, and history paintings of mythological and allegorical subjects. In addition to running a large studio in Antwerp which produced paintings popular with nobility and art collectors throughout Europe, Rubens was a classically-educated humanist scholar, art collector, and diplomat who was knighted by both Philip IV, king of Spain, and Charles I, king of England. Rubens was a prolific artist. His commissioned works were mostly religious subjects, "history" paintings, which included mythological subjects, and hunt scenes. He painted portraits, especially of friends, and self-portraits, and in later life painted several landscapes. Rubens designed tapestries and prints, as well as his own house. He also oversaw the ephemeral decorations of the Joyous Entry into Antwerp by the Cardinal-Infante Ferdinand in 1635. His drawings are mostly extremely forceful but not detailed; he also made great use of oil sketches as preparatory studies. He was one of the last major artists to make consistent use of wooden panels as a support medium, even for very large works, but he used canvas as well, especially when the work needed to be sent a long distance. For altarpieces he sometimes painted on slate to reduce reflection problems. His fondness of painting full-figured women gave rise to the terms 'Rubensian' or 'Rubenesque' for plus-sized women. The term 'Rubensiaans' is also commonly used in Dutch to denote such women.
Louis-Marin Bonnet
French, 1736 - 1793 French engraver and publisher. He came from a family of artisans and owed his training in engraving to his brother-in-law, the engraver Louis Legrand (1723-1808). Through Legrand, Bonnet became the pupil of Jean-Charles Francois in 1756, a year before the latter discovered the CRAYON MANNER technique of engraving, designed to reproduce the effect of a coloured-chalk drawing. Around the end of 1757 Bonnet used the new technique to engrave a Cupid after Francois Eisen. Gilles Demarteau, a rival of Jean-Charles Francois
Pier Leone Ghezzi
(Rome, 28 June 1674 - Rome, 6 March 1755) was an Italian Rococo painter and caricaturist active in Rome. Caricature of composer Antonio Vivaldi by Pier Leone GhezziGhezzi was born in Rome. His father, Giuseppe Ghezzi, (1634-1721), also trained Antonio Amorosi, and was a secretary to the Roman Accademia di San Luca. Pier Leone himself joined the Academy in 1705 and he executed a painting, the Allegory of Gratitude, to be donated to the institution, as was customary. He was the godson of Carlo Maratta. Pier Leone is known for his frescoes in the Villa Falconieri of Frascati. His pen and gouache caricatures are much freer in emotion than his state portraiture, and often depict named individuals or professions in satirical fashion.
