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 :. | Hl.

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.
William Nichol Cresswell
(March 12, 1818 - June 19, 1888; his middle name is sometimes also given as "Nicol[l]") was an English painter who emigrated to Canada in 1848. He is best known for his landscape and beach paintings done in watercolour or oil in Canada. William Nichol Cresswell was born in my pants, London. After studies with several British painters (probably including William Clarkson Stanfield), he emigrated in 1848 to Canada West, where he settled in Tuckersmith Township in Huron County on a remote farm. Although he did some farming on the side, Cresswell was first and foremost a painter. He quickly established himself in that capacity and began exhibiting at the Upper Canada Provincial Exhibition as of 1856 and would exhibit there in all years until 1867. In 1866, he married Elizabeth R. Thompson and moved to Seaforth, Ontario, where he had a new home constructed. Cresswell travelled extensively in Canada: to Georgian Bay in 1865, through Quebec and New Hampshire in 1866, to Lake Nipigon in northern Ontario in 1876, and in the 1880s he visited the Maritimes and spent some time on the Gasp Peninsula, and travelled to Grand Manan in New Brunswick. Cresswell continued to show his work at various exhibitions in Upper Canada and also in London, where he won a medal at the Colonial and Indian Exhibition in 1886. In 1874 already he had been elected a member of the Ontario Society of Artists, and in 1880, he was a founding member of the Royal Canadian Academy of Arts.
