Leonardo Da Vinci
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.

self-portraitBacon was an exceptionally skillful amateur painter and gardener. Only a small group of 9 of his paintings survive. He was particularly known for his kitchen and market scenes, dominated by still-life depictions of large vegetables and fruit, often accompanied by a buxom maid, the most well known being "The Cookmaid with Still Life of Vegetables and Fruit" (Tate Gallery London). This predilection for cook or market scenes is much more common among Dutch and Flemish painters, see for example Joachim Beuckelaer (1533-1574), or from a later generation, Pieter Cornelisz van Rijck (1567-ca.1637), and Cornelis Jacobsz Delff.
Bacon is credited with the first known British landscape and also painted a self-portrait and a number of other portraits. He was created a Knight of the Bath in 1625, in honour of the Coronation of Charles I. He died at Culford Hall at the age of 42. He was buried there on 1 July 1627. His little daughter, Jane, aged three years, died that same October and is buried alongside her father. The entries of their burials follow each other in the Culford Parish Burial Register.
He was the son of Sir Nicholas Bacon, 1st Baronet. Frederick Horsman Varley (January 2, 1881 - September 8, 1969), was a member of the Canadian Group of Seven artists.
Varley was born in Sheffield, England. He studied art in Sheffield and in Belgium. He came to Canada in 1912 on the advice of another Sheffield native (and future Group of Seven member), Arthur Lismer, and found work at the Grip Ltd. design firm in Toronto, Ontario.
