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.

His surname was originally van Aeken; Bosch refers to 's Hertogenbosch, where he was born and worked. Little is known of his life and training, although it is clear that he belonged to a family of painters. His paintings, executed in brilliant colors and with an uncanny mastery of detail, are filled with strangely animated objects, bizarre plants and animals, and monstrous, amusing, or diabolical figures believed to have been suggested by folk legends, allegorical poems, moralizing religious literature, and aspects of late Gothic art. Such works as the Garden of Earthly Delights (Prado) appear to be intricate allegories; their symbolism, however, is obscure and has consistently defied unified interpretation. Bosch clearly had an interest in the grotesque, the diabolical, the exuberant, and the macabre. He also may have been the first European painter to depict scenes of everyday life, although often with a strong element of the bizarre. King Philip II of Spain collected some of his finest creations. The Temptation of St. Anthony (Lisbon) and The Last Judgment were recurring themes. Other examples of his art may be seen in the Escorial and in Brussels. Examples of the Adoration of the Magi are in the Metropolitan Museum and in the Philadelphia Museum, which also has the Mocking of Christ. Bosch, who deeply influenced the work of Peter Bruegel the Elder, was hailed in the 20th cent. as a forerunner of the surrealists, and his work continues to influence many contemporary artists. BRAKENBURG, RichardDutch painter (b. 1650, Haarlem, d. 1702, Haarlem) Ozias HumphryOzias Humphry (or Humphrey) (8 September 1742 -9 March 1810) was a leading English painter of portrait miniatures, later oils and pastels, of the 18th century. He was elected to the Royal Academy in 1791, and in 1792 he was appointed Portrait Painter in Crayons to the King.
Born and schooled in Honiton, Devon, Humphrey was attracted by the gallery of casts opened by the Duke of Richmond and came to London to study art at Shipley's school. He also studied art in Bath (under Samuel Collins, taking over his practice in 1762); in Bath, he lodged with Thomas Linley. As a young artist, his talent was encouraged by Thomas Gainsborough and Sir Joshua Reynolds, among others. His problems with his sight, which ultimately led to blindness, began in the early 1770s and forced him to paint larger works in oils and pastel.
He travelled to Italy in 1773 with his great friend George Romney, stopping en route at Knole, near Sevenoaks in Kent, where the Duke of Dorset commissioned several works from him. His stay in Italy lasted until 1777.
On his return, his numerous subjects included George Stubbs (1777), fellow academician Dominic Serres, the chemist Joseph Priestley, and a portrait claimed to be of the teenage Jane Austen, from perhaps as early as 1790 (clothing styles suggest a later date), known as the "Rice" portrait after a later owner, though this has always been a controversial attribution of the sitter. This failed to reach its minimum estimate in a Christies auction in April 2007, and was withdrawn from sale. His pupils included John Opie. He compiled a fifty-page manuscript A Memoir of George Stubbs, based on what Stubbs had related to him; it is the only contemporary biography. This was edited and privately published in the 1870s and republished in 2005. He also knew William Blake and commissioned copies of some of his illustrated books. At least one of Blake's letters to him is a significant document for Blake's biographers.
