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 :. | Aurelio Luini attributed, profile of an old man | The Annunciation | The Virgin and Child with St Anne | Study fur the head of a Madchens | Madonna Litta (detail sdg |

Alexander Pope
(21 May 1688 - 30 May 1744) was an eighteenth-century English poet, best known for his satirical verse and for his translation of Homer. He is the third most frequently quoted writer in The Oxford Dictionary of Quotations, after Shakespeare and Tennyson. Pope is famous for his use of the heroic couplet. Pope was born to Edith Pope (1643-1733) and Alexander Pope Senior. (1646-1717) a linen merchant of Plough Court, Lombard Street, London, who were both Catholics. Pope's education was affected by the penal law in force at the time upholding the status of the established Church of England, which banned Catholics from teaching, attending a university, voting, or holding public office on pain of perpetual imprisonment. Pope was taught to read by his aunt, then went to Twyford School in about 1698-9. He then went to two Catholic schools in London. Such schools, while illegal, were tolerated in some areas. In 1700, his family moved to a small estate at Popeswood in Binfield, Berkshire, close to the royal Windsor Forest. This was due to strong anti-Catholic sentiment and a statute preventing Catholics from living within 10 miles (16 km) of either London or Westminster. Pope would later describe the countryside around the house in his poem Windsor Forest. Pope's formal education ended at this time, and from then on he mostly educated himself by reading the works of classical writers such as the satirists Horace and Juvenal, the epic poets Homer and Virgil, as well as English authors such as Geoffrey Chaucer, William Shakespeare and John Dryden. He also studied many languages and read works by English, French, Italian, Latin, and Greek poets. After five years of study, Pope came into contact with figures from the London literary society such as William Wycherley, William Congreve, Samuel Garth, William Trumbull, and William Walsh. At Binfield, he also began to make many important friends. One of them, John Caryll (the future dedicatee of The Rape of the Lock), was twenty years older than the poet and had made many acquaintances in the London literary world. He introduced the young Pope to the aging playwright William Wycherley and to William Walsh, a minor poet, who helped Pope revise his first major work, The Pastorals. He also met the Blount sisters, Teresa and (his alleged future lover) Martha, both of whom would remain lifelong friends. From the age of 12, he suffered numerous health problems, such as Pott's disease (a form of tuberculosis that affects the bone) which deformed his body and stunted his growth, leaving him with a severe hunchback. His tuberculosis infection caused other health problems including respiratory difficulties, high fevers, inflamed eyes, and abdominal pain. He never grew beyond 1.37 m (4 ft 6 in) tall. Pope was already removed from society because he was Catholic; his poor health only alienated him further. Although he never married, he had many female friends to whom he wrote witty letters. He did have one alleged lover,
