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 :. | Leda h | The adoration of the Konige | Cecila Gallerani (mk45) | Annunciation sgt66 | Profile of an old man |

Francis Quarles
1592-1644,was born at Romford, London Borough of Havering, and baptized there on May 8 1592. Francis traced his ancestry to a family settled in England before the Norman Conquest with a long history in royal service. His great-grandfather, George Quarles, was Auditor to Henry VIII, and his father, James Quarles, held several places under Elizabeth I and James I, for which he was rewarded with an estate called Stewards in Romford. His mother, Joan Dalton, was the daughter and heiress of Eldred Dalton of Mores Place, Hadham. There were eight children in the family; the eldest, Sir Robert Quarles, was knighted by James I in 1608. Francis was entered at Christ's College, Cambridge, in 1608, and subsequently at Lincoln's Inn. He was made cupbearer to the Princess Elizabeth, in 1613, remaining abroad for some years; and before 1629 he was appointed secretary to Ussher, the primate of Ireland. About 1633 he returned to England, and spent the next two years in the preparation of his Emblems. In 1639 he was made city chronologer, a post in which Ben Jonson and Thomas Middleton had preceded him. At the outbreak of the Civil War he took the Royalist side, drawing up three pamphlets in 1644 in support of the king's cause. It is said that his house was searched and his papers destroyed by the Parliamentarians in consequence of these publications. Quarles married in 1618 Ursula Woodgate, by whom he had eighteen children. His son, John Quarles (1624-1665), was exiled to Flanders for his Royalist sympathies and was the author of Fons Lachrymarum (1648) and other poems. The work by which Quarles is best known, the Emblems, was originally published in 1635, with grotesque illustrations engraved by William Marshall and others. The forty-five prints in the last three books are borrowed from the Pia Desideria (Antwerp, 1624) of Herman Hugo. Each "emblem" consists of a paraphrase from a passage of Scripture, expressed in ornate and metaphorical language, followed by passages from the Christian Fathers, and concluding with an epigram of four lines. The Emblems was immensely popular with the common people, but the critics of the 17th and 18th centuries had no mercy on Quarles. Sir John Suckling in his Sessions of the Poets disrespectfully alluded to him as he "that makes God speak so big in's poetry." Pope in the Dunciad spoke of the Emblems, "Where the pictures for the page atone And Quarles is saved by beauties not his own."
