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 :. | Madonna with the Yarnwinder (detail) dft | Six studies fur naked or clothed men | The last dinner | The Adoration of the Magi | Our Lady and St Anne |

John Ruskin,HRWS
1819-1900 English academic and critic, who had an enormous influence not only on architectural style but on the ways in which standards of aesthetics were judged. He used an Evangelical and polemical tone in his writings that not only reached a mass audience but received the approval of the Ecclesiologists. Initially encouraged by J. C. Loudon, he contributed to some of Loudon's publications, but his key works date from the late 1840s and 1850s. The Gothic Revival was well established when Ruskin published The Seven Lamps of Architecture (1849), which was an immediate success, encapsulating the mood of the period rather than creating new ideas. He argued that architecture should be true, with no hidden structure, no veneers or finishes, and no carvings made by machines, and that Beauty in architecture was only possible if inspired by nature. As exemplars worthy of imitation (he argued that the styles known to Man were quite sufficient, and that no new style was necessary) he selected Pisan Romanesque, early Gothic of Western Italy, Venetian Gothic, and English early Second Pointed as his paradigms. In the choice of the last, the style of the late C13 and early C14, he was echoing A. W. N. Pugin's preferences as well as that of most ecclesiologically minded Gothic Revivalists such as G. G. Scott. The Stones of Venice (1851C3) helped to promote that phase of the Gothic Revival in which Continental (especially Venetian) Gothic predominated. Deane and Woodward's University Museum, Oxford (1854C60), is an example of Venetian or Ruskinian Gothic. In particular, structural polychromy, featuring colour in the material used, rather than applied, was popularized by Ruskin's writings.
Filippo Napoletano
(c. 1587 - November 1629) was an Italian artist, with a peculiar output, mainly landscape and genre scenes and also drawings or etchings of diverse, often particular, items such as exotic soldiers, skeletons of animals, or cityscapes. He began his career in his native city, Naples (1600-1613) and moved to Rome in 1614-1617), where he appears to have encountered and felt influenced by the successful Flemish landscape painters such as Paul Bril, Goffredo Wals, and Adam Elsheimer. In 1617 Cosimo II dee Medici summoned him to Florence, where he worked closely with Jacques Callot. From notebooks, Filippo is known to have made hundreds of sketches of Tuscan landscapes and towns. Starting in 1620 he reproduced in etchings part of his collection of animal skeletons owned by Johann Faber, a Bavarian physician-naturalist residing in Rome and a member of the scientific Accademia dei Lincei. In 1622, Napoletano published twelve etchings of caprices (capprici) and military uniforms (which he signed as signed Teodor Filippo de Liagno). He is described by Giovanni Baglione as possessing a collection, a Wunderkammer of bellissime bizzarrie ("beautiful bizarre objects"), including among the objects exotic weaponry; fossilized plants; tiger, lion, and turtle skulls; oriental porcelain and sculpted crockery; a vest made of human skin; a harness for dragging whales on ice; a three-legged flea, Persian uniforms, and antiquities such as Roman coins, bronze lamps, and a few statuettes. After Napoletano death at Rome in 1628, bidding for such material was made by collectors such as Cardinal Ippolito Aldobrandini (future Clement VIII) and Cassiano dal Pozzo.
