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 :. | Portrait of Mona Lisa,La Gioconda (mk05) | Virgin and Child with St Anne and St John the Baptist | Cartoon | Adoration of the Magi | La Belle Ferronniere |

Samuel Butler
British author , (1835 - 1902) Samuel Butler was born on Dec. 4, 1835, in Langar, near Bingham, Nottinghamshire, the son of the local vicar. In a time of common paternal absolutism, his childhood seems to have been bleak and graceless. After taking a degree at Cambridge, he came into open conflict with his father over the question of his future profession, and at last he emigrated to New Zealand to become a sheep farmer. But though free of his father, he was not free of revolt, and the spirit of resentful rebelliousness marked much of his later life. In New Zealand he read Charles Darwin's Origin of Species and wrote a series of newspaper articles setting forth Darwin's ideas and ingeniously applying the evolutionary hypothesis to machines. Having made a modest fortune, he returned to England in 1864. Erewhon (1872), Butler's first book, is a mixture of satire, utopian theories, and serious speculation masked as whimsy. Set in the frame of a trip to an unknown land (Erewhon is an anagram of "no-where"), it has no real plot but is rather a description and discussion of the customs and institutions of Erewhon. In this land moral failings are treated as mental illness and cured by a "straightener," but physical illness and misfortune are considered crimes and severely punished. Children sign certificates absolving their parents of responsibility for their birth, and education is carried on in the College of Unreason. Butler's reflections on orthodox religion, begun in New Zealand, issued in The Fair Haven (1873), an ironic attempt to reconcile the New Testament with rationalistic criticism. In Life and Habit he returned to the question of evolution. In Evolution Old and New (1879), Unconscious Memory (1880), and Luck, or Cunning? (1887), he developed his ideas with an increasingly self-righteous resentment of what he conceived to be the Darwinians' deliberate concealment of the truth. Butler hoped to be able to restore will, intelligence, and design to a universe apparently made meaningless by the blind process of natural selection. The novel The Way of All Flesh, Butler's most famous work, was written between 1872 and 1885. It is the supposed biography of Ernest Pontifex, narrated by an older friend with an unrelenting candor deliberately affronting conventional pieties.

Giambattista Tiepolo
1696-1770 Italian painter, master of Venetian school. Tiepolo was famous in his own lifetime as a superb painter in fresco and a brilliant draftsman. A highly inventive artist, he could create spectacular effects in difficult sites, from the narrow gallery at the patriarchal palace at Udine in the mid-1720s to the vast staircase ceiling in the Residenz at Werzburg in the early 1750s. Contemporaries recognized his spirited, dynamic approach to subject matter and his frankly sensuous manner of painting. Tiepolo is comparable in his restless energy and imaginative power to Peter Paul Rubens, and essentially he worked with a similar baroque language of myth, allegory, and history, which he infused with a sense of freshness and modernity. His approach to religious art is characterized by candor and naturalism, while he was responsive to the different concerns of patrons and viewers at a time when the church was faced with new kinds of devotion and criticism. With the advent of neoclassicism, Tiepolo's art fell from favor: In an age that prized archaeological correctness, rationality, and ideals of improvement, his witty, Veronese-inspired conception of historical or classical subjects seemed frivolous, while his visually seductive qualities were seen as inimical to the serious intellectual aims of the new art. Nevertheless, his drawings and oil sketches continued to appeal to collectors, including Antonio Canova. The son of a Venetian shipping merchant, Tiepolo was apprenticed in 1710 to Gregorio Lazzarini (1655C1730), an artist of international reputation patronized by prominent Venetian families. Before becoming an independent master, he worked in the household of Doge Giovanni Corner; members of the Corner family were to be his most steadfast and liberal patrons. Lazzarini encouraged his pupils to study Venetian sixteenth-century art, and Tiepolo made drawings of some famous works for publication in Domenico Lovisa's Gran Teatro di Venezia of 1717. His early involvement with the thriving Venetian engraving and publishing world was renewed in 1724 when he made drawings of antique sculpture as illustrations for Scipione Maffei's Verona Illustrata, an experience that gave Tiepolo an imaginative empathy with fragmentary antique remains, which recur in his drawings, etchings, and paintings. As well as studying the art of the past, Tiepolo looked to the tenebrism of Federico Bencovich (1677C1753) and the realism and monumentality of Giovanni Battista Piazzetta (1682C1754). In 1719 Tiepolo married Cecilia Guardi, with whom he was to have nine children. By then, the artist was working for a network of mercantile and noble patrons on religious and secular subjects.
