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 :. | anna sjalv tredje | The muscles of Thorax and shoulders in a lebnden person | Virgin of the Rocks | Mona Lisa (La Gioconda) sdg | Adoration of the Magi (mk08) |

Osbert, Alphonse
French Symbolist Painter, 1857-1939 French painter. He studied at the Ecole des Beaux-Arts and in the studios of Henri Lehmann, Fernand Cormon and L?on Bonnat. His Salon entry in 1880, Portrait of M. O. (untraced), reflected his early attraction to the realist tradition of Spanish 17th-century painting. The impact of Impressionism encouraged him to lighten his palette and paint landscapes en plein air, such as In the Fields of Eragny (1888; Paris, Y. Osbert priv. col.). By the end of the 1880s he had cultivated the friendship of several Symbolist poets and the painter Puvis de Chavannes, which caused him to forsake his naturalistic approach and to adopt the aesthetic idealism of poetic painting. Abandoning subjects drawn from daily life, Osbert aimed to convey inner visions and developed a set of pictorial symbols. Inspired by Puvis, he simplified landscape forms, which served as backgrounds for static, isolated figures dissolved in mysterious light. A pointillist technique, borrowed from Seurat, a friend from Lehmann's studio, dematerialized forms and added luminosity. However, Osbert eschewed the Divisionists' full range of hues in his choice of blues, violets, yellows and silvery green. Osbert's mysticism is seen in his large painting Vision
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.
