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 :. | Female head (La Scapigliata) wt | Profile of a man | The Virgin and Child with St Anne ey | Study fur the head of a Madchens | Study fur the adoration of the Konige |

GUARDI, Francesco
Italian Rococo Era Painter, 1712-ca.1793 The records of his parish in Venice show that Francesco Guardi was baptized on Oct. 5, 1712. His father, Domenico, who died when Francesco was 4, had a workshop. Francesco and his elder brother, Gian Antonio, worked in a small studio, carrying out such orders as they could get for almost anything the client wanted:mythological pictures, genre, flower pieces, battle scenes, altarpieces, and even, on rare occasions, frescoes. They did not hesitate to copy compositions by other artists, but what they borrowed they always transformed into something more capricious, less stable, more fragmentary in the refraction of light. Francesco did not emerge as an independent personality until 1760, when his brother died. Then, 48 years old, he married, established his own studio, and devoted himself chiefly to painting views of Venice. For the most part he worked in obscurity, ignored by his contemporaries. He was not even admitted to the Venetian Academy until he was 72 years old. Guardi and Canaletto have always been compared to one another because the buildings they chose to paint were often the same. But the way each artist painted them is very different. Canaletto's world is constructed out of line. It provides solid, carefully drawn, three-dimensional objects that exist within logically constructed three-dimensional space. Guardi's world is constructed out of color and light. The objects in it become weightless in the light's shimmer and dissolve in a welter of brushstrokes; the space, like the forms in space, is suggested rather than described. Canaletto belonged essentially to the Renaissance tradition that began with Giotto and, as it grew progressively tighter and more controlled, pointed the way to neoclassicism. Guardi belonged to the new baroque tradition that grew out of the late style of Titian and, as it became progressively looser and freer, pointed the way toward impressionism. Such differences appear even in Guardi's early view paintings, where he was obviously trying to copy Canaletto, such as the Basin of San Marco. The famous buildings are there, but they are far in the background, insubstantial, seeming to float. In front is a fleet of fishing boats, their curving spars seeming to dance across the surface of the canvas. What is important for Guardi is not perspective but the changing clouds and the way the light falls on the lagoon. Guardi became increasingly fascinated by the water that surrounds Venice. In late works, such as the famous Lagoon with Gondola, buildings and people have been stripped away until there is nothing but the suggestion of a thin line of distant wharfs, a few strokes to indicate one man on a gondola, a long unbroken stretch of still water, and a cloudless sky. Guardi also painted the festivals that so delighted visitors to the city, such as the Marriage of Venice to the Sea. This was a symbolic ceremony in which the doge, in the great gilded galley of the head of state, surrounded by a thousand gondolas, appeared before all Venice, in Goethe's image, "raised up like the Host in a monstrance." Of all Guardi's paintings the most evocative are his caprices, the landscapes born out of his imagination though suggested by the ruined buildings on the lonely islands of the Venetian lagoon. A gentle melancholy clings to such scenes.
