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 :. | Studies of children | Power and ortraits | The muscles of Thorax and shoulders in a lebnden person | Head of a girl | Leda (detail) ghk |

Pieter de Grebber
1600-1653 Dutch Pieter de Grebber Gallery Grebber was the son of Frans Pietersz de Grebber (1573?C1643), a painter and embroiderer in Haarlem, and would have been taught painting by his father and by Hendrick Goltzius. He was descended from a Catholic and artistic family (2 of his brothers, and his sister Maria, the mother-in-law of Gabriel Metsu, were known as painters). He was friendly with the priest and musicologist Jan Albertszoon Ban, and had a poem set to music by the Haarlem composer Cornelis Padbru??. In 1618, father and son went to Antwerp and negotiated with Peter Paul Rubens over the sale of his painting "Daniel in the lions pit". It was then handed - via the English ambassador in the Republic, Sir Dudley Carleton - to king Charles I. Pieter got important commissions not only in Haarlem, but also from the stadholder Frederik Hendrik. As such, he worked with on the decoration of the Huis Honselaarsdijk in Naaldwijk and at the Paleis Noordeinde in Huis ten Bosch in the Hague. He painted altar pieces for churches in Flanders and hidden Catholic churches in the Republic. He may also have worked for Danish clients.
Angelo Morbelli
Alessandria 1853-1918 Milan,Italian painter. He received his first lessons in drawing in Alessandria, and in 1867 he travelled on a local study grant to Milan, where he was based for the rest of his life. He enrolled at the Accademia di Brera and from 1867 to 1876 studied drawing and painting there under Raffaele Casnedi and Giuseppe Bertini, whose influence is seen in both the subject-matter and technique of his early works. These include perspectival views, anecdotal genre scenes and history paintings. In the Dying Goethe (1880; Alessandria, Pin. Civ.) the theatrical setting, enriched by a sophisticated execution and a well-modulated use of colour, derives from the teaching of Casnedi and Bertini, while the historic-romantic quality of this painting also recalls the style of Francesco Hayez.
paolo uccello
(b Florence, c. 1397; d Florence, 10 Dec 1475). Italian painter, draughtsman, mosaicist and designer of stained glass. His work vividly illustrates the principal issues of Florentine art during the first half of the 15th century. Trained within the tradition of the Late Gothic style, he eventually became a leading exponent of the application of linear perspective based on the mathematical system established by Filippo Brunelleschi and Leon Battista Alberti. It is the merging of these two diametrically opposed tendencies that forms the basis of Uccello's style. As well as painting on panel and in fresco (many of his works in this medium have been severely damaged), he was also a master mosaicist and produced designs for stained glass.
