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 an old man | Leda | Muscles and bone of leg and Hufte | The Refectory with the Last Supper after restoration g |

Lucas van Leyden
1489-1533 Dutch Lucas van Leyden Galleries Lucas van Leyden (Leiden, 1494 ?C August 8, 1533 in Leiden), also named either Lucas Hugensz or Lucas Jacobsz, was a Dutch engraver and painter, born and mainly active in Leiden, who was among the first Dutch exponents of genre painting and is generally regarded as one of the finest engravers in the history of art. He was the pupil of his father, from whose hand no works are known, and of Cornelis Engelbrechtsz, but both of these were painters whereas Lucas himself was principally an engraver. Where he learnt engraving is unknown, but he was highly skilled in that art at a very early age: the earliest known print by him (Mohammed and the Murdered Monk) dates from 1508, when he was perhaps only 14, yet reveals no trace of immaturity in inspiration or technique. Lot and his daughters (ca. 1509)In 1514 he entered the Painters' Guild at Leiden. He seems to have travelled a certain amount, and visits are recorded to Antwerp in 1521, the year of D??rer's Netherlandish journey, and to Middelburg in 1527, when he met Jan Mabuse. An unbroken series of dated engravings makes it possible to follow his career as a print-maker and to date many of his paintings, but no clear pattern of stylistic development emerges. D??rer was the single greatest influence on him, but Lucas was less intellectual in his approach, tending to concentrate on the anecdotal features of the subject and to take delight in caricatures and genre motifs. Carel van Mander characterizes Lucas as a pleasure-loving dilettante, who sometimes worked in bed, but he left a large oeuvre, in spite of his fairly early death, and must have been a prodigious worker. Lucas had a great reputation in his day (Vasari even rated him above D??rer) and is universally regarded as one of the greatest figures in the history of graphic art (he made etchings and woodcuts as well as engravings and was a prolific draughtsman). His status as a painter is less elevated, but he was undoubtedly one of the outstanding Netherlandish painters of his period. He was a pioneer of the Netherlandish genre tradition, as witness his Chess Players (Gemäldegalerie, Berlin) which actually represents a variant game called 'courier' - and his Card Players (National Gallery of Art, Washington), while his celebrated Last Judgement triptych (Lakenhal Museum, Leiden, 1526-27) shows the heights to which he could rise as a religious painter. It eloquently displays his vivid imaginative powers, his marvellous skill as a colourist and his deft and fluid brushwork.
