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 :. | Madonna and Child with a Pomegranate | Christ's Head | Portrait of a Musician | The Madonna of the Carnation | Bacchus |

Leopold Robert
(13 May 1794 - 20 March 1835), Swiss painter, was born at La Chaux-de-Fonds (Neuchâtel) in Switzerland, but left his native place with the engraver Girardet at the age of sixteen for Paris. He was on the eve of obtaining the grand prix for engraving when the events of 1815 blasted his hopes, for Neuchâtel was restored to Prussia, and Robert was struck off the list of competitors as a foreigner. Whilst continuing his studies under Girardet he had never ceased to frequent the studio of David, and he now determined to become a painter, and only returned to his native country when his master himself was exiled. At Neuchâtel he attracted the notice of Roullet de Mezerac, who enabled him by a timely loan to proceed to Rome. In depicting the customs and life of the people, of southern Italy especially, he showed peculiar feeling for the historical characteristics of their race. After executing many detached studies of Italian life Robert conceived the idea of painting four great works which should represent at one and the same time the four seasons in Italy and the four leading races of its people. In the "Return from the Fete of the Madonna dell'Arco" (Louvre) he depicted the Neapolitans and the spring. This picture, exhibited at the Salon of 1827, achieved undoubted success and was bought for the Luxembourg by Charles X; but the work which appeared in 1831 the "Summer Reapers arriving in the Pontine Marshes" (Louvre), which became the property of Louis Philippe established the artist's reputation. Florence and her autumn vineyards should now have furnished him with his third subject. He attempted to begin it, but, unable to conquer his passion for Princess Charlotte Napoleon (then mourning the violent death of her husband, Robert's devoted friend), he threw up his work and went to Venice, where he began and carried through the fourth of the series, the "Fishers of the Adriatic." This work was not equal to the "Reapers." Worn by the vicissitudes of painful feeling, and bitterly discouraged, Robert committed suicide before his easel on 20 March 1835, on the tenth anniversary of the melancholy suicide of a brother to whom he had been much attached.

Marten van Cleve
Flemish, 1527-1581,Brother of Hendrik van Cleve III. His presumed date of birth is derived from a document of 2 April 1567 in which he declared his age to be 40. In 1551-2 he became a master in the Antwerp Guild of St Luke and, according to van Mander, followed his brother into the studio of Frans Floris. If this is correct, it was probably c. 1553-5, for motifs drawn from Floris's work appear in Marten van Cleve's paintings executed during these years. Marten married Maria de Greve on 7 January 1556, apparently setting up his own studio at about the same time. Apprentices are regularly recorded from 1558 onwards, and it is probable that his own sons, Gillis II, Marten the younger, Joris and Nicolaas, also worked in the studio. Throughout the 1560s and 1570s Marten van Cleve's workshop was very productive, but the majority of works painted consisted of copies of his own originals. Van Mander's statement that the artist collaborated with a number of landscape painters, including his brother Hendrik III, Gillis van Coninxloo III, Gillis Mostaert and Jacob Grimmer, is confirmed by 17th-century inventories.
