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 :. | Cartoon | Detail of Madonna of the Rocks | Portrait of Ginerva de'Benci-u | Madonna and Child with a Pomegranate | Adoration of the Magi |

Prout, Samuel
English Painter, 1783-1852 Painter, draughtsman and writer. Together with his fellow pupil Benjamin Robert Haydon, Prout was encouraged to study drawing by the headmaster of his grammar school in Plymouth. In 1801 he met the topographer and antiquarian John Britton, who, impressed with his work, invited him to London the following year to make drawings of antiquarian subjects and copy works of other artists, including Thomas Hearne, William Alexander and J. M. W. Turner.
Louis Jean Francois Lagrenee
(December 30, 1724 - June 19, 1805) was a French painter, a pupil of Carlo Vanloo. His younger brother Jean-Jacques Lagren??e was also a painter. Lagrenee was born in Paris. In 1755 he became a member of the Royal Academy, presenting as his diploma picture the Rape of Deianira (Louvre). He visited Saint Petersburg at the call of the empress Elizabeth, and on his return was named in 1781 director of the French Academy in Rome, a position he kept until 1787. He there painted the Indian Widow, one of his best-known works. In 1804 Napoleon conferred on him the cross of the l??gion d'honneur, and on June 19, 1805 he died in the Louvre, of which he was honorary keeper.
Willem van de Velde the Elder
(c. 1611 - 13 December 1693) was a Dutch Golden Age seascape painter. Willem van de Velde, known as the Elder, a marine draughtsman and painter, was born in Leiden, the son of a Flemish skipper, Willem Willemsz. van de Velde, and is commonly said to have been bred to the sea. In 1706 Bainbrigg Buckeridge noted that he eunderstood navigation very welle. He married Judith Adriaensdochter van Leeuwen in Leiden, the Netherlands, in 1631. His three known legitimate children were named Magdalena, born 1632; Willem, known as the Younger, also a marine painter, born 1633; and Adriaen, a landscape painter, born 1636. His marriage was stormy, at least in its later years. David Cordingly relates that Willem the Elder fathered two children out of wedlock in 1653, one eby his maidservant, and the other by her friend. Nine years later the Elder and his wife went through a legal separation, eon account of legal disputes and the most violent quarrelse. The immediate cause of the dispute was his affair with a married woman.e Michael S. Robinson noted that eon 17/27 July 1662, he and his wife agreed to part. A condition of the separation was that the Elder could recover from his son Adriaen etwo royal giftse, presumably gifts from Charles II for work done in England.e Cordinglyes account further relates that the dispute was still continuing after another ten years, since ein the autumn of 1672 Judith complained to the womanes husband.e Robinson adds that by 1674 the couple emust have been reconcilede, for at a chance meeting with Pieter Blaeu in Amsterdam in July the Elder explained that he was only visiting for a few days ein order to fetch his wifee. His son, Adriaen, had died in Amsterdam in 1672, and Willem the Elder was also fetching his grandson, similarly named Adriaen, who was then aged two. After his move to England, the exact date of which is uncertain, but reportedly at the end of 1672 or beginning of 1673, he is said to have lived with his family in East Lane, Greenwich, and to have used the Queenes House, now part of the National Maritime Museum in Greenwich, as a studio. Following the accession of William and Mary as King and Queen of England, it appears that this facility was no longer provided, and by 1691 he was living in Sackville Street, now close to Piccadilly Circus. He died in London, and was buried in St Jameses Church, at the south end of the street.
