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 | The Annunciation | Bacchus | Study of a child | The Last Supper |

David van der Plas
David van der Plas (1647-1704), was a Dutch Golden Age portrait painter. David van der Plas became famous as a portrait painter, and his most illustrious patron was Cornelis Tromp. In 1684 he married Cornelia van der Gon of Haarlem, the daughter of the castellan (kastelein) of the Oude Doelen, the meeting quarters of the Haarlem schutterij (the building currently houses the Stadsbibliotheek Haarlem). David van der Plas' brother-in-law was the painter Govert van der Leeuw and his pupil was Jacob Appel. His wife Cornelia van der Gon was the rich heiress of the Amsterdam architect Adriaan Dortsman (ca. 1636-1682), who designed the round Lutheran church on the Singel. The marriage was childless, and Cornelia spent her time on her doll houses, which Dortsman had helped design and which Van der Plas helped decorate. The landscape painter Jan Wijnants also painted miniatures for these doll houses. Cornelia died in 1701, and after the death of Van der Plas, the doll houses were sold at auction to Sara Rothe, who used them to decorate her own doll houses.

George Dawe
1781-1829 British George Dawe Locations English painter and writer. He was the son of the mezzotint engraver Philip Dawe who taught him engraving. He continued to concentrate on engraving when he entered the Royal Academy Schools, London, in 1796, producing portraits until 1802, when he turned to history painting. In 1803 he won a gold medal and the following year made his d?but at the Royal Academy, where he exhibited until 1818, often showing such anecdotal and literary works as Imogen Found in the Cave of Belarius (exh. RA 1809; London, Tate). He was elected an ARA in 1809 and an RA in 1814 and soon afterwards returned to portrait painting. In 1816 he painted a number of portraits of George IV daughter Princess Charlotte (e.g. London, N.P.G.), several of which were engraved. In 1817 he went to Brussels and was present at the review of the allied troops by Arthur Wellesley, 1st Duke of Wellington in Cambrai. Soon afterwards he was invited by Tsar Alexander I of Russia to paint the portraits of all the senior officers who had taken part in the Napoleonic Wars. He travelled to St Petersburg in 1819 where, over the next nine years, he painted nearly 400 portraits. These were placed in a specially built gallery (destr.) in the Winter Palace in St Petersburg. He returned briefly to England in 1828 before travelling to Berlin, where he painted the portraits of Ernest Augustus, Duke of Cumberland (1828; London, N.P.G.) and Frederick William III, King of Prussia (1828; untraced). From Berlin he moved to St Petersburg and then to Warsaw before being forced by illness to return to England, where he died shortly afterwards. His book The Life of George Morland with Remarks on his Works (1807) is both a lively account of his godfather dissipated lifestyle and a fairly critical appreciation of his work.
