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 :. | Madonna with the Yarnwinder | Six studies fur naked or clothed men | La belle Ferronire dg | The Last Supper | Annunciation (detail) sg77 |

Julius Caesar Ibbetson
1759-1817 British In 1785, Ibbetson began exhibiting at the Royal Academy with View of North Fleet. Mitchell calls George Biggin (1783), which is one of Ibbetson's earliest known works, "an accomplished full-length portrait in the Gainsborough tradition, [which] should be considered as a milestone in the development of an artist who was entirely self-taught". Through the efforts of Captain William Baillie in 1787, Ibbetson was made draughtsman to Colonel Charles Cathcart on the first British embassy to Peking (Beijing); he made many watercolor drawings of the animals and plants on the journey. While he was away, his Ascent of George Biggin, esq. from St. George's Fields, June 29th 1785 was exhibited at the Royal Academy to great critical and popular acclaim. In 1789, Ibbetson went to visit the Viscount Mountstuart at Cardiff Castle in Wales. He spent decades drawing the scenery there and, according to Mitchell, "[h]is detailed watercolours of iron furnaces, coal staithes, and copper mines foreshadow the work of Joseph Wright of Derby and J. M. W. Turner and constitute an important record of the early industrial developments in that region, but are less well known than his more numerous scenes of folk life and picturesque scenery." After a visit to the Isle of Wight in 1790, he began painting shipwrecks and smugglers. David Murray, 2nd Earl of Mansfield, and his wife commissioned Ibbetson to decorate Kenwood House, in 1794. This distracted him from the death of his wife and caring for their three children. Her death had "provoked a minor nervous breakdown, exacerbated by near destitution", but the Kenwood project relieved that stress. Four years later, he moved to Liverpool to work for Thomas Vernon. In 1801 he married his second wife, Bella Thompson, and moved to Ambleside. Ibbetson acquired several generous patrons in Liverpool and in Edinburgh: William Roscoe, Sir Henry Nelthorpe, and the Countess of Balcarress. The last prompted him to write and publish his instruction manual An Accidence, or Gamut, of Painting in Oil (1803). In 1803, he met the Yorkshire philanthropist William Danby and in 1805 moved to Masham to be near him. The next 14 years of his life were the most settled of his life. Ibbetson died on 13 October 1817 and was buried in the churchyard of St Mary's, Masham. Benjamin West described Ibbetson as the "Berchem of England" in recognition of his debt to the Dutch 17th century landscape painters. According to Mitchell, "[h]is watercolours are prized for their delicacy and sureness of line". Many were engraved for projects such as John Church's A Cabinet of Quadrupeds and John Boydell's Shakespeare Gallery.
