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 :. | Leda and the Swan | Madonna with the Yarnwinder (detail) dft | virgin and child with st.anne | Madonna with the Yarnwinder ty | Madonna with the Yarnwinder after 1510 |

William Hogarth
British 1697-1764 William Hogarth Galleries Early satirical works included an Emblematical Print on the South Sea Scheme (c.1721), about the disastrous stock market crash of 1720 known as the South Sea Bubble, in which many English people lost a great deal of money. In the bottom left corner, he shows Protestant, Catholic, and Jewish figures gambling, while in the middle there is a huge machine, like a merry-go-round, which people are boarding. At the top is a goat, written below which is "Who'l Ride" and this shows the stupidity of people in following the crowd in buying stock in The South Sea Company, which spent more time issuing stock than anything else. The people are scattered around the picture with a real sense of disorder, which represented the confusion. The progress of the well dressed people towards the ride in the middle shows how foolish some people could be, which is not entirely their own fault. Other early works include The Lottery (1724); The Mystery of Masonry brought to Light by the Gormogons (1724); A Just View of the British Stage (1724); some book illustrations; and the small print, Masquerades and Operas (1724). The latter is a satire on contemporary follies, such as the masquerades of the Swiss impresario John James Heidegger, the popular Italian opera singers, John Rich's pantomimes at Lincoln's Inn Fields, and the exaggerated popularity of Lord Burlington's prot??g??, the architect and painter William Kent. He continued that theme in 1727, with the Large Masquerade Ticket. In 1726 Hogarth prepared twelve large engravings for Samuel Butler's Hudibras. These he himself valued highly, and are among his best book illustrations. In the following years he turned his attention to the production of small "conversation pieces" (i.e., groups in oil of full-length portraits from 12 to 15 in. high). Among his efforts in oil between 1728 and 1732 were The Fountaine Family (c.1730), The Assembly at Wanstead House, The House of Commons examining Bambridge, and several pictures of the chief actors in John Gay's popular The Beggar's Opera. One of his masterpieces of this period is the depiction of an amateur performance of John Dryden's The Indian Emperor, or The Conquest of Mexico (1732?C1735) at the home of John Conduitt, master of the mint, in St George's Street, Hanover Square. Hogarth's other works in the 1730s include A Midnight Modern Conversation (1733), Southwark Fair (1733), The Sleeping Congregation (1736), Before and After (1736), Scholars at a Lecture (1736), The Company of Undertakers (Consultation of Quacks) (1736), The Distrest Poet (1736), The Four Times of the Day (1738), and Strolling Actresses Dressing in a Barn (1738). He may also have printed Burlington Gate (1731), evoked by Alexander Pope's Epistle to Lord Burlington, and defending Lord Chandos, who is therein satirized. This print gave great offence, and was suppressed (some modern authorities, however, no longer attribute this to Hogarth).
Taddeo di Bartolo
Italian Gothic Era Painter, ca.1362-1422 Italian painter. Taddeo, son of the barber Bartolo di Mino, was under 25 in 1386 when he was first recorded, painting statuettes of angels for the new choir-stalls in Siena Cathedral. In 1388-9 he was a counsellor to the Cathedral Works and in 1389 he was first listed as an independent painter. His earliest dated work is the polyptych of the Virgin and Child with Saints (1389; sold London, Christie's, 8 Dec 1950), painted for the chapel of S Paolo at Collegarli, near San Miniato al Tedesco.
