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 :. | Unfinished painting of St. Jerome in the Wilderness | St John in the Wilderness | The organs of the woman | Mona Lisa (mk45) | Anatomical study of the brain and the scalp |

Arthur hacker,R.A.
1858-1919 was an English classicist painter. Born in London in 1858, Hacker was the son of Edward Hacker, a line engraver specialising in animal and sporting prints (who was also for many years the official Registrar of Births, Marriages and Deaths for Kentish Town in the St Pancras registration district, north London). In his art he was most known for painting religious scenes and portraits, and his art was also influenced by his extensive travels in Spain and North Africa. He studied at the Royal Academy between 1867 and 1880, and at the Atelier Bonnat in Paris. He was twice exhibited at the Royal Academy, in 1878 and 1910, and was elected an Academician in 1910. In 1894 he was the subject of a bust by Edward Onslow Ford. An original portrait by Hacker of Sir Alfred Keogh by hangs in the RAMC HQ Mess at Millbank, London. He died in London on November 12, 1919. In 1902,
Hieronimo Custodis
(also spelled Hieronymus, Heironimos) (died c. 1593) was a Flemish portrait painter active in England in the reign of Elizabeth I. A native of Antwerp, Custodis was one of many Flemish artists of the Tudor court who had fled to England to avoid the persecution of Protestants in the Spanish Netherlands.He is thought to have arrived in England sometime after the fall of Antwerp to the forces of the Duke of Parma in 1585. Three English portraits by Custodis signed and dated 1589 firmly establish him as resident in London by that year. Sir Roy Strong attributes a portrait of Sir Henry Bromley dated 1587 to Custodis, suggesting an earlier arrival, and has verified the recent attribution of a portrait of the young Edward Talbot dated 1586 to Custodis.In 1591, he was living in the parish of St Bodolph-without-Aldgate where "Jacobus the son of Ieronyme Custodis A Paynter" was baptised on 2 March. He is assumed to have died in 1593, as all of his known works are dated between 1589 and 1593, and his widow remarried that year. Custodis's unsigned but dated works are idenitified by "palaeographical peculiarities" in the inscriptions which can be closely matched to those in his signed portraits.
