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 :. | The adoration of the Konige | The Virgin and Child with St Anne | The Virgin and St Anne (mk08) | The Annunciation | Mona Lisa (detail) dhu |

MEI, Bernardino
Italian painter, Roman school (b. 1612, Siena, d. 1676, Roma) Italian painter, draughtsman and printmaker. His early art drew on a variety of sources, which included the naturalism of Rutilio Manetti and Francesco Rustici, the descriptive realism of the engraver Giuliano Periccioli (d 1646) and the Baroque of Raffaelle Vanni. Mei's interests even embraced 16th-century Sienese art. This stylistic variety is evident in his first known works, such as a bier (Casole d'Elsa, Collegiata), three signed miniatures in the Libro dei leoni (1634; Siena, Pal. Piccolomini, Archv Stato) and frescoes of scenes from the Life of St Bernard (1639; Siena, oratory of S Bernardino). His experimental approach is also displayed in such works as the Annunciation (Siena, Mus. Semin. Montarioso), which may be dated between the mid-1630s and the early 1640s. Mei's early maturity is marked by a conscious return to the naturalism of Manetti, enriched with a Baroque pathos and soft, fluid brushwork, as in the St Peter in Prison Awoken by the Angel and St Peter Freed by the Angel (both Siena; Conservatori Femminili Riuniti). His interest in both naturalism and the Baroque made him responsive to the art of Mattia Preti, possibly seen in Rome, as in the Beheading of St John the Baptist (1647; Siena, oratory of S Giovannino in Pantaneto) and the frescoes of scenes from the Life of St Roch and Life of St Job (1648; Siena, S Rocco),
Otto Marseus van Schrieck
(ca. 1619, Nijmegen - buried June 22, 1678, Amsterdam) was a painter in the Dutch Golden Age. Marseus van Schrieck spent the years 1648-1657 in Rome and Florence with the painters Matthias Withoos and Willem van Aelst, after which he settled in Amsterdam. He is best known for his paintings of forest flora and fauna. In Arnold Houbraken's biography of him, he mentions that he joined the Bentvueghels in Rome and was called the snuffelaer, or "sniffer", because he was always sniffing strange lizards and snakes. He quotes his wife, who apparently survived him by two husbands and was still alive when he wrote the book. He wrote that she said that Otto kept snakes and lizards in a shed at the back of his house, and also on a piece of land outside the city that was walled in for this purpose.
