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 | The Annunciation | The Refectory with the Last Supper after restoration g | Madonna and Child with a Pomegranate et | Our Lady and St Anne |

GRAMATICA, Antiveduto
Italian Baroque Era Painter, 1571-1626 Italian painter. He was from a Sienese family. According to Baglione, his parents were journeying from Siena to Rome when his mother went into labour and gave birth to him at an inn, an inconvenience that had been foreseen ('antiveduto') by his father and led to his unusual name. For a brief period he was a pupil of Giandomenico Angelini ( fl 1550-1600), under whom he painted small-scale works, mainly on copper. His prolific production of devotional paintings, portraits and copies of portraits won him swift success; in 1593 he became a member of the Accademia di S Luca and in 1604 of the Congregazione dei Virtuosi. His early portraits have not been identified; they included highly popular copies of a series of Famous Men then at the Villa Medici, works that Caravaggio probably also copied when he worked for some months in his studio on his arrival in Rome in 1592

Franz Ludwig Catel
German Painter, 1778-1856,German painter. As a child, Catel helped carve small wooden figures in the toyshop owned by his father. With the encouragement of the printmaker Daniel Chodowiecki, Catel enrolled at the Berlin Kunstakademie, becoming a full member in 1806. In 1807, after already making a name for himself as a watercolourist and book illustrator, he began several years of study at the Acad?mie des Beaux-Arts in Paris, where his main subject was oil painting. In 1811 he moved to Italy, where he stayed for the rest of his life. Initially he wavered between Joseph Anton Koch's classically heroic style of landscape painting and the Romantic lyricism of the Nazarenes. Eventually he found that he could best exercise his technical ability, and most quickly achieve fame and fortune, by producing Italian landscapes. He specialized in Neapolitan scenes depicting festive folk customs; and such paintings proved popular with the mass of wealthy travellers who came to Italy after the Napoleonic Wars.
