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 | Mona Lisa | Madonna with the Yarnwinder | Annunciation (detail) fg47 | Virgin of the Rocks,completed (mk08) |

FOSCHI, Pier Francesco
Italian painter, Florentine school (b. 1502, Firenze, d. 1567, Firenze) was an Italian painter active in Florence in a Mannerist style. He was pupil of Andrea del Sarto and assisted Pontormo with his frescoes at Careggi in 1536. He completed 3 altarpieces, commissioned in 1540C1545 for the church of Santo Spirito in Florence: an Immaculate Conception, Resurrection , and a Transfiguration. Foschi was also influenced by and Il Bronzino. One of his pupils was Alessandro Fei. Also called Pier Francesco di Jacopo Foschi or Toschi. He was the son of Pierfrancesco di Jacopo Sandro Foschi, known for his Madonna and Child with the Infant Saint John. (Utah Museum of Fine Arts). Foschi is best noted for his portraits painted between 1530 and 1540, including his Portrait of a Lady (Museo Thyssen-Bornemisza), Portrait of a Young Man Weaving a Wreath of Flowers (Utah Museum of Fine Arts), and his Portrait of a Man, (Uffizi Gallery). In his portraits he adhered to Mannerist style, utilizing a slight Contrapposto in the sitter with their head turned from the body. This pose gave the depiction a spontaneity and sense of movement for the innovative Mannerists, but was eventually so formulaic that it lost its intention of originality.
Cornelis Janssens van Ceulen
(also Cornelius Jonson van Ceulen, Cornelius Johnson, Cornelis Jansz. van Ceulen and many other variants)(bapt. October 14, 1593, London - bur. August 5, 1661, Utrecht) was an English painter of portraits of Dutch or Flemish parentage. He has been described as "one of the most gifted and prolific portrait painters practising in England during the 1620s and 1630s". Janssens van Ceulen was born to Dutch or Flemish parents in London - his father had been a refugee from Antwerp, and the family had originated in Cologne. He was baptised at the Dutch church at Austin Friars, the son of Johanna le Grand and Cornelius Johnson. He may have been trained in the Netherlands, and was certainly influenced by other artists from the Netherlands, but he was active in England, at least from 1618 to 1643. In the 1620s, he lived and had his studio in Blackfriars, London, as did Anthony van Dyck; it was just outside the boundaries of the City of London, and so avoided the monopoly in the City of members of the London painters' Guild. He married Elizabeth Beke of Colchester in 1622. Janssens' son (Cornelius Janssens, junior) was born in 1634. He was also a painter. Janssens' daughter was married to Nicholas Russell of Bruges. Janssens moved to Canterbury in the mid 1630s, living with Sir Arnold Braems, a Flemish merchant. Janssens continued to live in England until after the outbreak of the English Civil War, but in October 1643, apparently at the insistence of his wife, he moved to Middelburg, and between 1646 and 1652 he lived in Amsterdam, before settling in Utrecht, where he was buried.
