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 :. | Abendmahl | Portrait of a Musician dey | Maria with Child and St. Anna | Profile of an old man | Mona Lisa |

Joseph Michael Gandy (1771 - 1843) was an English artist, visionary architect and architectural theorist, most noted for his imaginative paintings depicting Sir John Soane's architectural designs. He worked extensively with Soane both as draughtsman and creative partner from 1798 until 1809 when he (ultimately unsuccessfully) set up his own practice. Gandy built little in his career, having a reputation as a difficult individual to deal with. However his work included the Phoenix Fire and Pelican Life Insurance Offices (1804?C1805, destroyed ca. 1920) in London, Doric House at Sion Hill in Bath (1818), and the remodelling of Swerford Park house in Oxfordshire (1824?C1829). Commercially he was a failure and served two terms in a debtors' prison, but his published and exhibited work was largely a critical and popular success. In 1821 he published two articles in the Magazine of Fine Arts on The Philosophy of Architecture. He intended to expand upon this subject in an eight-volume work entitled Art, Philosophy and Science of Architecture, of which his unpublished manuscript survives. His paintings show a dramatic use of two-point perspective and architectural precision, and also reflect his (and Soane's) fascination with Roman ruins. His architectural fantasies owe a clear debt to Piranesi and play upon historical, literary and mythological themes with a feeling for the sublime that is the equal of his contemporaries J. M. W. Turner and John Martin. He died in a private asylum in Devon where he had been placed by his family in 1839. Many of his paintings can be seen in the Pictures Room of Sir John Soane's Museum in London.

Milan; feast day December 7) Bishop of Milan. Raised in Rome, he became a Roman provincial governor. As a compromise candidate, he was unexpectedly elevated from unbaptized layman to bishop of Milan in 374. He established the medieval concept of the Christian emperor as subject to episcopal advice and censure when he forced the emperor Theodosius to seek forgiveness from the bishop, and he opposed tolerance for adherents of Arianism. He wrote theological treatises influenced by Greek philosophy, including On the Holy Spirit and On the Duties of Ministers, as well as a series of hymns. His brilliant sermons and personal example converted St. Augustine.
Juriaen van Streeck
(1632 - 1687) was a Dutch Golden Age painter of still lifes. According to Houbraken, he was good at all sorts of still life subjects, including helmets, books, letters, musical instruments, and skulls or dead animals to indicate the transcience of life. He was a follower of Willem Kalf and influenced Barend van der Meer.Houbraken also wrote an entry for his son Hendrick van Streeck, who became a student of Emanuel de Witte and painted church interiors.
