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 Last Supper | Annunciation (detail) ey79 | The Virgin and Child with St Anne | Madonna with the Yarnwinder | Grotesque profile of a man |

Juan Martin Cabezalero
1633-1673 was a Spanish draftsman and painter. Born in Almaden, he studied under Juan Carreno de Miranda, court painter to Charles II of Spain; Cabezalero lived at Carreno de Miranda's house until 1666. Both he and Carreno were influenced by Van Dyck. Few works by Cabezalero have survived. His surviving works include his St Jerome (1666, Meadows Museum, Southern Methodist University, Dallas) and the Assumption of the Virgin (ca. 1670; Madrid, Prado). The latter had been formerly attributed to Mateo Cerezo, also a pupil of Carreno de Miranda. Antonio Palomino praises Cabezalero's modest, studious nature and laments that he died young.
Frederick Stuart Church
Painter , Illustrator and Artist . American , 1842-1924 was an American artist, working mainly as an illustrator and especially known for his (often allegorical) depiction of animals. He was born in Grand Rapids, Michigan. His father was an important figure in politics as well as a well-known lawyer. At the age of 13 he left school and took a job at the then newly-established American Express Company in Chicago, with his parents intending him to have a business career. Being nineteen at the outbreak of the Civil War he served in the Union Army. After his discharge he returned to Chicago, having decided to devote his life to art, and started studying drawing under Walter Shirlaw at the city's Academy of Design. In 1870 he took the decision to continue his studies in New York City, which became his home for the rest of his life. He enrolled at the National Academy of Design, where he was taught by Lemuel Wilmarth. He joined the Art Students League, headed by his old teacher Walter Shirlaw, in which he remained involved for the rest of his life. Unlike many other Americans of his time who felt themselves to be living in a cultural backwater, Church - while he did think that an artist needed to be formally taught - saw no need to study art in Europe and in fact only crossed the Atlantic late in his life. He often expressed outspoken pride in original American art and declaring that "foreign art" had "little to teach Americans". This might be a reflection of the attitudes taken by the strong nativist movements active during his young age, among other places in Chicago when he lived there.
