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 :. | Anatomical studies of the basin of the Steibeins and the lower Gliedmaben of a woman and study of the rotation of the arms | Mona Lisa | Equestrian monument | Muscle structure of the thigh | The Madonna of the Carnation (detail) dg |

CARRACCI, Agostino
Italian Baroque Era Painter, 1557-1602 Painter, engraver and draughtsman, cousin of Ludovico Carracci. He abandoned his profession as a tailor, which was also that of his father, Antonio, and began training as a painter. According to Faberi, he studied first in the workshop of the painter Prospero Fontana (like Ludovico), then trained under the engraver and architect Domenico Tibaldi and under the sculptor Alessandro Menganti (1531-c. 1594). However, it is likely that Faberi's account was influenced by his desire to present Agostino's career as an example of the versatile 'cursus studiorum' advocated by the Accademia degli Incamminati. Other sources (Mancini, Malvasia, Bellori) agree that it was his cousin Ludovico who was responsible for directing him towards painting.
Anna Atkins
Tonbridge 1799-1871 Tonbridge,English botanist and pioneer of the photogram and photographic publishing. Daughter of the prominent scientist John George Children, Atkins was encouraged by him in her scientific interests. She was a competent watercolourist and published at least one lithograph. By 1823 her draughtsmanship and observational skills were refined enough for her to produce 200 illustrations for her father's translation of Lamarck's Genera of Shells. Botany was her particular love, especially the collection and study of seaweeds. Her father chaired the February 1839 Royal Society meeting at which Henry Talbot first revealed the manipulatory secrets of photogenic drawing. Father and daughter soon got a camera and took up the new art of photography, but Atkins's biggest contribution to it involved neither a camera nor her father. She conceived the idea of publishing a photographic record of her algae, making photograms by contact printing the dried specimens on sheets of sensitized paper.
After Jan de Baen
Jan de Baen (20 February 1633 - 1702) was a Dutch portrait painter who lived during the Dutch Golden Age. He was a pupil of the painter Jacob Adriaensz Backer in Amsterdam from 1645 to 1648. He worked for Charles II of England in his Dutch exile, and from 1660 until his death he lived and worked in The Hague. His portraits were popular in his day, and he painted the most distinguished people of his time.
