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 :. | Study fur the adoration of the Konige | Mona Lisa (detail) r y | Madonna with the Yarnwinder | Last Supper (mk08) | Leda and the Swan |

BASSA, Ferrer
Spanish painter active 1324-1348 His workshop was in Calle Cucurulla, Barcelona, and commissions from a variety of patrons, mostly royal, are documented. In 1324 he was paid for painting two chapels and two crosses for the church at Sitges. Between c. 1333 and c. 1335 he illuminated a book on the Usages of Barcelona and Customs of Catalonia for Alfonso IV of Aragon, and in 1335 he was paid for an altarpiece. Further payments, in 1339 and 1340, were for two altarpieces for the chapel of the Aljaferea Palace (a Moorish palace) in Saragossa. About 1340 he received a commission for an altarpiece of St Hilary for the diocese of Lleida (Sp. Lerida). In 1341 Bassa had begun work on three altarpieces for the Episcopal See at Lleida, commissioned by Ot de Montacada (c. 1290-1341). In 1342 Peter IV (the Ceremonious) of Aragon asked his wife, Maria of Navarre, to send him a Book of Hours illuminated by Ferrer Bassa, and in the same year the artist was also paid for a commission by Queen Constanza of Mallorca. In 1343 and 1344 he was paid for an altarpiece and other works for the chapel of the Aljaferea Palace in Saragossa and for an altarpiece for the chapel of the royal palace at Barcelona. In 1344 Bassa was commissioned to decorate the S Miguel Chapel, then the cell of the abbess in the Pedralbes Monastery, Barcelona, although he only started work in 1346. He was involved in further royal commissions in 1345, including an altarpiece for the chapel of the castle at Perpignan.
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.
