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 :. | Cecila Gallerani (mk45) | Madonna in the rock grottos(Details | Battle of Anghiari | Head and shoulders Christs | The Virgin and Child with St Anne ey |

Guido da Siena
Italian Byzantine Style Painter, 13th Century He may have made significant advances in the techniques of painting, much as Cimabue much later accomplished. However, there is some debate about this. Guido is primarily known for a painting which is now split into several pieces. The church of S. Domenico in Siena contains a large painting of the Virgin and Child Enthroned with six angels above. The Benedictine convent of the same city has a triangular pinnacle representing the Saviour in benediction, with two angels. This was once a portion of the same composition, which was originally a triptych. The principal section of this picture has a rhymed Latin inscription, giving the painter's name as Guido de Senis, with the date 1221. However, this may not be genuine, and the date may really read as 1281. There is nothing particular to distinguish this painting from other work of the same period except that the heads of the Virgin and Child are much superior ?C in natural character and graceful dignity ?C to anything painted before Cimabue. As a result, there is some dispute as to whether these heads are really the work of a man who painted in 1221, long before Cimabue. Crowe and Cavalcaselle have proposed that the heads were repainted in the 14th century, perhaps by Ugolino da Siena. If Crowe and Cavalcaselle are right, Cimabue maintains his claim to the advancement of the art. Beyond this, little is known of Guido da Siena. A picture in the Academy of Siena is attributed to him (a half-figure of the Virgin and Child, with two angels), which dates (probably) between 1250 and 1300.
Maria Sibylla Merian
German Baroque Era Illustrator, 1647-1717,Daughter of Mattheus Merian. After her father's death, her mother married in 1651 the flower still-life painter Jacob Marell, who became Maria Sibylla's teacher. On 16 May 1665 she married Johann Andreas Graff, another pupil of her stepfather. She thenceforth specialized in illustrations of flowers, fruit and, especially, grubs, flies, gnats and spiders. In 1670 the family moved to Nuremberg. In 1675 Sandrart referred to her in the Teutsche Academie, reporting that she painted on cloth (i.e. silk, satin). With Graff, she produced a book of flowers, the first part appearing in 1675; a second edition, enlarged by parts 2 and 3 ,came out in 1680, entitled Florum fasciculi tres. It included 36 engravings intended to serve as patterns for embroidery.
