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 :. | Mona Lisa | Last Supper | The annunciation | The Baptism of Christ (detail) sg | Female head (La Scapigliata) wt |

Johann Wolfgang von Goethe
Frankfurt 1749-1832 Weimar,was a German writer and according to George Eliot, "Germany's greatest man of letters and the last true polymath to walk the earth." Goethe's works span the fields of poetry, drama, literature, theology, humanism and science. Goethe's magnum opus, lauded as one of the peaks of world literature, is the two-part drama Faust. Goethe's other well-known literary works include his numerous poems, the Bildungsroman Wilhelm Meister's Apprenticeship and the epistolary novel The Sorrows of Young Werther. Goethe was one of the key figures of German literature and the movement of Weimar Classicism in the late 18th and early 19th centuries; this movement coincides with Enlightenment, Sentimentality (Empfindsamkeit), Sturm und Drang and Romanticism. The author of the scientific text Theory of Colours, he influenced Darwin with his focus on plant morphology. He also served at length as the Privy Councilor ("Geheimrat") of the duchy of Weimar. Goethe is the originator of the concept of Weltliteratur ("world literature"), having taken great interest in the literatures of England, France, Italy, classical Greece, Persia, Arabic literature, amongst others. His influence on German philosophy is virtually immeasurable, having major effect especially on the generation of Hegel and Schelling, although Goethe himself expressly and decidedly refrained from practicing philosophy in the rarefied sense. Goethe's influence spread across Europe, and for the next century his works were a major source of inspiration in music, drama, poetry and philosophy. Goethe is considered by many to be the most important writer in the German language and one of the most important thinkers in Western culture as well.

Dutch Baroque Era Painter, 1636-1695 Dutch animal painter. His grandfather, Gillis d'Hondecoeter (d. 1638) and his father, Gysbert d'Hondecoeter (1604?C1653), were landscape and animal painters. After four years at The Hague, where he painted The Menagerie of William III at Loo, Melchior settled in Amsterdam. He painted all forms of animal life, but is best known for his depiction of birds and fowl, in which he has few equals. Representative works, executed in a smooth, precise style, include the Dead Cock
