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 :. | Lady with the ermine | You branching of the Blutgefabe, anatomical figure with heart kidneys and Blutgefaben | Study Fur the Trivulzio-monument | Portrat of a Madchens | The Madonna of the Carnation g |

Peter von Hess
(29 July 1792, Dseldorf - 4 April 1871, Menchen) was a German painter, known for historic paintings, especially of the Napoleonic Wars and the Greek War of Independence. Peter von Hess initially received training from his father Carl Ernst Christopher Hess. He accompanied his younger brother Heinrich Maria to Munich in 1806, and enrolled at the Munich Academy at the age of sixteenth. He also trained under Wilhelm von Kobell. During the Napoleonic Wars, he was allowed to join the staff of General Wrede, who commanded the Bavarians in the military operations which led to the abdication of Napoleon. There he gained novel experiences of war and a taste for extensive travel. During this time, von Hess painted his first battle pieces. In 1818 he spent some time in Italy where he painted landscapes and various Italian scenes. In 1833, at Ludwig's request, he accompanied Otto of Greece to the newly formed Kingdom of Greece, where at Athens he gathered materials for pictures of the war of liberation. The sketches which he then made were placed, forty in number, in the Pinakothek, after being copied in wax on a large scale by Nilsen, in the northern arcades of the Hofgarten at Munich. King Otho's entrance into Nauplia was the subject of a large and crowded canvas now in the Pinakothek, which Hess executed in person.
Miguel Cabrera
(1695-1768) was an indigenous Zapotec painter during the Viceroyalty of New Spain, today's Mexico. During his lifetime, he was recognized as the greatest painter in all of New Spain. He was born in Antequera, today's Oaxaca, Oaxaca, and moved to Mexico City in 1719. He may have studied under the Rodreguez Juerez brothers or Jose de Ibarra. Cabrera was a favorite painter of the Archbishop and of the Jesuit order, which earned him many commissions. His work was influenced by Bartolome Esteban Murillo and the French painting of his time. While Miguel is most famous for his Casta paintings and his portrait of the poet Sor Juana, he also executed one of the first portraits of St. Juan Diego. In 1752 he was permitted access to the icon of Our Lady of Guadalupe to make three copies: one for Archbishop Jose Manuel Rubio y Salinas, one for the Pope, and a third to use as a model for further copies. In 1756 he created an important early study of the icon of Our Lady of Guadalupe, Maravilla americana y conjunto de raras maravillas observadas con la direccien de las reglas del arte de la pintura The essential purpose of Maravilla Americana was to affirm the 1666 opinions of the witnesses who swore that the image of the Virgin was of a miraculous nature. However, he also elaborated a novel opinion: the image was crafted with a unique variety of techniques. He contended that the Virgin's face and hands were painted in oil paint, while her tunic, mandorla, and the cherub at her feet were all painted in egg tempera. Finally, her mantle was executed in gouache. He observed that the golden rays emanating from the Virgin seemed to be of dust that was woven into the very fabric of the canvas, which he asserted was of "a coarse weave of certain threads which we vulgarly call pita," a cloth woven from palm fibers. In 1753, he founded the second Academy of Painting in Mexico City and served as its director.
