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 for the Trivulzio Equestrian Monument | Virgin of the Rocks | The Virgin of the Rocks | La Belle Ferronniere | Leda |

Louis Janmot
(21 May 1814 - 1 June 1892) was a French painter and poet. Janmot was born in Lyon of Catholic parents who were deeply religious. He was extremely moved by the death of his brother in 1823 and his sister's in 1829. He became student at the Royal College of Lyon where he met Frederic Ozanam and other followers of his philosophy professor, Abbe Noirot. In 1831 he was admitted to the École des Beaux-Arts de Lyon and a year later, he won the highest honor, the Golden Laurel. In 1833, he came to Paris to take painting lessons from Victor Orsel and Jean-Auguste-Dominique Ingres. With other Lyon painters, he entered the Society of St. Vincent de Paul. In 1835, he went to Rome with Claudius Lavergne, Jean-Baptiste Frenet and other students and met Hippolyte Flandrin. After his come back to Lyon in 1836, Janmot would attract the attention of critics of the Salon de Paris in conducting large-scale paintings with religious inspiration such as The Resurrection of the son of the widow of Nain (1839) or Christ in Gethsemane (1840). After 1845, he attracted the interest of Charles Baudelaire with his painting Flower of the Fields that allowed him to access to the Salon of 1846. Theophile Gautier was impressed by his Portrait of Lacordaire (1846). But the failure of his Poem of the Soul at the Universal Exhibition of 1855 disappointed him. In December of that year he married Leonie Saint-Paulet, from a noble family in Carpentras. In 1856, Janmot obtained a commission to paint a fresco (since destroyed) representing the Last Supper for the church of St. Polycarp. Other orders followed, including the decoration of the dome of the Church of St. Francis de Sales and for the town hall that had been renovated by his friend the architect T. Desjardins. He was then appointed professor at the École des Beaux-Arts.
