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 :. | Portrait | Anatomical study of the brain and the scalp | The Baptism of Christ | The Baptism of Christ (detail) sg | Madonna in the rock grottos |

Peder Balke
Peter Andersen was born on the island of Helgøya, in Hedmark county, Norway. He grew up Ringsaker, but stayed in the 1820s on the Balke farm in Toten in Oppland county. Farmers in Toten paid his education, and as thanks he decorated several of the farms in Toten on his return. They actively encouraged his painting activities and later supported him in higher education. In the autumn of 1827, Balke served as an apprentice to Heinrich August Grosch. he was also a student at the Tegneskole under Grosch and Jacob Munch. Balke signed a two year contract as an apprentice at the Danish decoration and artist Jens Funch. From autumn 1829 to spring 1833, he was a pupil of Carl Johan Fahlcrantz at the art academy in Stockholm. Balke was also a pupil of Johan Christian Dahl from 1843 to 1844. During the summer of 1830 he walked through Telemark, Rjukan, Vestfjorddalen over Røldal and Kinsarvik to Bergen, and then back over Vossevangen to Gudvangen, further over Fillefjell to Valdres and thence across the mountains to Hallingdal. All the way he painted and drew small sketches that were later developed into paintings. He also traveled to Germany, and Russia. He visited Paris and London. In Stockholm, he completed several of the paintings he had outlined of his Finnmark tour. Some of these were sold to the royal family. In 1846 he sold thirty of his paintings to Louis-Philippe of France for Versailles. Besides the 17 paintings in the National Gallery in Oslo, Peder Balke also is represented at several major art collections in Norway and Sweden.
