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 :. | Study fur the Sforza-Reiterstandbild | Profiles of a young and an old man | Study Fur the Trivulzio-monument | Annunciation (detail) dg | Mona Lisa (La Gioconda) sdg |

Telemaco signorini
Italian Painter, 1835-1901 was an Italian artist who belonged to the group known as the Macchiaioli. He was born in the Santa Croce quarter of Florence, and showed an early inclination toward the study of literature, but with the encouragement of his father, Giovanni Signorini, a court painter for the Grand Duke of Tuscany, he decided instead to study painting. In 1852 he enrolled at the Florentine Academy, and by 1854 he was painting landscapes en plein air. The following year he exhibited for the first time, showing paintings inspired by the works of Walter Scott and Machiavelli at the Florentine Promotrice. In 1855, he began frequenting the Caffe Michelangiolo in Florence, where he met Giovanni Fattori, Silvestro Lega, and several other Tuscan artists who would soon be dubbed the Macchiaioli. The Macchiaioli, dissatisfied with the antiquated conventions taught by the Italian academies of art, started painting outdoors in order to capture natural light, shade, and color. They were forerunners of the Impressionists who, beginning in the 1860s, would pursue similar aims in France. Signorini was a volunteer in the Second Italian War of Independence in 1859, and afterwards painted military scenes which he exhibited in 1860 and 1861. He made his first trip outside Italy in 1861 when he visited Paris, to which he would often return in the decades that followed. There he met Degas and a group of expatriate Italian artists in his orbit, including Giovanni Boldini, Giuseppe De Nittis, and Federico Zandomeneghi; unlike them, however, Signorini remained rooted in Italy. He became not only one of the leading painters of the Macchiaioli, but also their leading polemicist. Art historian Giuliano Matteucci has written: "If we acknowledge Fattori and Lega as the major creative figures of the macchiaioli, then Signorini must surely be recognized as their 'deus ex machina'",
Harriet Backer
Norwegian Painter, 1845-1932 Norwegian painter. In the 1860s and early 1870s she took lessons in drawing and painting in Christiania (now Oslo) and also travelled extensively in Europe with her sister Agathe, a composer and pianist. She copied works in major museums and took occasional art lessons; she later considered this experience to have been of fundamental importance to her artistic development. Little Red Riding Hood (1872; Oslo, N.G.) is impressive in technique, and the early portrait of her sister, Agathe Backer-Grendahl (1874; Holmestrand, Komm.), shows a refined colour scheme. At the age of nearly 30 Backer decided to train professionally as a painter and in 1874 went to Munich. She was never attached to a particular institution, but the influence of her friend the artist Eilif Peterssen was crucial to her development. In Munich she made a thorough study of perspective, which formed a secure basis for her later work.
