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 :. | The Last Supper sgu | The Benois Madonna | Madonna with the Yarnwinder | Studies of horses | Annunciation |

MANTEGNA, Andrea
Italian Early Renaissance Painter, ca.1431-1506 Italian painter and printmaker. He occupies a pre-eminent position among Italian artists of the 15th century. The profound enthusiasm for the civilization of ancient Rome that infuses his entire oeuvre was unprecedented in a painter. In addition to its antiquarian content, his art is characterized by brilliant compositional solutions, the bold and innovative use of perspective and foreshortening and a precise and deliberate manner of execution, an aspect that was commented upon during his lifetime. He was held in great esteem by his contemporaries for his learning and skill and, significantly, he is the only artist of the period to have left a small corpus of self-portraits: two in the Ovetari Chapel; his presumed self-portrait in the Presentation in the Temple (Berlin, Gemeldegal.); one in the Camera Picta (Mantua, Pal. Ducale) and the funerary bust in his burial chapel in S Andrea, Mantua, designed and probably executed by himself. His printmaking activity is technically advanced and of great importance, although certain aspects of the execution remain to be clarified.
k. e. jansson
Karl Emanuel Jansson, född 7 juli 1846 i Finström, Åland, död 1 juni 1874 i Jomala, var en åländsk konstnär. Han var näst äldst av sju syskon. Han far, Jan Jansson, var en bonde i Pålsböle. Sina konstnärliga inspiration fick han av sockenmålaren G Kjellgren, vid sex-sju års ålder, när han där lärde sig att läsa och skriva. Efter avlutad skolgång sattes han i skomakarlära. Efter ett år drogs han till Kjellgren och fungerade som hans hjälpreda. Kyrkoherden Frans von Knorring såg i slutet av 1859 några av hans teckningar. Han sände några till Finska Konstföreningens direktion och lovordade Karl. Förening gav ett bidrag för att kunna studera vid Finska Konstföreningens ritskola i Åbo, under ledning av Robert Wilhelm Ekman. Av Ekman fick han husrum, rit- och målningsmaterial och en hel del extra undervisning. Karl gjorde stora framsteg under de 2 åren han målade med Ekman. Jansson flyttade hösten 1862 till Stockholm, för att kunna utvecklas mer som artist, och inskrevs som elev vid Kongl. Akademin för de fria konsterna. Han tog anatomiexamen 1863. Han levde under svåra ekonomiska förhållanden och hade svårt att sälja sina verk. Jansson fick hård kritik för de målningar han sände hem, exempelvis, Babian ätande en råtta, och konstföreningen betraktade dem med avsky. Han började då kritisera sig själv allt mer och mer, och den inställningen behöll han. Han fick inte den uppmärksammad han behövde. Tavlan Den förlorade sonens återkomst, belönades med ett pris. Han avslutade sin utbildning vid akademien 1867 med mycket beröm. Jansson lyckades utverka statsstöd för studier i Dusseldorf och reste dit på hösten 1868. Han åkte hem igen sommaren 1870 och tillbringade ett år på Åland innan han återvände till Dusseldorf. Han var nu märkt av en tilltagande lungsjukdom. De sista verk han fullbordade var Talmannen och En slant i håven. För att lindra sin sjukdom reste han till Rom i mars 1872. Efter några månader åkte han runt till olika kurorter (Davos, Meran) men inget förbättrade hans tillstånd. Efter en liten tid i D??sseldorf kom han hem till Åland sensommaren 1873. Karl flyttade in på Jomala gård, där lagman Lönnblad och hans fru tog hand om honom. Han målade några verk, vilka blev ofullbordade. På dödsbädden fick han veta att han belönats på världsutställningen i Wien för sina konstverk Klöveress och Talmannen, samt att han blivit medlem i konstakademin i Sankt Petersburg. Han dog 1 juni 1874, inte ens fylld 28 år.
