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 :. | Mona Lisa (mk08) | Female head (La Scapigliata) wt | The Annunciation | Madonna in the cave | Studies fur the adoration of the Konige |

Nebbia, Cesare
Italian, 1536-1614 Italian painter and draughtsman. He was a pupil of GIROLAMO MUZIANO and much influenced by Federico Zuccaro, and Vasari cited him as a promising painter. Between 1562 and 1575 Nebbia was continuously employed in Orvieto, producing altarpieces and frescoes in the cathedral, for example the Marriage at Cana (1569), the Crucifixion (1574) and the Crowning with Thorns (1575; all Orvieto, Mus. Opera Duomo). In Rome, where from 1579 his name appeared in the register of the Accademia di S Luca, he executed an Ecce homo and another Crowning with Thorns (1576; oratory of the Gonfalone), a Noli me tangere (1579; S Maria degli Angeli), decorations in the Sforza Chapel, S Maria Maggiore (1582), Heraclius Taking the Cross (1582-4; Santissimo Crocifisso), the Martyrdom of St Lawrence (1589; S Susanna) and decorations in the Borghese Chapel, Trinit? dei Monti (c. 1590). Under Pope Sixtus V he was responsible, with Giovanni Guerra, for the decorations in the Sistine Library, and he also worked on the Scala Santa, in the Vatican Palace and in the Lateran Palace. In 1597 he was principal of the Accademia di S Luca. Two years later he received payment for the cartoons of St Matthew and St Mark for the mosaics in the cupola of St Peter's. The following year he painted the Dream of Constantine (S Giovanni in Laterano). In 1603-4 he decorated, with Zuccaro, the hall in the Collegio Borromeo, Pavia. He retired to Orvieto in 1609.
Jacob Philipp Hackert
(September 15, 1737 - April 28, 1807) was a landscape painter from Brandenburg, who did most of his work in Italy. Hackert was born in 1737 in Prenzlau in the Margraviate of Brandenburg (now in Germany). He trained with his father Philipp (a portraitist and painter of animals) and his uncle, before going to the Akademie der Kenste in Berlin in 1758. Later he traveled to Swedish Pomerania and Stockholm, where he painted murals. He spent from 1765 to 1768 in Paris, with the Swiss Artist, Balthasar Anton Dunker, where he focused on painting in gouache. He met and was inspired by Claude Joseph Vernet, who was already famous as a painter of landscapes and seascapes, and the German engraver Johann Georg Wille. In 1768 Hackert left Paris with his brother Georg, and went to Italy, basing himself mainly in Rome and Naples, where he produced many works for Sir William Hamilton. He travelled all over Italy, gaining a reputation as a talented landscape painter. In 1786 he went to work for Ferdinand I of the Two Sicilies in Naples. He advised on the creation of a painting restoration laboratory at the Museo di Capodimonte, and supervised the transfer of the Farnese collections from Rome to Naples. By this time he had an international reputation, and won commissions from empress Catherine II of Russia, king Louis XVI of France and others. When Goethe visited Naples in 1786, he and Hackert became friends.
Karel Purkyne
(1834-1868) was a Czech painter. He was one of the most prominent proponents of realism in Czech art in the second half of the 19th century. He was the son of the physiologist and anatomist Jan Evangelista Purkyne, and developed an interest in art while still young. Early influences included the Baroque painters Karel Škreta and Petr Brandl and the paintings of the Dutch Golden Age. He spent a year in Munich studying with Johann Baptist Berdelle before traveling to Paris, where he worked with Thomas Couture; there he copied paintings by Old Masters and encountered the work of contemporary French artists. He was particularly struck by the works of Gustave Courbet. Upon returning to Prague, Purkyne became known primarily as a portraitist, though a handful of works in other genres are known. He also made a name for himself as an organizer of artistic events and as an art critic.
