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-l | Virgin and Child with St Anne | Reverse side of the portrait of Ginevra de' Benci | Mona lisa | The Annunciation-o |

Francesco Hayez
1791-1882 Italian Francesco Hayez Galleries Hayez came from a relatively poor family from Venice. His father was of French origin while his mother, Chiara Torcella, was from Murano. The child Francesco, youngest of five sons, was brought up by his mother sister, who had married Giovanni Binasco, a well-off shipowner and collector of art. From childhood he showed a predisposition for drawing, so his uncle apprenticed him to an art restorer. Later he became a student of the painter Francisco Magiotto with whom he continued his studies for three years. He was admitted to the painting course of the New Academy of Fine Arts in 1806, where he studied under Teodoro Matteini. In 1809 he won a competition from the Academy of Venice for one year of study at the Accademia di San Luca in Rome. He remained in Rome until 1814, then moved to Naples where he was commissioned by Joachim Murat to paint a major work depicting Ulysses at the court of Alcinous. In the mid 1830s he attended the Salotto Maffei salon in Milan, hosted by Clara Maffei (whose portrait Hayez painted for her husband), and he was still in Milan in 1850 when he was appointed director of the Academy of Brera there. Assessment of the career of Hayez is complicated by the fact that he often did not sign or date his works. Often the date indicated from the evidence is that at which the work was acquired or sold, not of its creation. Moreover he often painted the same compositions several times with minimal variations, or even with no variation. His early works show the influence of Ingres and the Nazarene movement. His later work participates in the Classical revival.
