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 :. | Lady with Emine | Portrait of Ginevra de' Benci | La Belle Ferronniere | Madonna of the Rocks | La Gioconda (The Mona Lisa) |

Peter Birmann
Swiss, 1758-1844,He began his career as a portrait painter in Basle and Pruntrut but in 1775 moved to Berne, where he took up landscape painting. From 1777 to 1781 he worked with Johann Ludwig Aberli and was also a colour-printer with the publisher Abraham Wagner (1734-82). In 1781 he went to Rome, where he remained for ten years working for Louis Ducros and for Giovanni Volpato. While in Rome he painted landscapes in watercolour and drew in bistre, using a soft brush and making little use of the pen. He also sketched in the Alban Hills, being particularly attracted to the waterfalls at Tivoli and Terni. He became a member of Goethe's circle in Rome, and, under the influence of its members, he adopted Claude as his model. His watercolours and bistre drawings, enlivened by Greco-Roman or contemporary staffage, became more tranquil, more classical in style and increasingly strengthened with pen outlines. In 1792 he returned to Basle to teach. He soon became an art dealer, opened his own shop and set up his own publishing house, and in 1802 he printed his best-known work, a series of aquatints of Voyage pittoresque de Basle ? Bienne par les vallons de Mottiers-Grandval. From 1802 to 1804 he showed at the annual exhibitions of the K?nstlergesellschaft in Zurich, and in 1804 and 1810 in Berne he exhibited work in oils, a medium that was becoming increasingly important for him. In 1805 he was commissioned by the publishing house of Artaria & Co. in Vienna to sketch the scenery in the region of the north Italian lakes. For the next 30 years he continued to paint and draw, but after 1834 he tended to repeat the locales and compositions of his earlier landscapes.
