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 madonna with the Children | Madonna in the rock grotto | Madonna with the Yarnwinder | Virgin of the Rocks | Madonna with the Yarnwinder |

Johann Jakob Ulrich
impression atist 28 Feb 1798 -- 17 March 1877. Swiss painter. He first studied under his father and then in Paris in 1822 in the studio of Jean-Victor Bertin. As a student he concentrated on unusual lighting effects in his landscape paintings well before they became a hallmark of the precursors of the Impressionists. In 1824 at the Salon in Paris he first saw paintings by Constable. On a trip to Italy in 1828 he did studies en plein air as preliminary sketches for his studio paintings. His early paintings emphasize brilliant colour, low horizons and scientific observation of cloud formations in a manner similar to Constable's studies, which he actually saw on visits to England in 1832 and 1835. Like Eugene Boudin, Ulrich was interested in poetic evocations of sun, water and effects of atmosphere rather than in the precise delineations of topography typical of Swiss art of that period. From 1824 he showed regularly at the Salons in Paris and in 1837 he returned to Zurich. Because the Swiss public was reluctant to accept his freer,

Johann Ludwig Aberli
Swiss, 1723-1786, Swiss painter, draughtsman and engraver. In 1741 he moved to Berne, where he took drawing lessons with Johann Grimm (1675-1747), whose school of drawing he took over in 1747. He visited the Bernese Oberland with Emanuel Handmann, Christian Georg Schetz (1718-91) and Friedrich Wilhelm Hirt (1721-72) in 1759 and in the same year travelled to Paris with Adrian Zingg (1734-86). This was his only trip abroad, but it determined him to work exclusively as a landscape painter. After nine months he returned to Berne, where his landscape views became popular, particularly with foreign travellers, enamoured of 'Nature' and keen to retain souvenirs of their travels. He was one of the first artists to portray the beauties of the Swiss countryside; his favourite subjects were the Aare Valley and views of Swiss lakes (e.g. View of Erlach on the Lake of Biel; Berne, Kstmus.). He invented a technique known as the 'Aberli style', which consisted of watercolour washes added to an image in which slightly smudged outlines were achieved through a combination of engraving and etching. The prints were made from drawings taken from nature and finished in the studio. His style was characterized by delicate execution, an intimate narrative approach, refined colours and the ability to convey a light and vaporous atmosphere. Aberli's success was such that he had to employ assistants and pupils to aid him in the coloration process; his pupils included Erasmus Ritter, Johann Jakob Biedermann, Marquard Wocher (1760-1830), Gabriel Ludwig Lory the elder (1763-1840) and Peter Birmann. From 1773 to 1775 Aberli also painted a series of costumes in response to tourist demand.
