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 | The Virgin and St Anne (mk08) | Portrait of Cecilia Gallerani | La belle Ferronire dg | Annunciation (detail) dg |

franz von schober
was a student in Vienna, where he met F. Schubert, E. Bauernfeld, and M. von Schwind. He is the author of twelve poems set to music by Schubert between 1815 and 1827, of which the best known is An die Musik (Du holde Kunst). In later life Schober was a secretary of legation (Legationsrat) in Weimar.
Thomas Sully
1783-1872 Thomas Sully Galleries Sully became a professional painter at age 18 in 1801. He studied face-painting under Gilbert Stuart in Boston for three weeks. After some time in Virginia with this brother, Sully moved to New York, after which he moved to Philadelphia in 1806, where he resided for the remainder of his life. In 1809 he traveled to London for nine months of study under Benjamin West. Sully's 1824 portraits of John Quincy Adams, who became President within the year, and then the Marquis de Lafayette appear to have brought him to the forefront of his day. (His Adams portrait may be seen in the National Gallery of Art, Washington.) Many famous Americans of the day had their portraits painted by him. In 1837-1838 he was in London to paint Queen Victoria at the request of Philadelphia's St. George's Society. His daughter Blanche assisted him as the Queen's "stand-in", modeling the Queen's costume when she was not available. One of Sully's portraits of Thomas Jefferson is owned by the Jefferson Literary and Debating Society at the University of Virginia and hangs in that school's Rotunda. Another Jefferson portrait, this one head-to-toe, hangs at West Point, as is his portrait of Alexander Macomb (American general). Sully's own index indicates that he produced 2631 paintings from 1801, most of which are currently in the United States. His style resembles that of Thomas Lawrence. Though best known as a portrait painter, Sully also made historical pieces and landscapes. An example of the former is the 1819 Passage of the Delaware, now on display at the Museum of Fine Arts, Boston.
Laura Theresa Alma-Tadema
(1852 C 15 August 1909 in Hindhead) was from 1871 the second wife of the painter Lawrence Alma-Tadema and a painter in her own right. A daughter of Dr George Napoleon Epps (who was brother of Dr John Epps), her two sisters were also painters (Emily studied under John Brett, a Pre-Raphaelite, and Ellen under Ford Madox Brown), whilst Edmund Gosse and Rowland Hill were her brothers-in-law. It was at Madox Brown's home that Alma-Tadema first met her in December 1869, when she was aged 17 and he 33. (His first wife had died in May that year.) He fell in love at first sight,and so it was partly her presence in London (and partly the fact that only in England had his work consistently sold) that influenced him into relocating in England rather than elsewhere when forced to leave the continent by the outbreak of the Franco Prussian War in July 1870. Arriving in London at the beginning of September 1870 with his small daughters and sister Artje, Alma-Tadema wasted no time in contacting Laura, and it was arranged that he would give her painting lessons. During one of these, he proposed marriage. As he was then thirty-four and Laura was now only eighteen, her father was initially opposed to the idea. Dr Epps finally agreed on the condition that they should wait until they knew each other better. They married in July 1871 and, though this second marriage proved childless, it also proved enduring and happy, with Laura acting as stepmother to her husband's children by his first marriage. The Paris Salon in 1873 gave Laura her first success in painting, and five years later, at the Paris International Exhibition, she was one of only two English women artists exhibited.
