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 :. | Annunciation (detail) dfe | Madonna with the carnation | You branching of the Blutgefabe, anatomical figure with heart kidneys and Blutgefaben | Profile of an old man | Study of the proportion of horses |

Antonio Ciseri
(October 25, 1821 ?C March 8, 1891) was a Swiss painter of religious subjects. Ciseri was born in Ronco sopra Ascona in the canton of Ticino in Switzerland. In 1833 he moved with his father to Florence. He was admitted in 1834 to the Accademia di Belle Arti, where he trained under Niccola Benvenuti. In 1849, he began offering instruction to young painters, and eventually ran a private art school. Among his earliest students was Silvestro Lega.[1] Ciseri's religious paintings are Raphaelesque in their compositional outlines and their polished surfaces, but are nearly photographic in effect. He fulfilled many important commissions from churches in Italy and Switzerland. Ciseri also painted a significant number of portraits. He died in Florence on March 8, 1891.
Giovanni Migliara
Italian 1785-1837 He began his career as a scene painter with Gaspare Galiari (1761-1823) in Milan, working at the Teatro Carcano in 1804 and at La Scala from 1805 to 1809. Owing to illness, after 1810 he turned to small-scale works in watercolour or oil using various supports, including silk and ivory. At this date Milanese painting was dominated by Andrea Appiani and Luigi Sabatelli, both leading Neo-classical artists. However, Migliara remained aloof from this dominant movement and instead drew on medieval and historical subjects with Romantic undertones. His precise, jewel-like technique and choice of subject-matter found favour with aristocratic patrons in Milan. His figures are generally stilted and burdened by their costumes, though the crowd in Sacking of Minister Prina's House (1814; Milan, Gal. A. Mod.) is depicted with unusual fluency. In 1822 Migliara was appointed Professor of Perspective at the Accademia di Belle Arti, Milan, and in 1833 he was nominated painter to the court of Charles-Albert, King of Sardinia (reg 1831-49). More typical of his historical scenes is Entrance to the Castle of Plessis de la Tour (Turin, Gal. Civ. A. Mod.), which was exhibited at the Brera in 1833. He also produced many topographically precise pictures of church interiors in which he combined his training as a scene painter with his knowledge of intaglio techniques.
Thomas Girtin
English Romantic Painter, 1775-1802 English painter, draughtsman and printmaker. With his rival, J. M. W. Turner, he extended the technical possibilities of watercolour and in doing so demonstrated that watercolours could have the visual impact and emotional range of oils. Although close in style throughout the 1790s, by 1800 Turner and Girtin were beginning to diverge: whereas the former dissolved forms to express his idea of Nature in a state of flux, the latter sought out a landscape's underlying patterns to convey his awe of Nature's permanence as well as its grandeur.
