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 :. | Madonna Benois Madonna with a Flower | Adoration of the Magi | Madonna of the Rocks | Portrait of Cecilia Gallarani | The Virgin of the Rocks |

Koloman Moser
Koloman Moser (German pronunciation: [ˈkoːloman ˈmoːzɐ]) (March 30, 1868 - October 18, 1918) was an Austrian artist who exerted considerable influence on twentieth-century graphic art and one of the foremost artists of the Vienna Secession movement and a co-founder of Wiener Werkstätte. During his life, Moser designed a wide array of art works - books and graphic works from postage stamps to magazine vignettes; fashion; stained glass windows, porcelains and ceramics, blown glass, tableware, silver, jewelry, and furniture - to name a few of his interests. Born in Vienna, he studied at the Wiener Akademie and the Kunstgewerbeschule, where he also taught from 1899. His designs in architecture, furniture, jewelry, graphics, and tapestries helped characterize the work of this era. Moser drew upon the clean lines and repetitive motifs of classical Greek and Roman art and architecture in reaction to the Baroque decadence of his turn-of-the-century Viennese surroundings. In 1901/1902, he published a portfolio titled Die Quelle ("The Source") of elegant graphic designs for such things as tapestries, fabrics, and wallpaper. In 1903, Moser and his colleague Josef Hoffmann founded Wiener Werkstätte, whose studios and artisans produced a number of aesthetically and functionally designed household goods, including glassware, flatware, silverware, and textiles. In 1904, he created the Apse mosaic and glass windows for the Kirche am Steinhof in Vienna. Steinhof Church commemorative coin In 1905, together with the Klimt group, he separated from the Vienna Secession. The same year, he married Editha (Ditha) Mautner von Markhof, the daughter to one of Austria's great industry fortunes. In 1907 Kolo Moser, due to internal conflicts and as his plans for reorganising the Werkstätte (to cope with financial problems) weren't realised, withdrew from the Wiener Werkstätte. Koloman was one of the designers for Austria's leading art journal Ver Sacrum. This art journal paid great attention to design and was designed mainly by Moser, Gustav Klimt and Josef Hoffmann.
BREGNO, Andrea
Italian Early Renaissance Sculptor and Architect, 1418-1503 Andrea Bregno was invited to move from Venice to Rome when the Venetian Paul II was elected Pope. During the pontificate of the Della Rovere Pope Sixtus IV he received many commissions and headed a large workshop, producing many wall tombs of cardinals and other figures of the papal curia with varying degrees of personal responsibility. He was famous among his contemporaries, and was compared to the Greek sculptor Polykleitos in the epitaph of his tomb in Santa Maria sopra Minerva. Raphael's father, Giovanni Santi, mentioned Bregno in the 1480s, in his biography of Federico da Montefeltro, duke of Urbino. Bregno often worked with Mino da Fiesole in Rome, and his refined Lombard manner was rendered more classical by the contact and by the example of Roman sculptures that were increasingly coming to light, of which Andrea Bregno was an early collector: a certain "Prospettivo Milanese", writing in 1499-1500 refers to a torso in the collection of a "Maestro Andrea" that seems to have been the Belvedere Torso. He moved in humanist circles and was an esteemed friend of the humanist in Sixtus' circle, Bartolomeo Platina, the librarian of the Vatican Library. Bregno played a significant role in the standardization of an authentically classicizing style of epigraphy, in the inscriptions that accompany his tombs. In the Sistine Chapel he collaborated with Mino da Fiesole and Giovanni Dalmata to produce the little cantoria or choristers' gallery set into the wall, with its own coffered ceiling and carved marble balusters, and the marble screen.
Robert Nanteuil
1623-78 French engraver, draughtsman and pastellist. He was the son of Lancelot Nanteuil, a wool merchant, and submitted his thesis in philosophy, for which he engraved the headpiece, at the Jesuit College of Reims, in 1645. He went on to work in the studio of Nicolas Regnesson, whose sister he married in 1646, before moving to Paris in 1647. His early work mainly consisted of portrait drawings in black lead on parchment (e.g. Paris, Louvre), and he continued to draw throughout his career. He took 155 of his 221 portraits directly from life. His drawing style was influenced by Philippe de Champaigne, and he based his engraving technique on the work of Claude Mellan and Jean Morin. By 1652 he had developed his own technique
