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 :. | Virgin and Child with St Anne | Portrait of Cecilia Gallarani | Study of a child | Madonna and Child with a Pomegranate | Flower Studies |

Boris Kustodiev
1878-1927 Russian Boris Kustodiev Galleries The Russian Revolution of 1905, which shook the foundations of society, evoked a vivid response in the artist's soul. He contributed to the satirical journals Zhupel (Bugbear) and Adskaya Pochta (Hell??s Mail). At that time, he first met the artists of Mir Iskusstva (World of Art), a group of innovative Russian artists. He joined their association in 1910 and subsequently took part in all their exhibitions. In 1905, Kustodiev first turned to book illustrating, a genre in which he worked throughout his entire life. He illustrated many works of classical Russian literature, including Nikolai Gogol's Dead Souls, The Carriage, and The Overcoat; Mikhail Lermontov's The Lay of Tsar Ivan Vasilyevich, His Young Oprichnik and the Stouthearted Merchant Kalashnikov; and Leo Tolstoy's How the Devil Stole the Peasants Hunk of Bread and The Candle. In 1909, he was elected into Imperial Academy of Arts. He continued to work intensively, but a grave illness??tuberculosis of the spine??required urgent attention. On the advice of his doctors he went to Switzerland, where he spent a year undergoing treatment in a private clinic. He pined for his distant homeland, and Russian themes continued to provide the basic material for the works he painted during that year. In 1918, he painted The Merchant's Wife, which became the most famous of his paintings. The Merchant's Wife, (1918).In 1916, he became paraplegic. "Now my whole world is my room", he wrote. His ability to remain joyful and lively despite his paralysis amazed others. His colourful paintings and joyful genre pieces do not reveal his physical suffering, and on the contrary give the impression of a carefree and cheerful life. His Pancake Tuesday/Maslenitsa (1916) and Fontanka (1916) are all painted from his memories. He meticulously restores his own childhood in the busy city on the Volga banks. In the first years after the Russian Revolution of 1917 the artist worked with great inspiration in various fields. Contemporary themes became the basis for his work, being embodied in drawings for calendars and book covers, and in illustrations and sketches of street decorations. His covers for the journals The Red Cornfield and Red Panorama attracted attention because of their vividness and the sharpness of their subject matter. Kustodiev also worked in lithography, illustrating works by Nekrasov. His illustrations for Leskov's stories The Darner and Lady Macbeth of the Mtsensk District were landmarks in the history of Russian book designing, so well did they correspond to the literary images.
