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 | Profile of an old man | Study fur the Sforza-Reiterstandbild | St John in the Wilderness | Battle of Anghiari |

Ventura Salimbeni
(also later called Bevilacqua; 20 January 1568 - 1613) was an Italian Mannerist painter and printmaker and among the last representatives of a style influenced by the earlier Sienese School of Quattrocento-Renaissance. Salimbeni was born in Siena. He studied painting, together with his half-brother Francesco Vanni, under their father Arcangelo Salimbeni in his native Siena, He possibly spent some time,in Northern Italy and then moved to Rome in 1588 to work, together with others, on the fresco painting of the Vatican Library under pope Sixtus V. During 1590-1591, he got a commission by Cardinal Bonifazio Bevilacqua Aldobrandini for paintings in the Roman Jesuit Church of the Gese and the Basilica di Santa Maria Maggiore. These paintings show the influence of the Mannerist Cavalier D'Arpino and Andrea Lillio. Salimbeni returned to Siena in 1595. Here he became one of the last leaders of the Mannerist school, in this period between Mannerism and Baroque. He was here influenced by Federico Barocci as can be seen in the draperies, highlighted with abrupt changes of light and flickering surfaces, of his painting "Birth of a Virgin" in the San Domenico church in Ferrara (1607-1608). He completed painting cycles (1595-1602) for Sienese churches such as the oratory in the Santa Trinite. He is known for detailed preparatory drawings, most of which are now in the Uffizi in Florence or the Fine Arts Museum of San Francisco. He started around 1600 painting the scenes from the "Life of St. Hyacinth" for the Sienese church of Santo Spirito. These paintings show the awkward perspective of the style of the Sienese Mannerist painter Beccafumi in the backdrop of buildings and landscape. In Siena, Salimbeni completed several painting cycles for the church of Santo Spirito. He continued to create paintings for churches throughout Italy, including Florence. At the Basilica della Santissima Annunziata di Firenze, he frescoed lunettes (1605-1608) illustrating events in the history of the Servite Order. In the Duomo di San Salvatore, he executed a magnificent John the Baptist. At about the same time, around 1600, he got an assignment in Assisi for a fresco of the "Resurrection of Christ" and the "Dying Saint Clare is visited by the pope" in the vault of chapel of San Massimo in the Basilica of Santa Maria degli Angeli. Salimbeni got in 1603 the commission to paint frescoes with scenes from the church's patron saints in the church of Quirico and Giulitta, one of the oldest churches in Siena. As in the church of Santa Trinite, he worked here alongside with the painter Alessandro Casolari. This was a period on non-stop new assignments : three paintings for the church San Lorenzo in San Pietro in Montalcino, the "Donation of the Keys" (1599), the "Disputa of the Eucharist" (1600) and the "Crucifixion" (1604). At the same time he was painting the "Vision of Gregory the great" and the "Punishment of David" in the Basilica of San Pietro in Perugia. The papal legate, cardinal Bonifazio Bevilacqua (1571-1627), who had commissioned these paintings, was so pleased that he invested Ventura Salimbeni with the Order of the Golden Spur, a very selective papal order. He was even authorized from now on to name himself Cavalieri Bevilacqua. He painted the canvas of the Ascension of the Virgin (1607) for San Frediano in Pisa. In 1612 he painted the "Life of Saint Galganus" for the Chiesa del Santuccio in Siena with the hermit saint set in a wooded landscape. His last work of art was the oil painting the "Marriage of the Virgin" for the Seminario diocesano in Foligno in 1613.
Cristobal Rojas
Cristobal Rojas (Cua, Miranda, 15 December 1857 e Caracas, 8 November 1890) was one of the most important and high-profile Venezuelan painters of the 19th century. Rojas's styles varied considerably throughout his life, and he displayed talents in painting that ranged primarily for dramatic effect, to works done in the Impressionist style. Cristebal Rojas Poleo was born in the city of Cea in the Valles del Tuy to parents who worked in the medical profession. Part of his childhood occurred during the middle of the federal war (1859 - 1863) and Cea was particularly affected by the events of the war. He initiated studies under his grandfather, Jose Luis Rojas, who taught him how to draw and motivated him to improve. At 13 years old, his father died and he was forced to begin work in a tobacco factory in Cea to help support his family. In 1878, an earthquake devastated the Valles del Tuy region, and the Rojas faced poverty. As a result he moved to Caracas where he continued his painting studies, despite again having to work in the tobacco industry to support his mother and family. In Caracas he attended classes by Jose Manuel Mauco at the Universidad Central de Venezuela. Between 1880 and 1882, he developed a keen interest in oils and displayed a primitive technique that would prevail in his later paintings such as Ruinas de Cea despues del Terremoto and Ruinas del templo de la Merced. During this time he became acquainted with the painter Antonio Herrera Toro, also coming under contract as Toro's assistant to paint Caracas Cathedral.
