Leonardo Da Vinci
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.

Cosimo Rosselli Gallery
Born in Florence, at the age of fourteen he became a pupil of Neri di Bicci, and in 1460 he worked as assistant to his cousin Bernardo di Stefano Rosselli. A first youthful work of Cosimo mentioned by Giorgio Vasari is the Assumption of the Virgin altarpiece in the third chapel on the left of the nave in Sant'Ambrogio in Florence. In the same church, on the wall of one of the chapels, is a fresco by Cosimo which Vasari praises highly, especially for a portrait of the young scholar Pico of Mirandola. The scene, a procession bearing a miracle-working chalice, is painted with vigor and less mannerism than most of this artist's work. A picture painted by Rosselli for the church of the Annunziata, with figures of SS. Barbara, Matthew and the Baptist, is in the Academy of Florence.
Rosselli also spent some time in Lucca, where he painted several altar-pieces for various churches. A picture attributed to him, taken from the church of St. Girolamo at Fiesole, is now in the National Gallery of London. It is a large retable, with, in the center, St. Jerome in the wilderness kneeling before a crucifix, and at the sides standing figures of St. Damasus and St. Eusebius, St. Paula and St. Eustochium; below is a predella with small subjects. Though dry and hard in treatment, the figures are designed with much dignity.
The Berlin Gallery possesses three pictures by Rosselli: The Virgin in Glory, The Entombment of Christ, and The Massacre of the Innocents. In 1480 Rosselli, together with the chief painters of Florence, was invited by Pope Sixtus IV to Rome to assist in the painting of the frescoes in the Sistine Chapel. Three of these were executed by him The Destruction of Pharaohs Army in the Red Sea, Christ Preaching by the Lake of Tiberias, and The Last Supper. Rosselli's Sistine frescoes were partly painted by his assistant and son in law Piero di Cosimo, who was so called after Cosimo Rosselli. His chief pupil was Fra Bartolomeo.
According to Vasari, Rosselli died in 1484, but this is a mistake, as his is known to be living on 25 November 1506Marchetti
