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 of the Rocks | The Last Supper | Saint John the Baptist | Reverse side of the portrait of Ginevra de' Benci | Virgin and Child with St Anne |

Giulio Romano
Italian 1492-1546 Giulio Romano was born in Rome. In his native city, as a young assistant in Raphael's studio, he worked on the frescos in the Vatican loggias to designs by Raphael and in Raphael's Stanze in the Vatican painted a group of figures in the Fire in the Borgo (L'incendio di Borgo) fresco. He also collaborated on the decoration of the ceiling of the Villa Farnesina. After the death of Raphael in 1520, he helped complete the Vatican frescoes of the life of Constantine as well as Raphael's Coronation of the Virgin and the Transfiguration in the Vatican. In Rome, Giulio decorated the Villa Madama for Cardinal Giuliano de' Medici, afterwards Clement VII. The crowded Giulio Romano frescoes lack the stately and serene simplicity of his master. In the Palazzo Te, MantuaAfter the Sack of Rome in 1527 and the death of Leo X, artistic patronage in Rome slackened. Vasari tells how Baldassare Castiglione was delegated by Federico Gonzaga to procure Giulio to execute paintings and architectural and engineering projects for the duchy of Mantua. His masterpiece of architecture and fresco painting in that city is the suburban Palazzo Te, with its famous illusionistic frescos (c. 1525?C1535). He also helped rebuild the ducal palace in Mantua, reconstructed the cathedral, and designed the nearby Church of San Benedetto. Sections of Mantua that had been flood-prone were refurbished under Giulio's direction, and the duke's patronage and friendship never faltered: Giulio's annual income amounted to more than 1000 ducats. His studio became a popular school of art.
