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 :. | The Annunciation | Portrait of Cecilia Gallarani | Christ's Head | Detail of Madonna of the Rocks | Bacchus |

CAMPEN, Jacob van
Dutch Baroque Era Painter, 1595-1657 Chief exponent of Classicism in The Netherlands. He studied architecture in Italy and was influenced by the work of Scamozzi and Palladio. With his Coymans House on the Keizersgracht, Amsterdam (1624), he introduced the Palladian style to The Netherlands. His most refined work is the Mauritshuis in The Hague (1633?C5), which has a Palladian plan, elevations featuring a Giant Order of Ionic pilasters set on a plain base, a pedimented central section given little emphasis, and a hipped roof. Much grander is the Town Hall (now Royal Palace), Amsterdam (1648?C55): it has two internal courtyards separated by a huge central hall, façades with two superimposed Giant Orders of pilasters, and a large projecting pedimented central section over which is a domed lantern. His Nieuwe Kerk (New Church), Haarlem (1645?C9), is based on the quincunx plan (essentially a Greek cross within a square), with square Ionic crossing-piers and a groin-vault over the crossing. He was responsible for the Accijnshuis, Amsterdam (1638), the Noordeinde Palace, The Hague (1640), and, with others, the decorations of Post's Huis-den-Bosch, Maarssen, near Utrecht (c.1628).
Gaspare Diziani
(1689 - 17 August 1767) was an Italian painter of the late-Baroque or Roccoco period, active mainly in the Veneto but also in Dresden and Munich. His earliest training was in his native town of Belluno with Antonio Lazzarini, then moved to Venice, to the studio of Gregorio Lazzarini and later that of Sebastiano Ricci. He was seven years older, but otherwise his career was contemporary with the Lazzarini and Ricci fellow-pupil, Giovanni Battista Tiepolo. Between 1710-1720, he painted a group of eight pictures that included the Mary Magdalene for the church of San Stefano in Belluno, and Entry into Jerusalem for San Teodoro in Venice. He also painted three frescoes on the Life of Saint Helena in the Scuola del Vin next to the church of San Silvestro. Dizianies celerity and technical assurance are evident preparatory oil sketches, with color applied in rapid and spirited strokes. He was also working as a scenery painter for the theater and opera in Venice, Munich (1717), and later in Dresden, working with Alessandro Mauro. Diziani was invited to Rome by Cardinal Ottoboni in 1726, to paint a emagnificent decoration for the church of San Lorenzo in Damaso. The decoration is now known only through an engraving by Claude Vasconi. The Sala dei Pastelli in Ca' Rezzonico has an sotto in su allegorical ceiling fresco presenting Triumph of Poetry (Poetry surrounded by Painting, Architecture, Music and Sculpture).
