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 Annunciation | Virgin of the Rocks (mk10) | Bacchus (mk05) | Leda |

BORGIANNI, Orazio
Italian Baroque Era Painter, 1578-1616 Orazio Borgianni (c. 1575 - buried 15 January 1616) was an Italian painter and etcher of the Mannerist and early-baroque periods. He was the stepbrother of the sculptor and architect Giulio Lasso. Borgianni was born in Rome, where he was documented in February 1604. He was instructed in the art of painting by his brother, Giulio Borgiani, called Scalzo. The patronage by Philip II of Spain induced him to visit that Spain, where he signed an inventory in January 1605. He returned to Rome from Spain after April 1605 at the height of his career, and most of the work of his maturity was carried out 1605-16. In Spain, he signed a petition to begin an Italianate academy of painting and executed a series of nine paintings for the Convento de Portacoeli, Valladolid, where they remain. From his time in Spain, there remain two of his paintings in the Prado Museum: St Christopher and the Stigmatization of St Francis. On his return to Rome he was patronized by the Spanish ambassador, for whom he painted several pictures, and he was also employed in painting for the churches. He painted as late as 1630. after which he returned to Spain. He frescoed in the apse of the church of San Silvestro in Capite in Rome, a Martyrdom of S.Stefano I and a Messengers of Constantine call on Saint Silvestro (1610). His canvas of San Carlo Borromeo in the church of San Carlo alle Quattro Fontane (1612) is an eclectic and emotive synthesis of both Carracci and tenebrist styles. The influence of Caravaggio is also evident in a painting of the same saint (1616) now in the Hermitage Museum. A lively self-portrait of an earnest, somewhat foppish Borgianni is in the Rome Galleria Nazionale d'Arte Antica.
Jeronymus van Diest
(1631, The Hague - ca.1687, The Hague), was a Dutch Golden Age seascape painter. According to Houbraken, a Jeronymus van Diest was good with grisailles and was the teacher of Adriaen van de Venne.[1] This grisaille painter Jeronymus Diest (I) may possibly have been a grandfather of the younger Jeronymus Diest (II); since they are both from the Hague. According to the RKD this younger Jeronymus Diest (II) was the son of the painter Willem van Diest and the father of the painter Adriaen van Diest who was a follower of Jan van Goyen and Hendrik Dubbels.His known works are all seascapes with various ships at sail.
