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 :. | la scapigliata | Annunciation (detail) fg47 | Annunciation (detail) sg77 | The Refectory with the Last Supper after restoration g | Master of the Pala Sforzesca, profile of an old man |

MINDERHOUT, Hendrik van
Flemish painter (b. 1632, Rotterdam, d. 1696, Antwerpen). Dutch painter, active in the southern Netherlands. For unknown reasons, he was known as the 'Green Knight of Rotterdam'. In 1644 he married Margareta van den Broecke, and in 1652 he went to Bruges, where in 1663 he entered the Guild of St Luke; the marine painting that he submitted to the Guild to become a member used to be displayed in the Salle d'Acad?mie as a companion piece to the picture submitted by Rubens on his entry to the Guild. In 1672 van Minderhout moved to Antwerp, where he was admitted to the Guild the same year and where, in return for exemption from all obligations as a guild member, he presented a large canvas representing an Eastern seaport. In 1673 he married his second wife, Anna-Victoria Claus. They had five children, including two sons, Antoon van Minderhout (b 26 Sept 1675; d 22 Dec 1705) and Willem August van Minderhout (b 28 Aug 1680; d 31 June 1752), who also became painters. Hendrik van Minderhout painted mostly sea and harbour views, in the tradition of Jan Baptist Weenix and Johannes Lingelbach. His subjects included the port of Antwerp, as well as imaginary views of Mediterranean harbours and oriental seaports

Adriaen van der werff
Dutch Baroque Era Painter, 1659-1722 Dutch painter and draughtsman. He was apprenticed to the portrait painter Cornelis Picolet (1626-79) from 1668 to 1670 and then from c.1671 to 1676 to Eglon van der Neer in Rotterdam. From 1676 van der Werff produced small portraits and genre paintings as an independent master; the Cook and Hunter at a Window (1678; New York, priv. col.; see Gaethgens, no. 2) and Man and Woman Seated at a Table (1678; St Petersburg, Hermitage) perpetuate the thematic and stylistic traditions of Gerrit Dou, Gabriel Metsu, Frans van Mieris and Gerard ter Borch (ii) but are distinguished by their greater elegance and richness of costume and interior. Van der Werff's portraits date mainly from the years 1680-95 (e.g. Two Children with a Guinea-pig and a Kitten (1681; London, Buckingham Pal., Royal Col.)). The motif of children with animals recalls van der Neer, while the careful depiction of fabrics recalls the Leiden school of 'Fine' painters. His Portrait of a Man in a Quilted Gown (1685; London, N.G.) resembles compositions by Caspar Netscher and Nicolaes Maes: a figure leaning against a balustrade, before a landscape. Van der Werff's work is, however, more elegant, in part because of the depiction of fabrics
