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 :. | Study fur the Trivulzio-monument | Study fur the communion | Madonna in the rock grotto | Leda h | The Last Supper (detail) sg |

Gerrit van Honthorst
1590-1656 Dutch Gerrit Van Honthorst Galleries Gerard van Honthorst (November 4, 1592 - April 27, 1656), also known as Gerrit van Honthorst and Gherardo della Notte, was a Dutch painter of Utrecht. He was brought up at the school of Abraham Bloemaert, who exchanged the style of the Franckens for that of the pseudo-Italians at the beginning of the 16th century. Margareta Maria de Roodere and Her Parents by Gerrit van Honthorst (1652) Oil on canvas, 140 x 170 cm. Centraal Museum, UtrechtInfected thus early with a mania which came to be very general in the Netherlands, Honthorst went to Italy in 1616, where he copied the naturalism and eccentricities of Michelangelo da Caravaggio. Home again about 1620, after acquiring a considerable practice in Rome, he set up a school at Utrecht which flourished exceedingly. Together with his colleague Hendrick ter Brugghen, he represented the so-called Dutch Caravaggisti. In 1623 he was president of his gild at Utrecht, where he had married his cousin. He soon became so fashionable that Sir Dudley Carleton, then English envoy at The Hague, recommended his works to the earl of Arundel and Lord Dorchester. In 1626 he received a visit from Rubens, whom he painted as the honest man sought for and found by Diogenes. The queen of Bohemia, sister of Charles I of England and electress palatine, being in exile in the Netherlands, gave Honthorst her countenance and asked him to teach her children drawing; and Honthorst, thus approved and courted, became known to her brother Charles I, who invited him to England in 1628. There he painted several portraits, and a vast allegory, now at Hampton Court, of Charles and his queen as Diana and Apollo in the clouds receiving the duke of Buckingham as Mercury and guardian of the king of Bohemia's children. Charles I, whose taste was flattered alike by the energy of Rubens and the elegance of Van Dyck, was thus first captivated by the fanciful mediocrity of Honthorst, who though a poor executant had luckily for himself caught, as Lord Arundel said, much of the manner of Caravaggio's colouring, then so much esteemed at Rome.
Hans Vredeman de Vries
(1527 - c. 1607) was a Dutch Renaissance architect, painter, and engineer. Vredeman de Vries is known for his publication in 1583 on garden design and his books with many examples on ornaments (1565) and perspective (1604). Born in Leeuwarden and raised in Friesland, in 1546 Vredeman de Vries went to Amsterdam and Kampen. In 1549 he moved to Mechelen where the Superior Court was seating. Sebastian, his brother, was the organist in the local church. Vredeman de Vries designed ornaments for merry parades of Charles V and Philip II. Studying Vitruvius and Sebastiano Serlio, (translated by his teacher Pieter Coecke van Aelst), he became an internationally known specialist in perspective. He continued his career in Antwerp, where he was appointed city architect and fortification engineer. After 1585 he fled the city because of the Spanish occupation by Alessandro Farnese. Then the Protestants had to leave the city within two years. Vredeman de Vries moved to Frankfurt and worked in Wolfenbettel, designing a fortification and a new lay-out of the city for Julius, Duke of Brunswick-Leneburg. After his death the project was cancelled and Hans worked in Hamburg, Danzig (1592), Prague (1596) and Amsterdam (1600). On his trips Vredeman was accompanied by his son Paul and Hendrick Aerts. Vredeman de Vries tried to get an appointment at the University of Leiden in 1604. It is not known when and where Hans Vredeman de Vries died, however, it is recorded that his son Paul was living in Hamburg when he inherited.
william holman hunt,o.m.,r.w.s
1827-1910 English painter. He worked as an office clerk in London from 1839 to 1843, attending drawing classes at a mechanics' institute in the evenings and taking weekly lessons from the portrait painter Henry Rogers. Holman Hunt overcame parental opposition to his choice of career in 1843, and this determined attitude and dedication to art could be seen throughout his working life. In July 1844, at the third attempt, he entered the Royal Academy Schools. His earliest exhibited works, such as Little Nell and her Grandfather (exh. British Institution, 1846; Sheffield, Graves A.G.), reveal few traces of originality, but the reading of John Ruskin's Modern Painters in 1847 was of crucial importance to Holman Hunt's artistic development. It led him to abandon the ambitious Christ and the Two Marys (Adelaide, A.G. S. Australia) in early 1848, when he realized its traditional iconography would leave his contemporaries unmoved. His next major work, the Flight of Madeline and Porphyro during the Drunkenness Attending the Revelry (1848; London, Guildhall A.G.), from John Keats's 'Eve of St Agnes', though displaced into a medieval setting, dramatized an issue dear to contemporary poets and central to Holman Hunt's art: love and youthful idealism versus loyalty to one's family. His first mature painting, it focuses on a moment of psychological crisis in a cramped and shallow picture space.
