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 Virgin and Child with Anne (mk05) | Virgin of the Rocks (mk10) | Horses with horsemen | Last Supper | Detail of Madonna of the Rocks |

Lorens Pasch the Younger
(1733-1805) was a Swedish painter He grew up in an artistic family (he was the brother of Ulrika Pasch, alongside whom he was elected to the Art Academy in 1773), but his father Lorens Pasch the Elder wanted him to become a priest. He was thus sent to study in Uppsala aged 10. However, he decided on an artistic career after all and began an apprenticeship in his father's studio before going to Copenhagen, with introductions from his wealthy and influential uncle Johan Pasch. There he studied painting for three years in the studio of Carl Gustaf Pilo. Despite good offers of studio-apprenticeships and commissions from Sweden, he then set off for Paris in 1758 to complete his artistic education. There he specialised in history painting in the studios of Eustache Le Sueur and François Boucher (though for financial reasons he also continued his training in portraiture) and became friends with fellow-Swede Alexander Roslin. In 1764 he left Paris and got back to Sweden in 1766. He fully completed his training in the studio of the French painter Guillaume Taraval, who in 1735 founded the Royal Swedish Academy of Arts in Stockholm. Soon after his arrival back in Sweden Pasch's gained a great reputation as a portraitist, gaining favour and commissions from the royal court and gaining the esteem of Adolf Frederick, King of Sweden and his queen Louisa Ulrika - one of his most notable works is his Portrait of Louisa Ulrika of Prussia. He served as a professor at the Academy of Arts from 1773 to his death, becoming its director on Pilo's death in 1793. At the end of his life he concentrated more on training young artists and managing the Academy than on painting. He died unmarried in 1805 and due to his powerful portraits remains one of the most respected painters of the Gustavian era in Sweden.
Jan Boeckhorst
Born in Westphalia, in either Menster or Rees, Boeckhorst moved to Antwerp around 1626. He had a close relationship with Rubens's studio, finishing paintings designed by that master as well as assisting with large series such as the joyous entry of Cardinal-Infante Ferdinand in 1635 and the Torre de la Parada. He also collaborated as a figure painter in landscapes and still lifes by Jan Wildens and Frans Snyders, and sometimes painted lively group portraits.[1] He traveled to Italy in the years 1635-1639 and joined the Bentvueghels with the nickname Lange Jan (Tall John). Cornelis de Bie, in his Gulden Cabinet der Edel Vry Schilderconst (The Golden Cabinet of the Honourable Free Art of Painting; 1662), remarks that Boeckhorst was a student of Jordaens. Works in that master's style include large genre paintings of the 1640s such as Peasants going to Market (Antwerp, Rubenshuis), which also acts as an allegory of the four elements. In the 1650s and 1660s Boeckhorst painted altarpieces for churches throughout Flanders and designed cartoons for tapestries.
