LEONARDO da Vinci
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.

Winslow Homer Locations
Winslow Homer (February 24, 1836 ?C September 29, 1910) was an American landscape painter and printmaker, best known for his marine subjects. He is considered one of the foremost painters in 19th century America and a preeminent figure in American art.
Largely self-taught, Homer began his career working as a commercial illustrator. He subsequently took up oil painting and produced major studio works characterized by the weight and density he exploited from the medium. He also worked extensively in watercolor, creating a fluid and prolific oeuvre, primarily chronicling his working vacations. JACOBSZ, DirckFlemish Northern Renaissance Painter, ca.1497-1567
North Netherlandish painter, son of JACOB CORNELISZ. VAN OOSTSANEN. His birthdate is estimated from van Mander's claim that he died at the age of almost 70. His birthplace is unknown, but by about the age of three he was living in Amsterdam, where his father purchased a house in 1500. Dirck himself is documented in the city from 1546 until his burial. About 1550 he married Marritgen Gerritsdr., by whom he had two children, Maria Dircksdr. and Jacob Dircksz. War, also a painter. Dirck was trained by his father, probably around 1512, when Jan van Scorel was an apprentice. The two young artists may have remained friends, for in later years elements of Jan's mature, more Mannerist style can be seen in Dirck's paintings. Not only were Dirck's father and his brother, the little-known painter Cornelis Jacobsz. (d 1526-33), artists, his uncle Cornelis Buys I ( fl c. 1490-1524) Johannes Bosboom(born The Hague, February 18, 1817 - died there September 14, 1891) was a Dutch painter and watercolorist of the Hague School, known especially for his paintings of church interiors.
At the age of 14 he became a student of Bartholomeus van Hove and painted in his studio along with Van Hove's son Hubertus van Hove. Together they worked on the pieces of scenery that Van Hove created for the Royal Theatre in The Hague. In addition, Bosboom took lessons from 1831 to 1835 and again from 1839 to 1840 in the Hague Academy of Art. Here he also made the acquaintance of Antonie Waldorp and Wijnand Nuyen.
The young Bosboom traveled to Germany in 1835 to Dusseldorf, Cologne and Koblenz and painted the watercolor View of the Mosel Bridge at Koblenz. This painting was purchased by Andreas Schelfhout, who became his confidante and friend. In 1939 he traveled to Paris and Rouen and received a silver medal for View of the Paris Quay and the Cathedral at Rouen. He also painted a number of church interiors, a relatively traditional genre in which the seventeenth century artists Pieter Saenredam and Emanuel de Witte served as important examples. Bosboom had a great deal of success with these pieces, and for the rest of his career he would repeatedly return to this theme, which was the one in which he would achieve his greatest fame.
Bosboom's choice of subject matter may seem to isolate him from the rest of the Hague School, but his search for ways to reproduce the spatial atmosphere through light, shadow, and nuances of color places him in the very mainstream of this group. In 1873, during a stay in Scheveningen, he painted many watercolors of town views, the dunes, the beach and the sea. It is possible that these watercolors encouraged Hendrik Willem Mesdag and Jacob Maris to concentrate further on the sea and beach as subjects.
