(10 August 1749 - 8 May 1828) was a Danish painter. He was the instructor of Martinus Rørbye. Christian August Lorentzen was born on 10 August 1749 as the son of a watchmaker. He arrived in Copenhagen around 1771 where he frequented the Royal Academy of Fine Arts but it is unclear whether he received formal training.From 1779 to 1782 he want abroad to develop his skills, visiting the Netherlands, Antwerp and Paris where he copied old masters. In 1792 he traveled to Norway to paint prospects. In a number of painting, such as Slaget på Reden (1801, Danish Museum of National History and Den rædsomste nat (1807, Danish National Gallery, he documented key events from the English Wars between 1801 and 1814. Later in his career he mainly painted portraits, landscapes and scenes from Ludvig Holberg's comedies. As a professor at the Royal Academy in Copenhagen from 1803 and until his death in 1828, he exercisized great influence on the next generation of painters such as Martinus Rørbye among others.  Related Paintings of Christian August Lorentzen :. | Peter Norden Solling | Fox in the Poultry Yard | Johan Frederik Classen | Dannebrog falling from the sky during the Battle of Lyndanisse | Parti af Frederiksholms Kanal |

Joseph Heintz the Elder
the Elder (Basle, 11 June 1564 - near Prague, Bohemia, October 1609) was a Swiss painter, draftsman and architect. He appears to have been a pupil of Hans Bock, and to have educated himself by diligent practice in copying the works of Hans Holbein the younger. Between 1585 and 1587 he lived in Rome, registering himself a pupil; to Hans von Aachen. He next settled in Bohemia in 1591, and was at once appointed court painter to Rudolf II, but he remained in Prague for two years only, as in 1593 he was commissioned to make some copies from the antique for the emperor, and for that purpose went to Rome, where he spent some years. In 1604 we hear of him in Augsburg, and from the time we know little of his history, until his decease is recorded in a village outside of Prague. Heintz's paintings included religious images, portraits, and, following the emperor's taste, erotic mythological themes. They were at one time in high demand, but later on suffered an eclipse. Among them are a family portrait in Berne and that of Rudolf II in Vienna. He was constantly investigating subtle questions of light, and almost all of his landscapes show the interest he took in this technical matter. A notable work by him is the Rape of Proserpine, which hangs in the Dresden Gallery, and was engraved by Lukas Kilian; in the same gallery are two other works, Lot and His Daughters and Ecce Homo. Finally there is his portrait of Constance of Austria. He had a son, who bore the same name, and who painted a few religious pictures; several of these works hitherto attributed to the son are now believed to be late productions by the father.
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.
Branwell Bronte
26 June 1817 - 24 September 1848) was a painter and poet, the only son of the Brontë family, and the brother of the writers Charlotte, Emily, and Anne. Branwell Brontë was the fourth of six children and the only son of Patrick Brontë and his wife, Maria Branwell Brontë. He was born in Thornton, near Bradford, Yorkshire, and moved with his family to Haworth when his father was appointed to the perpetual curacy in 1821. Of the four Brontë siblings who survived into adulthood, Branwell Brontë seems to have been regarded within the family as the most talented, at least during his childhood and youth. While four of his five sisters were sent to Cowan Bridge boarding school (resulting in the death of his two oldest sisters, Maria and Elizabeth, from tuberculosis), Branwell was kept at home to be privately educated by his father, who gave him a classical education suitable for admission to Oxford or Cambridge. Elizabeth Gaskell, biographer of his sister, Charlotte Bronte, says this of Branwell's schooling:
