Q: Given the following context:  By the summer of 1906, Mahler had been director of the Vienna Hofoper for nine years. Throughout this time his practice was to leave Vienna at the close of the Hofoper season for a summer retreat, where he could devote himself to composition. Since 1899 this had been at Maiernigg, near the resort town of Maria Wörth in Carinthia, southern Austria, where Mahler built a villa overlooking the Wörthersee. In these restful surroundings Mahler completed his Symphonies No. 4, No. 5, No. 6 and No. 7, his Rückert songs and his song cycle Kindertotenlieder ("Songs on the Death of Children").Until 1901, Mahler's compositions had been heavily influenced by the German folk-poem collection Des Knaben Wunderhorn ("The Youth's Magic Horn"), which he had first encountered around 1887. The music of Mahler's many Wunderhorn settings is reflected in his Symphonies No. 2, No. 3 and No. 4, which all employ vocal as well as instrumental forces. From about 1901, however, Mahler's music underwent a change in character as he moved into the middle period of his compositional life. Here, the more austere poems of Friedrich Rückert replace the Wunderhorn collection as the primary influence; the songs are less folk-related, and no longer infiltrate the symphonies as extensively as before. During this period Symphonies No. 5, No. 6 and No. 7 were written, all as purely instrumental works, portrayed by Mahler scholar Deryck Cooke as "more stern and forthright ..., more tautly symphonic, with a new granite-like hardness of orchestration".Mahler arrived at Maiernigg in June 1906 with the draft manuscript of his Seventh Symphony; he intended to spend time revising the orchestration until an idea for a new work should strike. The composer's wife Alma Mahler, in her memoirs, says that for a fortnight Mahler was "haunted by the spectre of failing inspiration"; Mahler's recollection, however, is that on the first day of the vacation he was seized by the creative spirit, and plunged immediately into composition of the work that would become his...  answer the following question:  What is the piece that the who directed Vienna Hofoper for nine years created while vacationing at Maiernigg?
A: Eighth Symphony

Q: Given the following context:  By the time El Greco arrived in Rome, Michelangelo and Raphael were dead, but their example continued to be paramount, and somewhat overwhelming for young painters. El Greco was determined to make his own mark in Rome defending his personal artistic views, ideas and style. He singled out Correggio and Parmigianino for particular praise, but he did not hesitate to dismiss Michelangelo's Last Judgment in the Sistine Chapel; he extended an offer to Pope Pius V to paint over the whole work in accord with the new and stricter Catholic thinking. When he was later asked what he thought about Michelangelo, El Greco replied that "he was a good man, but he did not know how to paint". And thus we are confronted by a paradox: El Greco is said to have reacted most strongly or even condemned Michelangelo, but found it impossible to withstand his influence. Michelangelo's influence can be seen in later El Greco works such as the Allegory of the Holy League. By painting portraits of Michelangelo, Titian, Clovio and, presumably, Raphael in one of his works (The Purification of the Temple), El Greco not only expressed his gratitude but also advanced the claim to rival these masters. As his own commentaries indicate, El Greco viewed Titian, Michelangelo and Raphael as models to emulate. In his 17th century Chronicles, Giulio Mancini included El Greco among the painters who had initiated, in various ways, a re-evaluation of Michelangelo's teachings.Because of his unconventional artistic beliefs (such as his dismissal of Michelangelo's technique) and personality, El Greco soon acquired enemies in Rome. Architect and writer Pirro Ligorio called him a "foolish foreigner", and newly discovered archival material reveals a skirmish with Farnese, who obliged the young artist to leave his palace. On 6 July 1572, El Greco officially complained about this event. A few months later, on 18 September 1572, he paid his dues to the Guild of Saint Luke in Rome as a miniature painter. At the end of that year, El Greco opened his own workshop and...  answer the following question:  What is the name of the young artist who Farnese obliged to leave his palace?
A: El Greco

Q: Given the following context:  The Rokeby Venus (; also known as The Toilet of Venus, Venus at her Mirror, Venus and Cupid, or  La Venus del espejo) is a painting by Diego Velázquez, the leading artist of the Spanish Golden Age.  Completed between 1647 and 1651, and probably painted during the artist's visit to Italy, the work depicts the goddess Venus in a sensual pose, lying on a bed and looking into a mirror held by the Roman god of physical love, her son Cupid. The painting is in the National Gallery, London. Numerous works, from the ancient to the baroque, have been cited as sources of inspiration for Velázquez. The nude Venuses of the Italian painters, such as Giorgione's Sleeping Venus (c. 1510) and Titian's Venus of Urbino (1538), were the main precedents. In this work, Velázquez combined two established poses for Venus: recumbent on a couch or a bed, and gazing at a mirror. She is often described as looking at herself on the mirror, although this is physically impossible since viewers can see her face reflected in their direction. This phenomenon is known as the Venus effect. In a number of ways the painting represents a pictorial departure, through its central use of a mirror, and because it shows the body of Venus turned away from the observer of the painting.The Rokeby Venus is the only surviving female nude by Velázquez. Nudes were extremely rare in seventeenth-century Spanish art, which was policed actively by members of the Spanish Inquisition. Despite this, nudes by foreign artists were keenly collected by the court circle, and this painting was hung in the houses of Spanish courtiers until 1813, when it was brought to England to hang in Rokeby Park, Yorkshire. In 1906, the painting was purchased by National Art Collections Fund for the National Gallery, London. Although it was attacked and badly damaged in 1914 by the suffragette Mary Richardson, it soon was fully restored and returned to display.  answer the following question:  Who is often described as looking at herself on the mirror in the work?
A:
Venus
