Question: Question: Who ruled Egypt in the Fourth Dynasty? Passage:Azurite is unstable in air, however it was used as a blue pigment in antiquity. Azurite is naturally occurring in Sinai and the Eastern Desert of Egypt. It was reported by F. C. J. Spurrell (1895) in the following examples; a shell used as a pallet in a Fourth Dynasty (2613 to 2494 BCE) context in Meidum, a cloth over the face of a Fifth Dynasty (2494 to 2345 BCE) mummy also at Meidum and a number of Eighteenth Dynasty (1543–1292 BCE) wall paintings. Depending on the degree of fineness to which it was ground, and its basic content of copper carbonate, it gave a wide range of blues. It has been known as mountain blue or Armenian stone, in addition it was formerly known as Azurro Della Magna (from Italian). When mixed with oil it turns slightly green. When mixed with egg yolk it turns green-grey. It is also known by the names blue bice and blue verditer, though verditer usually refers to a pigment made by chemical process. Older examples of azurite pigment may show a more greenish tint due to weathering into malachite. Much azurite was mislabeled lapis lazuli, a term applied to many blue pigments. As chemical analysis of paintings from the Middle Ages improves, azurite is being recognized as a major source of the blues used by medieval painters. Lapis lazuli (the pigment ultramarine) was chiefly supplied from Afghanistan during the Middle Ages, whereas azurite was a common mineral in Europe at the time. Sizable deposits were found near Lyons, France. It was mined since the 12th century in Saxony, in the silver mines located there.

Question: Question: Of the Wagner operas that Vogl had roles in, which was written first? Passage:He played the role of Loge in Richard Wagner's Das Rheingold at Munich Court Opera on September 22, 1869, with his wife, Therese Vogl, playing the role of Wellgunde. He also played the role of Siegmund in Wagner's Die Walküre, also at Munich, on June 26, 1870. Therese Vogl played the role of Siegmund's sister and lover Sieglinde in the same performance.

At Bayreuth, he played the role of Loge in the first complete Ring cycle on August 13, 1876. His performance in the role caused fellow singer Lilli Lehmann to comment that he was born for the part and that his Loge had never been equalled. His debut at the Metropolitan Opera was in the title role of Lohengrin on January 1, 1890, and he also sang Loge, Siegmund, the title role of Tannhäuser, Tristan in Tristan und Isolde, and Siegfried in both Siegfried and Götterdämmerung at the Met. Heinrich Vogl was also the first performer to play the roles of Loge and Siegfried in London, which he did in the first Ring cycle in London at Her Majesty's Theatre, with Anton Seidl conducting and his wife playing the role of Brünnhilde.
