[EX Q]: 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 (15431292 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.

He became mayor of Barcelona and commander in chief of Catalonia during the Siege of Barcelona until he was wounded in combat while commanding La Coronela during the counterattack on the Saint Peter front on the last day of the siege, September 11, 1714. After the war he received a royal pardon for having supported the Habsburg claim to the Spanish throne. He recovered from his wounds, and continued his fight against absolute monarchy as a lawyer. It has been claimed that he is the author of the book Record de l'Alianca fet el Serenissim Jordi Augusto Rey de la Gran Bretanya (Remembrance of the Alliance to George I of Great Britain) in which Catalonia reminds England of the Treaty of Genoa and their obligation to Catalonia.
