Question: Passage: The company, retaining the title "Sadler's Wells Opera", opened at the Coliseum on 21 August 1968, with a new production of Mozart's Don Giovanni, directed by Sir John Gielgud. Though this production was not well received, the company rapidly established itself with a succession of highly praised productions of other works. Arlen died in January 1972, and was succeeded as managing director by Lord Harewood.The success of the 1968 Mastersingers was followed in the 1970s by the company's first Ring cycle, conducted by Goodall, with a new translation by Andrew Porter and designs by Ralph Koltai.  The cast included Norman Bailey, Rita Hunter and Alberto Remedios. In Harewood's view, among the highlights of the first ten years at the Coliseum were the Ring, Prokofiev's War and Peace, and Richard Strauss's Salome and Der Rosenkavalier.
The company's musical director from 1970 to 1977 was Charles Mackerras. Harewood praised his exceptional versatility, with a range "from The House of the Dead to Patience." Among the operas he conducted for the company were Handel's Julius Caesar starring Janet Baker and Valerie Masterson; five Janáček operas; The Marriage of Figaro with pioneering use of 18th century performing style; Massenet's Werther; Donizetti's Mary Stuart with Baker; and Sullivan's Patience. The company took the production of the last to the Vienna Festival in 1975, along with Britten's Gloriana. Sir Charles Groves succeeded Mackerras as musical director from 1978 to 1979, but Groves was unwell and unhappy during his brief tenure. Starting in 1979, Mark Elder succeeded Groves in the post, and described Groves "immensely encouraging and supportive".A long-standing concern of Arlen and then Harewood was the need to change the company's name to reflect the fact that it was no longer based at Sadler's Wells theatre. Byam Shaw commented "The one major setback the Sadler's Wells Opera Company suffered from its transplant was that unheeding taxi drivers kept on taking their patrons up to Rosebery Avenue".Harewood considered it an elementary rule that "you must not carry the name of one theatre if you are playing in another one." Covent Garden, protective of its status, objected to the suggestion that the Sadler's Wells company should be called "The British National Opera" or "The National Opera", although neither Scottish Opera nor the Welsh National Opera opposed such a change. Eventually the British government decided the matter, and the title "English National Opera" was approved. The company's board adopted the new name in November 1974. In 1977, in response to demand for more opera productions in English provincial cities, a second company was established. It was based at Leeds in northern England, and was known as ENO North. Under Harewood's guidance, it flourished, and in 1981 it became an independent company, Opera North. 
Question: What is the first name of the person who unwell and unhappy during his brief tenure?

Answer: Charles.


Question: Passage: Throughout the early years of the July Monarchy, Alkan continued to teach and play at public concerts and in eminent social circles. He became a friend of many who were active in the world of the arts in Paris, including Franz Liszt (who had been based there since 1827), George Sand, and Victor Hugo. It is not clear exactly when he first met Frédéric Chopin, who arrived in Paris in September 1831. In 1832 Alkan took the solo role in his first Concerto da camera for piano and strings at the Conservatoire. In the same year, aged 19, he was elected to the influential Société Académique des Enfants d'Apollon (Society of the Children of Apollo), whose members included Luigi Cherubini, Fromental Halévy, the conductor François Habeneck, and Liszt, who had been elected in 1824 at the age of twelve. Between 1833 and 1836 Alkan participated at many of the Society's concerts. Alkan twice competed unsuccessfully for the Prix de Rome, in 1832 and again in 1834; the cantatas which he wrote for the competition, Hermann et Ketty and L'Entrée en loge, have remained unpublished and unperformed.In 1834 Alkan began his friendship with the Spanish musician Santiago Masarnau, which was to result in an extended and often intimate correspondence which only came to light in 2009. Like virtually all of Alkan's correspondence, this exchange is now one-sided; all of his papers (including his manuscripts and his extensive library) were either destroyed by Alkan himself, as is clear from his will, or became lost after his death. Later in 1834 Alkan made a visit to England, where he gave recitals and where the second Concerto da camera was performed in Bath by its dedicatee Henry Ibbot Field; it was published in London together with some solo piano pieces. A letter to Masarnau and a notice in a French journal that Alkan played in London with Moscheles and Cramer, indicate that he returned to England in 1835. Later that year, Alkan, having found a place of retreat at Piscop outside Paris, completed his first truly original works for solo piano, the Twelve Caprices, published in 1837 as Opp. 12, 13, 15 and 16. Op. 16, the Trois scherzi de bravoure, is dedicated to Masarnau. In January 1836, Liszt recommended Alkan for the post of Professor at the Geneva Conservatoire, which Alkan declined, and in 1837 he wrote an enthusiastic review of Alkan's Op. 15 Caprices in the Revue et gazette musicale. 
Question: Whose cantatas written for the competition, Hermann et Ketty and L'Entrée en loge, have remained unpublished and unperformed?

Answer: Alkan.


Question: Passage: Apart from pieces purely in metal, a number are centred on either hardstone carvings or organic objects such as horns, seashells, ostrich eggshells, and exotic plant seeds.  These "curiosities" are typical of the taste of the Renaissance "age of discovery" and show the schatzkammer and the cabinet of curiosities overlapping.  A different form of novelty is represented by a table-ornament of a silver-gilt foot-high figure of a huntsman with a dog and brandishing a spear.  There is a clockwork mechanism in his base which propels him along the table, and his head lifts off to show a cup, and he would have been used in drinking games. There are separate figures of a boar and stags for him to pursue, though not making a set; these can also function as cups.One of the most important objects in the collection is the Ghisi Shield, a parade shield never intended for use in battle, made by Giorgio Ghisi, who was both a goldsmith and an important printmaker.  It is signed and dated 1554. With a sword hilt, dated 1570 and now in at the Hungarian National Museum in Budapest, this is the only surviving damascened metalwork by Ghisi. The shield is made of iron hammered in relief, then damascened with gold and partly plated with silver. It has an intricate design with a scene of battling horseman in the centre, within a frame, around which are four further frames containing allegorical female figures, the frames themselves incorporating minute and crowded subjects on a much smaller scale from the Iliad and ancient mythology, inlaid in gold.Other major pieces are sets of a ewer and basin, basin in this context meaning a large dish or salver, which when used were carried round by pairs of servants for guests to wash their hands without leaving the table.  However the examples in the collection were probably hardly ever used for this, but were intended purely for display on sideboards; typically the basins are rather shallow for actual use.  These were perhaps the grandest type of plate, with large surfaces where Mannerist inventiveness could run riot in the decoration.  They were already expensive because of the weight of the precious metal, to which a huge amount of time by highly skilled silversmiths was added. The Aspremont-Lynden set in the bequest is documented in that family back to 1610, some 65 years after it was made in Antwerp, and weighs a little less than five kilos. 
Question: What city was  the Aspremont-Lynden set made?

Answer:
Antwerp.
