Input: Consider Input: 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again in 1834; the cantatas which he wrote for the competition, Hermann et Ketty and L'Entrée en loge, have remained unpublished and unperformed.In 1834 Alkan began his friendship with the Spanish musician Santiago Masarnau, which was to result in an extended and often intimate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?

Output: Alkan.


Input: Consider Input: Passage: The building was sold in 1549 by Buonaccorso Pitti, a descendant of Luca Pitti, to Eleonora di Toledo.  Raised at the luxurious court of Naples, Eleonora was the wife of Cosimo I de' Medici of Tuscany, later the Grand Duke.  On moving into the palace, Cosimo had Vasari enlarge the structure to fit his tastes; the palace was more than doubled by the addition of a new block along the rear.  Vasari also built the Vasari Corridor, an above-ground walkway from Cosimo's old palace and the seat of government, the Palazzo Vecchio, through the Uffizi, above the Ponte Vecchio to the Palazzo Pitti. This enabled the Grand Duke and his family to move easily and safely from their official residence to the Palazzo Pitti. Initially the Palazzo Pitti was used mostly for lodging official guests and for occasional functions of the court, while the Medicis' principal residence remained the Palazzo Vecchio. It was not until the reign of Eleonora's son Francesco I and his wife Johanna of Austria that the palazzo was occupied on a permanent basis and became home to the Medicis' art collection.Land on the Boboli hill at the rear of the palazzo was acquired in order to create a large formal park and gardens, today known as the Boboli Gardens. The landscape architect employed for this was the Medici court artist Niccolò Tribolo, who died the following year; he was quickly succeeded by Bartolommeo Ammanati. The original design of the gardens centred on an amphitheatre, behind the corps de logis of the palazzo. The first play recorded as performed there was Andria by Terence in 1476. It was followed by many classically inspired plays of Florentine playwrights such as Giovan Battista Cini. Performed for the amusement of the cultivated Medici court, they featured elaborate sets designed by the court architect Baldassarre Lanci. 
Question: What is the first name of the Grand Duke whose family was enabled to move easily and safely from their official residence?

Output: Cosimo.


Input: Consider Input: Passage: Feeling unsettled, Etty left Rome for Venice, intending to remain there for 10 days and then return to England. Evans preferred to remain in Rome, so Etty travelled alone, pausing briefly in Florence and in Ferrara (where he stopped to kiss the armchair of Ludovico Ariosto). The painter Charles Lock Eastlake, then resident in Rome, had provided Etty with a letter of introduction to Harry D'Orville, British Vice consul in Venice; D'Orville was so impressed with Etty that he arranged for him to stay in his own house, rather than in lodgings. Etty had long considered Venice his spiritual home and "the hope and idol of my professional life", and had often wondered why, given its artistic importance, so few English travellers visited the city. He was not disappointed. Throughout the remainder of his life, he looked back on his visit to Venice with great fondness, writing shortly before his death that "Venezia, cara Venezia! thy pictured glories haunt my fancy now!"Although Etty had only intended to stay for 10 days, he was so taken with Venice that he remained for over seven months. He fell into a routine of copying paintings in Venetian collections by day, and attending the life class of the Venetian Academy of Fine Arts by night, producing around 50 oil paintings in total as well as numerous pencil sketches. He was extremely impressed with the high quality of the Venetian Academy; the instructors in their turn were extremely impressed with the quality of Etty's work, in particular his flesh tones. He acquired the nickname of "Il Diavolo" owing to the high speed at which he was able to paint, and watching him at work became something of a spectacle in its own right; luminaries including Gioachino Rossini and Ladislaus Pyrker (then Patriarch of Venice) came to watch him paint. So devoted was Etty to his studies in Venice that he exhibited no original work in 1823, writing to his brother that "If one spent all the time in painting originals, one might as well, nay better, be at home". The members of the Venetian Academy were so impressed by Etty that he was elected an Honorary Academician. 
Question: What is the name of the person that acquired the nickname of "Il Diavolo"?


Output: Etty.
