Task: Question Answering
Input (English): Passage: Despite the positive reception accorded to L'Arianna at its premiere, the duke did not request a second showing, as he had with L'Orfeo the previous year". The next hint of a performance of L'Arianna is in 1614, when the Medici court in Florence requested a copy of the score, presumably with the intention of staging it. There is, however, no record of any such performance there. Early in 1620 Striggio asked Monteverdi to send him the music for a projected performance in Mantua as part of the celebration for the Duchess Caterina's birthday. Monteverdi went to the trouble and expense of preparing a new manuscript with revisions; had he had more time, he informed Striggio, he would have revised the work more thoroughly. Hearing nothing further from the Mantuan court, Monteverdi wrote to Striggio on 18 April 1620, offering to help with the staging. A month or so later, however, he learned that the duchess's celebrations had been scaled back, and that there had been no performance of L'Arianna.There is some evidence to suggest a possible performance in Dubrovnik, in or some time after 1620; a Croatian translation of the libretto was published in Ancona in 1633. However, the only known revival of the work came in Venice, in 1640. Public theatre opera had come to the city in March 1637, when the new Teatro San Cassiano opened with a performance of L'Andromeda by Francesco Manelli. The popularity of this and other works led to more theatres converting their facilities for opera; L'Arianna was chosen to inaugurate the Teatro San Moisè as an opera house during the 1639–40 Carnival (the precise date of this performance is not recorded). A revised version of the libretto had been published in 1639, with substantial cuts and revisions from the 1608 version to remove passages too specifically linked to the Mantuan wedding. The composer, who was by then 73 years old, had acquired considerable prestige in Venice, having been director of music at St Mark's Basilica since 1613. The dedication in the revised and republished libretto describes him as "[the] most celebrated Apollo of the century and the highest intelligence of the heavens of humanity".  The opera was received with great enthusiasm by a Venetian audience already familiar with the lament, which had been published in the city in 1623. Within a few weeks the theatre replaced L'Arianna with Monteverdi's new opera Il ritorno d'Ulisse in patria, which proved an even greater success. 
Question: What is the name of the 73 year old composer who had acquired considerable prestige in Venice?
Output (English): Monteverdi.
