Thespis, or The Gods Grown Old, is an operatic extravaganza that was the first collaboration between dramatist W. S. Gilbert and composer Arthur Sullivan. No musical score of Thespis was ever published, and most of the music has been lost. Gilbert and Sullivan went on to become the most famous and successful artistic partnership in Victorian England, creating a string of enduring comic opera hits, including H.M.S. Pinafore, The Pirates of Penzance and The Mikado. Thespis premièred in London at the Gaiety Theatre on 26 December 1871. Like many productions at that theatre, it was written in a broad, burlesque style, considerably different from Gilbert and Sullivan's later works. It was a success, for a Christmas entertainment of the time, and closed on 8 March 1872, after a run of 63 performances. It was advertised as "An entirely original Grotesque Opera in Two Acts". The story follows an acting troupe headed by Thespis, the legendary Greek father of the drama, who temporarily trade places with the gods on Mount Olympus, who have grown elderly and ignored. The actors turn out to be comically inept rulers. Having seen the ensuing mayhem down below, the angry gods return, sending the actors back to Earth as "eminent tragedians, whom no one ever goes to see". Gilbert would return to this theme twenty-five years later in his last opera with Sullivan, The Grand Duke, in which a theatre company temporarily replaces the ruler of a small country and decides to "revive the classic memories of Athens at its best". Seasonal works like Thespis were not normally expected to endure, and apart from a benefit performance shortly after the original staging, Thespis was not performed again during its creators' lifetimes. A renewed interest in the piece began in the 1950s, and numerous productions have been performed since, either with music taken from Sullivan's other works, or with original music. Synopsis Act I Scene: A Ruined Temple on the Summit of Mount Olympus On Mount Olympus, the elderly deities complain of feeling old and lament their waning influence on Earth. Mercury complains that the older gods are lazy and leave all their duties to him, while he gets no credit for all his drudgery. Jupiter says that matters have reached a crisis, but he is unsure what can be done about it. Just then, the gods see a swarm of mortals ascending the mountain and withdraw
