(1724). Its title means Dido Abandoned. It tells the story of Dido, the first queen of Carthage, and her unhappy love for Aeneas. This was Metastasio's first libretto. The first opera to use this libretto was composed by Domenico Sarro. In the next 100 years more than 40 operas by other composers used this libretto.
