The revival of the spring of 1734, in which Giovanni Carestini took the role of Mirtillo, was far more successful, but Handel significantly altered the music: only seven of the original arias remained, and those cut were replaced by arias from Handel's cantatas or earlier operas. This production proved popular and enjoyed a run of 13 performances. In the winter of 1734 "Il pastor fido" was revived again: Carestini remained as Mirtillo and the English tenor John Beard took the role of Silvio. A newly composed prologue, "Terpsicore", was added to the opera for this run of performances. The prologue consisted of solo arias, choral movements, and orchestral writing for dance: the danced role of Terpsichore was performed by Marie Sallé, whose dance company had been engaged by Covent Garden manager John Rich.
