Hercules (HWV 60) was first performed on 5 January 1745 at King’s Theatre, Haymarket, London. Categorized as a drama, it traditionally has been performed in the oratorio style (i.e., a concert performance). Following its performance as an opera at the Brooklyn Academy of Music, this production by William Christie now appears at the Barbican in London. “This extraordinary opera recounts the tragic tale of a hero literally poisoned by the jealousy of his misguided wife. In this modern-dress production, punctuated by Greek references, the action takes place on a sand-covered, amphitheatre-style arena where the chorus is used as Handel originally intended, to embody the people of Trachis and comment on the action.” Here are five reviews.
