Jean-Baptiste Lully’s unrivalled position at the Sun King’s court gave him freedom to produce numerous grand theatre works. Acis et Galatée is acknowledged as one of his masterpieces with its adroit alternation of effects and situations and its substantial use of dances and choruses. The opera was composed as part of lavish celebrations for the Dauphin’s stay at the castle of Anet and is a pastorale héroïque, with its plot based on the love story between the nymph Galatée and the shepherd Acis. The work’s ‘heroic’ element is provided by the presence of the mythical Neptune and cyclops Polyphème who, for the love of Galatée, crushes Acis under a boulder.
