La catena d'Adone (The Chain of Adonis) is the only surviving opera by the Italian composer Domenico Mazzocchi.
The libretto, in a prologue and five acts, is by Ottavio Tronsarelli and is based on episodes from Giambattista Marino's epic poem Adone (1623).
The demarcation between recitative and aria grew more distinct in this work as Mazzocchi tried to escape what he called the "monotony" of Florentine opera.
In the prologue, Apollo descends from the clouds and laments Venere's desertion of her husband, the god Vulcan, for the young Adone.
In the opera proper (drawn from Cantos XII and XIII of Marino's poem), Adone has to flee from Venere's former lover, the god Marte, and takes refuge in the land of the enchantress Falsirena, who falls in love with him.
