It is likely that this ballet drew on Euripides. This was the first of the ballets used as interval entertainment during performances of Alessandri's opera Ezio. The libretto for the opera states that the ballets were 'by Lefevre and Canziani' but gives no further indication. It is thus possible that this ballet was related to Canziani's earlier ballet titled Alceste e Admeto, which had been performed in Turin in 1776 (see Sartori ID 5848). The other interval entertainments used in the same production were La festa di Flora and Il Pigmalione.
