Same musicTitle already names the work
'Seuls confidents de mes...' matches, with the same words and transposed, an excerpt from Iphigénie en Tauride attributed to Campra; the title already names the work, with a query. The opera was begun by Desmarest and completed by Campra, who wrote the scenes between Oreste and Iphigénie in Acts IV and V; this air follows their Act V duet (CMBV edition and 2024 recording booklet).
