It is not known when Monteverdi received the libretto from Badoaro, but this was presumably during or before 1639 since the work was being prepared for performance in the 1639–40 carnival.
Det er ikke kendt, hvornår Monteverdi modtog librettoen fra Badoaro, men det skete formentlig i 1639 eller før, da værket skulle opføres under karnevallet i 1639-1640.
