The date of the first performance of "L'incoronazione" and the number of times the work was performed are unknown; the only date recorded is that of the beginning of the carnival, 26 December 1642. A surviving scenario, or synopsis, prepared for the first performances, gives neither the date nor the composer's name. The identity of only one of the première cast is known for certain: Anna Renzi, who played Ottavia. Renzi, in her early twenties, is described by Ringer as "opera's first prima donna" and was, according to a contemporary source, "as skillful in acting as she excellent in music". On the basis of the casting of the opera which shared the theatre with "L'incoronazione" during the 1642–43 season, it is possible that Poppea was played by Anna di Valerio, and Nerone by the castrato Stefano Costa. There are no surviving accounts of the opera's public reception, unless the encomium to the singer playing Poppea, part of the libretto documentation discovered at Udine in 1997, relates to the first performance.
