Note: There is no reason to believe that any of the following productions cited in earlier musicological literature ever took place: ''Medea'' (Parma, 1764); ''Erifile'' (Munich, 1773); ''Achille in Sciro'' (Naples, 1775); and ''Merope'' (Naples, 1775). Furthermore, there is no reason to believe that Mysliveček contributed any music to a production of ''Armida'' that took place in Lucca in 1778.〔Documentation of how all of these spurious productions entered the musicological literature is found in Catalog II of Freeman, ''Josef Mysliveček''.〕 The cantata ''Il Parnaso confuso'' is sometimes referred to in error as Mysliveček's first opera. Reports that it was performed in Parma in 1765 are conjectural; there is no documentation to verify its true date of composition or the venue of its first performance.
