Aureliano in Palmira is an operatic dramma serio in two acts written by Gioachino Rossini to an Italian libretto in which the librettist was credited only by the initials "G. F. R." The libretto has generally been attributed to Felice Romani, but sometimes to the otherwise unknown Gian Francesco Romanelli. It has been suggested that the latter name may have resulted from a confusion of Romani with Luigi Romanelli, La Scala's house poet prior to Romani's appointment to the post.

The Barber of Seville, or The Useless Precaution is an opera buffa in two acts composed by Gioachino Rossini with an Italian libretto by Cesare Sterbini. The libretto was based on Pierre Beaumarchais's French comedy The Barber of Seville (1775). The première of Rossini's opera took place on 20 February 1816 at the Teatro Argentina, Rome, with designs by Angelo Toselli.
