The opera requires a cast of six, and the original performers are shown next to the roles:
Giulia Soprano Marianna Benti Bulgarelli, 'La Romanina'
Alessandro Soprano Francesco di Grandi (castrato)
Sallustia Soprano Faustina Bordoni
Albina Contralto Diana Vico
Claudio Soprano Antonio Pasi (castrato)
Marziano Tenor Francesco Guicciardi
The instrumentation is 2 violins (with oboe doubling), viola, bass
and keyboard continuo. The opera contains two male soprano roles
originally sung by castrati (Alessandro, Claudio), two female soprano
roles (Giulia, Sallustia), a contralto role (Albina), and one tenor
part (Marziano). The castrato roles are perhaps uncomfortably high for
most countertenors : one performance suggestion is for all the roles
to be played by women. (The tenor part either at pitch, or
controversially up an octave.)
The libretto was written by the leading Venetian playwright, Apostolo Zeno. All the libretti for Lotti's operas were newly commissioned texts, and most would be re-used by other composers. Zeno's libretto for Alessandro Severo was set to new music a further 15 times, including by Handel.
A FULL SCORE of the complete opera is available to download as a PDF. Instrumental parts are available on request.
