Zenobia, regina de’ Palmireni (Zenobia, Queen of the Palmyrans) is an opera in three acts by Tomaso Albinoni with a libretto by Antonio Marchi. It was Albinoni’s first opera, written when he was only 23, and was first performed at the 1694 carnival at the Teatro Santi Giovanni e Paolo in Venice. The work was popular and performances continued for several weeks. Albinoni was also the first composer to write an opera on the theme of Zenobia.
