Zenobia, wife of Rhadamistus, is the prisoner of Pharasmanes, the king of Iberia. When Phenice, her companion, attempts to persuade Zenobia that she should accept the love Pharasmanes offers her in the hope that she will become his queen, Zenobia, who has been using the name Ismenia, reveals that she cannot accept Pharasmanes because the king is her uncle and the father of Rhadamistus. Zenobia explains that her father, Mithridates, reared Rhadamistus as if the boy were his own son, but when Pharasmanes invaded the Armenian kingdom of Mithridates, Mithridates turned against Rhadamistus and refused to allow him to marry Zenobia as Rhadamistus had expected.

Pharasmanes appears and criticizes Arsames for returning to Iberia without permission. When Arsames declares that he has come in support of his father, to meet the invasion planned by Corbulo on behalf of Rome and Syria, Pharasmanes dismisses the excuse and forbids his son to profess love for Ismenia or ever to see her again.
