A revised version with different singers including the internationally renowned castrato Senesino in the first of many roles he performed in Handel's works was written for a revival on 28 December 1720.
Fully conceived in period style (it took its cue from an original prompt book), T'Hooft's staging was revived and now ranks among the most significant examples of historically informed performance in opera.
Polissena rebukes her husband Tiridate for his dishonourable behaviour and his adulterous pursuit of his sister-in-law but his only response is to tell her to keep quiet ("Segni di crudeltà").
Tigrane again presses his attentions on her, but Polissena rejects him and can only hope that happier times lie ahead ("Dopo l'orride procelle").
Zenobia is at the end of her endurance; Tiridate is waging war and shedding blood all in the attempt to satisfy his lust for her ("Vuol ch’io serva").
Radamisto is grief-stricken by what he assumes to be his wife's death and prays for peace for her soul ("Ombra cara di mia sposa").
In fact, Radamisto is now in the same palace, having been brought to his sister Queen Polissena by Tigrane, who is hoping that the conflict can now be resolved ("La sorte, il Ciel amor").
Inside the palace, Zenobia is still mourning her fate ("Che farà quest'alma mia") while Tiridate continues to harass her with his desires.
In a room of the palace, Zenobia is concerned that her husband's disguise will be seen through and he seeks to allay her fears ("Dolce bene di quest'alma").
He releases Zenobia and Radamisto, who celebrate their reunion ("Non ho più affanni"), asks forgiveness from his wife, and vows to rule for the benefit of his people for the rest of his life.
A tremendous success, Rinaldo created a craze in London for Italian opera seria, a form focused overwhelmingly on solo arias for the star virtuoso singers.
"[11] In the opinion of 18th century musicologist Charles Burney Radamisto was "more solid, ingenious, and full of fire than any drama which Handel had yet produced in this country.
"[12] The opera is scored for strings, flute, two oboes, bassoon, two horns and continuo instruments (cello, lute, harpsichord).
To Jonathan Keates, Radamisto is a work of the first stage of Handel's maturity as a composer, with its "masterly" invention and characterisation through music.
