Arianna in Nasso is a 1733 opera by Nicola Porpora to a libretto by Paolo Rolli, chief conductor of the Opera of the Nobility.
The choice of the subject of Ariadne was a challenge to Handel, whose Arianna in Creta was completed by 5 October 1733.
[1] Handel's Arianna in Creta was based on Pietro Pariati's much-set Arianna e Teseo, in the later of two versions by Leonardo Leo (1729).
This was a libretto which Porpora himself had also used for his own Arianna e Teseo (1721).
[2] Handel's choice of libretto obliged Porpora to turn to Rolli's libretto which was modeled not on Pariati but on Stampa's libretto to Giovanni Porta's dramma pastorale, Arianna.
