“La grotto di Trofonio” is an opera buffa by Giovanni Paisiello, staged to celebrate the bicentenary of his death. First performed in 1785, this opera enjoyed a resounding and long-lasting success. The cavern of the philosopher-sorcerer Trofonio was well-known in ancient Greece; those who were granted to question the oracle were given two types of water to drink: one made one forget all one’s worries, the other made one remember what he had seen in the cavern. In the libretto of this opera, those who enter the cavern are transformed in their character; this artifice throws the lives of two young sisters into confusion, when their lovers accidentally enter the cavern and come out radically changed. The version here proposed is interpreted by a cast of specialists of this repertoire, which includes Domenico Colaianni, Daniela Mazzucato and Giorgio Caoduro.
