The program broadcasts the best performances of famous operas, ballets, musicals, and operettas, presenting their plots and the history of their creation.
Before each act, the corresponding part of libretto is read, which makes the listening experience more vivid and comprehensible.
The opera's libretto was written by Ranieri de' Calzabigi on the basis of a variant of the ancient Greek legend incorporated in Virgil's "Georgics." The antique personages are presented in a lofty and touching simplicity in the opera and express real feelings peculiar to ordinary humans. The end of the opera, unlike that of the legend, is happy.
