The libretto of ‘Orfeo’ was by Calzabigi, a prominent man of letters, but it seems probable that Gluck’s own share in it was not a small one. The careful study which he had given to the proper conditions of opera was not likely to exclude so important a question as that of the construction and diction of the libretto, and the poem of ‘Orfeo’ shows so marked an inclination to break away from the conventionality and sham sentiment of the time that we can confidently attribute much of its originality to the influence of the composer himself.

Time after time his pathetic song is broken by a sternly decisive ‘No,’ but in the end he triumphs, and the Furies grant him passage. The next scene is in the Elysian fields. After an introduction of charming grace, the spirits
