After Diana had retired the orchestra became silent and the tones of a lyre were heard.
Then entered Orpheus who began his tale with the words, "I bewailed on the spires of the Apennines the untimely death of my Euridice." But, as he explained, his song had changed as his heart had changed, and since Euridice was no more, he wished now to lay his homage at the feet of the most amiable Princess in the world.

Orpheus was interrupted by the entrance of Atalanta and Theseus and a party of hunters, who brought the first part to an end in an animated dance.

This part concluded with a dance by gods of the sea and the Lombardian rivers.

The third part began with the appearance of Orpheus leading Hymen, to whom he sang praises, accompanying himself on the lyre.
