Note
1. The original text is dual column, with English on the left and Italian on the right, with musical scores interspersed throughout. In this version, the complete English text for a scene is shown first, followed by the complete Italian text for the scene. The musical scores are placed as near as possible to the original version.
2. The page numbering is, of necessity, quite different from the original text. Each scene and score simply has its own page number.
