The sources of the tale, O ye grave Signori Tedeschi?
The sources are partly to be traced to a neat little French vaudeville, very sparkling--Camille, or the Husband Asserted; and again to a certain Chronicle that may be mediaeval, may be modern, and is just, as the great Shakespeare would say, 'as you like it.'" Agostino recited some mock verses, burlesquing the ordinary libretti, and provoked loud laughter from Carlo Ammiani, who was familiar enough with the run of their nonsense.
"Camilla is the bride of Camillo.

I give to her all the brains, which is a modern idea, quite! He does all the mischief, which is possibly mediaeval.

They have both an enemy, which is mediaeval and modern.

None of them know exactly what they are about; so there you have the modern, the mediaeval, and the antique, all in one.

Finally, my friends, Camilla is something for you to digest at leisure.
