Nau monologue (Act 3) — Amphitryon

What do you wish us to decide, when two Amphitryons are before us and all the warmth of our friendship is in suspense? If we were now to show towards you, we fear we might make a mistake, and not recognise you. Truly we see in you the appearance of Amphitryon, the glorious support of the Thebans' well-being; but we also see the same appearance in him, and we cannot judge which he is. Our duty is not doubtful, the impostor ought to bite the dust at our hands; but this perfect resemblance hides him between you two; and it is too hazardous a stroke to undertake in the dark. Let us find out quietly on which side the imposture may be; then, as soon as we have unravelled the adventure, it will not be necessary for you to tell us our duty.
