et meus pater nunc intus hic cum illa cubat,
et haec ob eam rem nox est facta longior,
dum cum illa quacum volt voluptatem capit;
sed ita adsimulavit se, quasi Amphitruo siet.

And my father is there inside this very moment with her in
his arms, and it is on this account that the present night
has been prolonged while he enjoys the society of his
heart’s delight. All this in the guise of Amphitryon, you
understand.

Nunc ne hunc ornatum vos meum admiremini,
quod ego huc processi sic cum servili schema:
veterem atque antiquam rem novam ad vos proferam,
propterea ornatus in novom incessi modum.

Now don’t be surprised at this get-up of mine and because I
appear here in the character of a slave as I do: I am going
to submit to you a new version of a worn and ancient tale,
hence my appearance in a new get-up.

nam meus pater intus nunc est eccum Iuppiter; 120
in Amphitruonis vertit sese imaginem
omnesque eum esse censent servi qui vident:
ita versipellem se facit quando lubet.

The point is, my father Jupiter is now inside there, mark
you. He has turned himself into the very image of Amphitryon,
and all the servants that see him believe that’s who he is.
See how he can change his skin when he likes!
