Cicero, in Catilinam 2.23
“How will they bear the Appenines covered in frosts and snow? Maybe they think that they can tolerate the cold, because they learned to dance naked at dinner parties.”
Quo autem pacto illi Appeninum atque illas pruinas ac nivis perferent? Nisi idcirco se facilius hiemem toleraturos putant, quod nudi in conviviis saltare didicerunt.
