“Evil communications corrupt good manners” (1 Cor. xv. 33). Paul quoted this iambic line form Menander’s “Thais,” “φθείρουσιν ἤθη χρῆσθ᾽ ὁμιλίαι κακαί.”\nThe proverb about Rome is said to have originated with St. Ambrose, who, when he was asked by St. Augustine whether he should fast on Saturday or not when he was at Rome, although he was not accustomed to do so when at home, replied: “When I am at home I do not fast on Saturday; but when I am at Rome I do, and I think you should follow the custom of every city you visit, if you would avoid scandal.” From this reply originated the hexameter: Cum Romæ fueris Romano vive more = When you shall be at Rome, live after the Roman fashion.
