When in Rome, do as the Romans do
Meaning
One should adapt to the customs and practices of the place they are visiting or residing in.
Origin
Imagine the late 4th century, with the Roman Empire still shaping much of the known world. The esteemed theologian St. Augustine faced a dilemma during his visit to Rome: the local church fasted on Saturdays, a custom contrary to his home in Milan. Seeking clarity, he reached out to the venerable St. Ambrose, the Bishop of Milan, whose response was both practical and profound. Ambrose declared, "When I am here [in Milan], I do not fast on Saturday; when I am in Rome, I fast on Saturday." This simple yet powerful advice, urging adaptation to local customs and traditions, was meticulously preserved in a letter by Augustine's correspondent, Januarius. It quickly transcended its religious context, becoming a universal truth about fitting in wherever one finds oneself.
Examples
- I know you usually eat dinner late, but we're in Spain now, so when in Rome, do as the Romans do and enjoy the siesta before a late meal.
- Even though he found the local customs a bit strange at first, he reminded himself, when in Rome, do as the Romans do, and embraced the experience.
