The story behind it
Word for word the line says “If you live at Rome, live in the Roman manner.” It is a rhymed-style couplet opener from medieval Latin, a proverb rather than a line from a classical author.
The thought is usually traced to Saint Ambrose, bishop of Milan in the 4th century. Asked whether to fast on Saturdays as in Rome or not as in Milan, he reportedly advised following the custom of the local church, and later writers condensed that advice into verse.
The saying lives on in English as “When in Rome, do as the Romans do”. It is still the standard advice for travellers, expats and new arrivals: respect local ways and fit in.
How to use “Si vivis Romae, Romano vivito more”
It suits a travel journal, a card for someone moving abroad, a language-school sign, or a light-hearted caption on a trip to Italy. It also works as a gentle motto about being a good guest anywhere.

Common mistakes
- It is a medieval proverb, not a line from Cicero, Virgil or another classical author, so do not credit it to one.
- Romae means “in Rome”. Adding the preposition in before it is wrong.
- Vivito is a singular command. To address several people you would need the plural vivitote.
- Changing Romano more to another place, such as Atheniensi more, is possible, but the adjective must agree with mos, which is masculine.
