This article takes as its subject the remarkable diary kept by a young English gentleman named John North from 1575 to 1579. On his journey home from Italy in 1575 -77, North changed the language of his diary from English to Italian. On his return to London, he continued to keep a record of his everyday life in Italian. This article uses North's diary as a starting point from which to reconstruct the social and sensory worlds of a returned traveler and Italianate gentleman. In doing so, it offers a way of bridging the gap between individual experiences and personal networks on the one hand, and the wider processes of cultural encounter and linguistic contact on the other.
