The theme of the journey has a primary relevance in the first book of Sidonius Apollinaris’ Letters. It represents not only an opportunity of personal growth, but also a way to rediscover the paths that lead to the very bases of Romanitas. In this sense, the peregrinatio shapes the life of travellers: on the way to Rome Sidonius Apollinaris, born in Lyon, really becomes Roman (Sidon. Epist. 1.5); Eutropius, who decides to remain in Gaul, refuses his cultural identity, turning into a peregrinus in his own land (Sidon. Epist. 1.6).
