Tyrannius Rufinus
Although initially skeptical of Christianity, he eventually converted. After several years in Rome, he travelled with Bonosus to Gaul and settled in Trier where he seems to have first taken up theological studies, and where, for his friend Tyrannius Rufinus, he copied Hilary of Poitiers' commentary on the "Psalms" and the treatise "De synodis". Next came a stay of at least several months, or possibly years, with Rufinus at Aquileia, where he made many Christian friends.
