 Few facts are known about his career.In the earliest Vita, which dates from no earlier than the eighth century and is of a character as much legendary as historical, the account of his life is interlaced with that of his brother Julian (Giuliano), a deacon whose name is similar enough to suggest that they may have been the same person, but now we know (thanks to recent archaeological finds in Gozzano's previous parish church, S. Lorenzo) that they both existed.The "Roman Martyrology" commemorates only Julius.
