 The title of "pecuarius" (or sometimes "pequarius") is also associated with the veterinary service, though the exact distinction between the duties of a "veterinarius" and a "pecuarius" are uncertain.Paternus does not mention the title in his list of "immunes" which, unless he is grouping all animal workers together under the term "veterinarii", they were of lower importance.It can be speculated that the "veterinarius" was concerned with the medical care of the animals while the "pecuarius" served in more hand-on roles as assistants.
