79. Three of the provinces, Zabdicene, Arzanene, and
Carduene, are allowed on all sides. But instead of the other
two, Peter (in Excerpt Leg. p. 30) inserts Rehimene and
Sophene. I have preferred Ammianus (l. xxv. 7), because it
might be proved that Sophene was never in the hands of the
Persians, either before the reign of Diocletian or after
that of Jovian. For want of correct maps, like those of M.
d'.Anville, almost all the moderns, with Tillemont and
Valesius at their head, have imagined that it was in respect
to Persia, and not to Rome, that the five provinces were
situate beyond the Tigris.
