Valeria quoque per varias provincias quindecim mensibus
plebeio cultu pervagata. — Lactantius de M. P. c. 51.
There is some doubt whether we should compute the fifteen months from the moment of her exile, or from that of her escape. The expression of pervagata seems to denote the latter; but in that case we must suppose that the treatise of Lactantius was written after the first civil war between Licinius and Constantine. See Cuper, p. 254.
