Pancirolus, in his elaborate Commentary assigns to the Notitia a date almost similar to that of the Theodosian Code; but his proofs, or rather conjectures, are extremely feeble. I should be rather inclined to place this useful work between the final division of the empire (A.D. 395) and the successful invasion of Gaul by the barbarians (A.D. 407). See Histoire des Anciens Peuples de l'Europe, tom. vii. p. 40.
