The Roman History · Amm. 18.2.2

He had sent Hariobaudes, a tribune who at that time had no particular command, a man of honour, loyalty, and courage, under pretext of an embassy, to Hortarius the king who was now in a state of friendship with us; in order that from his court Hariobaudes might easily proceed to the frontiers of the enemy whom he was proposing to attack; and so ascertain what they were about, being thoroughly skilled in the language of the barbarians.
