Finally, following an unprecedented and destructive course, Gallus also ventured to commit the atrocious crime which, to his utter disgrace, Gallienus is said to have once hazarded at Rome. Taking with him a few attendants with concealed weapons, he used to roam at evening about the inns and street-corners, inquiring of every one in Greek, of which he had remarkable command, what he thought of the Caesar.
