I have mentioned that the serpent was often exhibited by request; he was not completely visible, but the tail and body were exposed, while the head was concealed under the prophet's dress. By way of impressing the people still more, he announced that he would induce the God to speak, and give his responses without an intermediary. His simple device to this end was a tube of cranes' windpipes, which he passed, with due regard to its matching, through the artificial head, and, having an assistant speaking into the end outside, whose voice issued through the linen Asclepius, thus answered questions. These oracles were called _autophones_, and were not vouchsafed casually to any one, but reserved for officials, the rich, and the lavish. It was an autophone which was given to Severian regarding the invasion of Armenia. He encouraged him with these lines: Armenia, Parthia, cowed by thy fierce spear, To Rome, and Tiber's shining waves, thou com'st, Thy brow with leaves and radiant gold encircled. Then when the foolish Gaul took his advice and invaded, to the total destruction of himself and his army by Othryades, the adviser expunged that oracle from his archives and substituted the following: Vex not th' Armenian land; it shall not thrive; One in soft raiment clad shall from his bow Launch death, and cut thee off from life and light. For it was one of his happy thoughts to issue prophecies after the event as antidotes to those premature utterances which had not gone right. Frequently he promised recovery to a sick man before his death, and after it was at no loss for second thoughts: No longer seek to arrest thy fell disease; Thy fate is manifest, inevitable. Knowing the fame of Clarus, Didymus, and Mallus for sooth-saying much like his own, he struck up an alliance with them, sending on many of his clients to those places. So Hie thee to Clarus now, and hear my sire. And again, Draw near to Branchidae and counsel take. Or Seek Mallus; be Amphilochus thy counsellor.
