But while this thing was rather a matter of suspicion than of certainty, Antigonus accidentally met Xychus, whom he seized and brought to the palace;
then leaving him in custody of guards, Antigonus went on to the apartment of Philip, to whom he said, “I think I understood from many conversations, that you would value it highly, if you could ascertain the whole truth respecting your sons, which of the two was assailed by the other's deceit and secret machinations.
Xychus, the only man in the world who can unravel this mystery, is now in your power. I met him by accident, and I have brought him to the palace; order him to be called into your presence.”
On being brought in, he at. first denied; but with such irresolution, as showed that by a slight application to his fears he would become a ready informer.
He did not withstand the sight of the executioner [p. 1911]
and the instruments of torture, but disclosed the whole process of the villany of the ambassadors, and his own services therein.
Persons were instantly despatched to seize the ambassadors, and they apprehended by surprise Philocles, who was present, but Apelles, who had been sent in pursuit of a person called Chaerea, having heard of the information given by Xychus, went over into Italy.
With respect to Philocles, no certain account has been published: some say, that for a time he boldly denied all knowledge of the matter; but that when Xychus was confronted with him, he persisted no longer; others, that he even suffered the rack without confessing.
Philip's grief was renewed and doubled; and he felt his unhappiness, with regard to his children, press the heavier on him, because one of them was not.
