In fact, the whole plan seemed to be going on very successfully toward its accomplishment, when, by some means or other, Philip discovered the intrigue.

He went immediately into Alexander's apartment, highly excited with resentment and anger.

He had never intended to make Aridaeus, whose birth on the mother's side was obscure and ignoble, the heir to his throne, and he reproached Alexander in the bitterest terms for being of so debased and degenerate a spirit as to desire to marry the daughter of a Persian governor; a man who was, in fact, the mere slave, as he said, of a barbarian king.
Alexander's scheme was thus totally defeated; and so displeased was his father with the officers who had undertaken to aid him in the execution of it, that he banished them all from the kingdom.

Ptolemy, in consequence of this decree, wandered about an exile from his country for some years, until at length the death of Philip enabled Alexander to recall him.

Alexander succeeded his father as King of Macedon, and immediately made Ptolemy one of his principal generals.
