Alexander entered readily into this scheme, and various courtiers, Ptolemy among the rest, undertook to aid him in the accomplishment of it. The embassy was sent. The governor of Caria was very much pleased with the change which they proposed to him. 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.
