While Philip had arranged everything for his descent upon Persia, and had been frequently absent from home, his domestic affairs in his own capital, which had never been of a very satisfactory character, took such an unfavorable turn as to require his personal attention. As a husband, Philip had often given just cause of complaint to Olympias, his royal spouse. Wherever he went he formed liaisons, and several illegitimate children were openly recognized by him as his own. But when Olympias, the Queen, laid herself open to a suspicion of having violated her marriage vows in his absence, he repudiated her, charging her with gross infidelity, and intimating that he had very strong doubts of being the father of Alexander. Olympias thereupon went back to her native state, Epirus, accompanied by Alexander, who was highly incensed at the treatment shown to his mother and himself.
Philip contracted a second marriage with Cleopatra, a niece of Attalus, one of his generals; and it is said that at the wedding feast Attalus, half intoxicated, expressed the wish and hope that Cleopatra might give the Macedonians a lawful heir to the kingdom. This remark, overheard by Alexander, so enraged him that, throwing a full cup at Attalus’s head, he shouted to him: “What, you scoundrel! am I then a bastard?” Whereupon Philip, taking Attalus’s part, rose from his seat, and rushing with his drawn sword upon Alexander would have run his son through, if he had not, being himself more than half drunk with wine, slipped and fallen on the floor; at which sight Alexander scornfully said: “See there the man who is making great preparations to invade Asia at the head of a powerful army, and who falls to the ground like a helpless child in going from one seat to another.”
It is said that after this debauch both Olympias and Alexander retired from Philip’s capital, the one going to Epirus, and the other to Illyria. By the counsels and efforts of Demaratus, the Corinthian, an old friend of the royal family, Philip was, however, induced to send for Alexander, and the son returned to his father’s court. Soon afterwards, Cleopatra gave birth to a son; and the fears of Alexander, who remained in communication with his mother and was filled with jealous rage by her, revived.
