But the disorders of his family, chiefly caused by his new marriages and attachments (the troubles that began in the women's chambers spreading, so to say, to the whole kingdom), raised various complaints and differences between them, which the violence of Olympias, a woman of a jealous and implacable temper, made wider, by exasperating Alexander against his father. Among the rest, this accident contributed most to their falling out. At the wedding of Cleopatra, whom Philip fell in love with and married, she being much too young for him, her uncle Attalus in his drink desired the Macedonians would implore the gods to give them a lawful successor to the kingdom by his niece. This so irritated Alexander, that throwing one of the cups at his head, "You villain," said he, "what, am I then a bastard?" Then Philip, taking Attalus's part, rose up and would have run his son through; but by good fortune for them both, either his over-hasty rage, or the wine he had drunk, made his foot slip, so that he fell down on the floor. At which Alexander reproachfully insulted over him: "See there," said he, "the man who makes preparations to pass out of Europe into Asia, overturned in passing from one seat to another." After this debauch, he and his mother Olympias withdrew from Philip's company, and when he had placed her in Epirus, he himself retired into Illyria.
About this time, Demaratus the Corinthian, an old friend of the family, who had the freedom to say anything among them without offence, coming to visit Philip, after the first compliments and embraces were over, Philip asked him whether the Grecians were at amity with one another. "It ill becomes you," replied Demaratus, "to be so solicitous about Greece, when you have involved your own house in so many dissensions and calamities." He was so convinced by this seasonable reproach, that he immediately sent for his son home, and by Demaratus's mediation prevailed with him to return.
Not long after this, Pausanias, having had an outrage done to him at the instance of Attalus and Cleopatra, when he found he could get no reparation for his disgrace at Philip's hands, watched his opportunity and murdered him. The guilt of which fact was laid for the most part upon Olympias, who was said to have encouraged and exasperated the enraged youth to revenge; and some sort of suspicion attached even to Alexander himself, who, it was said, when Pausanias came and complained to him of the injury he had received, repeated the verse out of Euripides's Medea-
"On husband, and on father, and on bride." However, he took care to find out and punish the accomplices of the conspiracy severely, and was very angry with Olympias for treating Cleopatra inhumanly in his absence.
