Although Antipater, on his return to Macedon, came back loaded with honors, and in the full and triumphant possession of power, his situation was still not without its difficulties. He had for enemies, in Macedon, two of the most violent and unmanageable women that ever lived--Olympias and Eurydice--who quarreled with him incessantly, and who hated each other even more than they hated him. Olympias was at this time in Epirus. She remained there, because she did not choose to put herself under Antipater's power by residing in Macedon. She succeeded, however, by her maneuvers and intrigues, in giving Antipater a great deal of trouble. Her ancient animosity against him had been very much increased and aggravated by the failure of her plan for marrying her daughter Cleopatra to Perdiccas, through the advances which Antipater made in behalf of his daughter Nicæa; and though Nicæa and Perdiccas were now dead, yet the transaction was an offense which such a woman as Olympias never could forgive.
