Notwithstanding, however, the extraordinary discretion and wisdom which characterized the mind of Alexander in his early years, he was often haughty and headstrong, and in cases where his pride or his resentment were aroused, he was sometimes found very impetuous and uncontrollable. His mother Olympias was of a haughty and imperious temper, and she quarreled with her husband, King Philip; or, perhaps, it ought rather to be said that he quarreled with her. Each is said to have been unfaithful to the other, and, after a bitter contention, Philip repudiated his wife and married another lady. Among the festivities held on the occasion of this marriage, there was a great banquet, at which Alexander was present, and an incident occurred which strikingly illustrates the impetuosity of his character.
