 As Plutarch describes, the night before the consummation of their marriage, Olympias dreamed that a thunderbolt fell upon her womb and a great fire was kindled, its flames dispersed all about and then were extinguished.After the marriage Philip dreamed that he put a seal upon his wife's womb, the device of which was the figure of a lion.Aristander's interpretation was that Olympias was pregnant of a son whose nature would be bold and lion-like.
