As for the lineage of Alexander, on his father's side he was a descendant of Heracles through Caranus
, and on his mother's side a descendant of Aeacus through Neoptolemus; this is accepted without any question. And we are told that Philip, after being initiated into the mysteries of Samothrace at the same time with Olympias, he himself being still a youth and she an orphan child, fell in love with her and betrothed himself to her at once with the consent of her brother, Arymbas.
Well, then, the night before that on which the marriage was consummated, the bride dreamed that there was a peal of thunder and that a thunder-bolt fell upon her womb, and that thereby much fire was kindled, which broke into flames that travelled all about, and then was extinguished. At a later time, too, after the marriage, Philip dreamed that he was putting a seal upon his wife's womb; and the device of the seal, as he thought, was the figure of a lion.
The other seers, now, were led by the vision to suspect that Philip needed to put a closer watch upon his marriage relations; but Aristander of Telmessus said that the woman was pregnant, since no seal was put upon what was empty, and pregnant of a son whose nature would be bold and lion-like.
Moreover, a serpent was once seen lying stretched out by the side of Olympias as she slept, and we are told that this, more than anything else, dulled the ardour of Philip's attentions to his wife, so that he no longer came often to sleep by her side, either because he feared that some spells and enchantments might be practised upon him by her, or because he shrank from her embraces in the conviction that she was the partner of a superior being.
But concerning these matters there is another story to this effect: all the women of these parts were addicted to the Orphic rites and the orgies of Dionysus from very ancient times (being called Klodones and Mimallones
), and imitated in many ways the practices of the Edonian women and the Thracian women about Mount Haemus, from whom, as it would seem, the word ‘threskeuein’
came to be applied to the celebration of extravagant and superstitious ceremonies.
Now Olympias, who affected these divine possessions more zealously than other women, and carried out these divine inspirations in wilder fashion, used to provide the revelling companies with great tame serpents, which would often lift their heads from out the ivy and the mystic winnowing-baskets,
or coil themselves about the wands and garlands of the women, thus terrifying the men.
