"Aithra the daughter of Pittheus and large-eyed Klymene."

Others reject this verse, and the legend about Mounychus, who is said to
have been the bastard son of Laodike, by Demophoon, and to have been
brought up in Troy by Aithra. But Istrus, in his thirteenth book of his
'History of Attica,' tells quite a different and peculiar story about
Aithra, that he had heard that Paris was conquered by Achilles and
Patroklus near the river Spercheius, in Thessaly, and that Hector took
the city of Troezen by storm, and amongst the plunder carried off
Aithra, who had been left there. But this seems impossible.

XXXV. Now Aidoneus the Molossian king chanced to be entertaining
Herakles, and related to him the story of Theseus and Peirithous, what
they had intended to do, and how they had been caught in the act and
punished. Herakles was much grieved at hearing how one had perished
ingloriously, and the other was like to perish. He thought that nothing
would be gained by reproaching the king for his conduct to Peirithous,
but he begged for the life of Theseus, and pointed out that the release
of his friend was a favour which he deserved. Aidoneus agreed, and
Theseus, when set free, returned to Athens, where he found that his
party was not yet overpowered. Whatever consecrated grounds had been set
apart for him by the city, he dedicated to Herakles, and called Heraklea
instead of Thesea, except four, according to Philochorus. But, as he at
once wished to preside and manage the state as before, he was met by
factious opposition, for he found that those who had been his enemies
before, had now learned not to fear him, while the common people had
become corrupted, and now required to be specially flattered instead of
doing their duty in silence.
