Ithome
A nymph from whom the Messenian hill of Ithome derived its name. According to a Messenian tradition, Ithome and Neda, from whom a small river of the country derived its name, were said to have nursed Zeus, and to have bathed the infant god in the well Clepsydra. (Description of Greece by Pausanias)
From Lives of the Noble Grecians and Romans By Plutarch. Aratus
From Smith's Dictionary of Greek and Roman Biography and MythologyPhilip having committed this wickedness, and doing his best to set the Messenians by the ears together more than before, Aratus arrived there, and both showed plainly that he took it ill himself, and also he suffered his son bitterly to reproach and revile him. It should seem that the young man had an attachment for Philip, and so at this time one of his expressions to him was, that he no longer appeared to him the handsomest, but the most deformed of all men, after so foul an action. To all which Philip gave him no answer, though he seemed so angry as to make it expected he would, and though several times he cried out aloud, while the young man was speaking. But as for the elder Aratus, seeming to take all that he said in good part, and as if he were by nature a politic character and had a good command of himself, he gave him his hand and led him out of the theater, and carried him with him to the Ithomatas, to sacrifice there to Jupiter, and take a view of the place, for it is a post as fortifiable as the Acro-Corinthus, and, with a garrison in it, quite as strong and as impregnable to the attacks of all around it.
