Histories

Then Cleisthenes bade them all be silent and spoke to the company at large: “Suitors for my daughter's hand, I thank you one and all; if it were possible I would grant each of you his wish, neither choosing out one to set him above another nor disparaging the rest.

But since I have but one maiden to plan for and so cannot please all of you, to those of you whose suit is rejected I make a gift of a talent of silver to each, for his desire to take a wife from my house and for his sojourn away from his home; and to Megacles son of Alcmeon do I betroth my daughter Agariste, by the laws of the Athenians.” Megacles accepted the betrothal, and Cleisthenes brought the marriage to pass.

Such is the tale of the choice among the suitors; and thus the fame of the Alcmeonidae resounded throughout Greece [22,39] (nation), EuropeHellas. From this marriage was born that Cleisthenes, named after his mother's father from Sikyon [22.725,37.9833] (Perseus)Sicyon, who gave the Athenians their tribes and their democracy;

he and Hippocrates were born to Megacles; Hippocrates was father of another Megacles and another Agariste, called after Agariste who was Cleisthenes' daughter. She was married to Xanthippus son of Ariphron, and when she was pregnant she saw in her sleep a vision in which she thought she gave birth to a lion. In a few days she bore Xanthippus a son, Pericles.
