Agariste of Sicyon in Wikipedia
Agariste (Ancient Greek: Ἀγαρίστη) (fl. 6th century BC, around 560 BC) was the daughter, and possibly the heiress, of the tyrant of Sicyon, Cleisthenes. Her father wanted to marry her to the best of the Hellenes and, subsequently, he organized a competition, whose prize was his own daughter. According to his declaration, all the eligible young men had to appear in Sicyon within 60 days. Finally, twelve competitors appeared and Cleisthenes held a banquet in his guests' honour. Cleisthenes preferred the former archon Hippocleides but, during the dinner Hippocleides embarrassed himself.
According to Herodotus, Hippocleides became intoxicated and began to act like a fool; at one point he stood on his head and kicked his legs in the air, keeping time with the flute music. When Hippocleides was informed that he had "danced away his bride," his response was ου φροντις 'Ιπποκλειδη, ("Hippocleides doesn't care" or "It doesn't matter to Hippocleides"). After these unfortunate events, Megacles of the Alcmaeonid clan was chosen to marry Agariste, who gave birth to two sons, Hippocrates and Cleisthenes, the reformer of the Athenian democracy. Hippocrates was father of another Megacles (ostracized 486 BC) and a daughter Agariste was mother of Pericles and Ariphron (himself the father of Hippocrates of Athens who died 424 BC). The younger son Cleisthenes was allegedly father of Deinomache (or Dinomache), mother of Alcibiades (d. 404 BC) In either scenario, Agariste was a common ancestress of Pericles and Alcibiades. W. K. Lacey felt that Agariste was an epikleros, or heiress who was required to have children to perpetuate her father's family.
