530 BC – Harmodius was born.
514 BC – Hipparchus sought the sexual favours of Harmodius, who was, the historian Thucydides tells us, "then in the flower of youthful beauty," which would have made him about fifteen.
– Harmodius rejected Hipparchus and told Aristogeiton what had happened. Hipparchus, spurned, avenged himself by having Harmodius’ young sister disqualified from carrying a ceremonial offering basket at the Panathenaea festival on the pretext she was not a virgin, as required.
514 BC – Harmodius died.
