Quartigod son of Theseus by Phaedra; brother of Acamas. Trojan War veteran. King of Athens after Menestheus. Received the Heraclidae per Euripides' Heraclidae — the canonical foundation of the Athenian-Heraclidae solidarity-tradition that grounded the historical Spartan-Athenian early diplomacy. The Phyllis-Thracian-suicide cycle (Apollod. Epit. 6.16-17; Lucian De Salt. 40) is the canonical aetiology for the almond-tree blossoming.
