This paper argues that Lycophron's Alexandra follows earlier texts in presenting challenges to Agamemnon's power as metaphorical re-enactments of primordial theogonic conflicts between Zeus and the forces of chaos. The Alexandra figures Agamemnon as Zeus and portrays Achilles, Clytemnestra and Cassandra as chthonic monsters opposed to the Olympian order. Employing intertexts with epic and tragedy, the poem highlights these figures’ symbolic antagonism with Agamemnon–Zeus and their connections to each other. It presents a radically resystematized vision of the cosmos that champions the chthonic, the disordered and the feminine over the Olympian, the ordered and the masculine. Cassandra uses this backdrop to reinterpret her own story, inserting herself into the cosmogonic narrative as a resister of Olympian patriarchy who triumphs over masculine domination.
