Interpretations of Euripides’ Heracles often focus on Theseus’ and Heracles’ cooperative social values in the final scene as a culmination of themes of philia. I argue that the relationship Theseus forges competes with Heracles’ attachment to his household, oikos, which is the central social relationship Euripides describes. The drama consistently develops Heracles as his household's leader by inviting the audience to compare Heracles with interim caretakers Megara and Amphitryon, and later through the protagonist's performance of emotional attachment before and after his madness. The closing scene continues to reveal the value and vulnerability of household attachment by accentuating Heracles’ exclusion from the identity of human family member. This trajectory suggests a painful misalignment between Heracles’ experience in the oikos and the public position Theseus offers at Athens: of a semi-divine hero receiving public cult and honours. Euripides emphasizes this tension to distinguish the experience of oikos-membership.
