Narrative
When the earth opened and took Amphiaraus, his chariot, and his charioteer Baton (or Elatos) before Periclymenus could spear him, Zeus made him immortal. At Oropos on the border of Attica and Boeotia a sanctuary grew where Amphiaraus was honored as a chthonic healer and oracle. Pausanias describes the altar of gods and heroes, the spring by which no oath-breaker might swear, and the rite of incubation: the consultant purified, sacrificed a ram, spread its skin, and slept awaiting a dream-answer—cures and counsel alike.
Herodotus already lists Amphiaraus among oracles Croesus tested and notes Theban consultation rules. The living seer who foresaw his death at Thebes thus becomes, in local cult, an underworld voice reached through sleep on the sacrificed skin—bridging Seven Against Thebes narrative and Attic–Boeotian pilgrimage.
