Note 171 — PROMETHEUS BOUND

So Io was represented, we are told, by Greek sculptors (Herod. ii. 41), as Isis was by those of Egypt. The points of contact between the myth of Io and that of Prometheus, as adopted, or perhaps developed, by Æschylos are—(1) that from her the destined deliverer of the chained Titan is to come; (2) that both were suffering from the cruelty of Zeus; (3) that the wanderings of Io gave scope for the wild tales of far countries on which the imagination of the Athenians fed greedily. But, as the Suppliants may serve to show, the story itself had a strange fascination for him. In the birth of Epaphos, and Io's release from her frenzy, he saw, it may be, a reconciliation of what had seemed hard to reconcile, a solution of the problems of the world, like in kind to that which was shadowed forth in the lost Prometheus Unbound.
