In September 128, Hadrian attended the Eleusinian mysteries again. This time his visit to Greece seems to have concentrated on Athens and Sparta – the two ancient rivals for dominance of Greece. Hadrian had played with the idea of focusing his Greek revival around the Amphictyonic League based in Delphi, but by now he had decided on something far grander. His new Panhellenion was going to be a council that would bring Greek cities together. Having set in motion the preparations – deciding whose claim to be a Greek city was genuine would take time – Hadrian set off for Ephesus. From Greece, Hadrian proceeded by way of Asia to Egypt, probably conveyed across the Aegean with his entourage by an Ephesian merchant, Lucius Erastus. Hadrian later sent a letter to the Council of Ephesus, supporting Erastus as a worthy candidate for town councillor and offering to pay the requisite fee.
