Hadrian's movements after his journey down the Nile are uncertain. Whether or not he returned to Rome, he travelled in the East during 130/131, to organise and inaugurate his new Panhellenion, which was to be focused on the Athenian Temple to Olympian Zeus. As local conflicts had led to the failure of the previous scheme for an Hellenic association centered on Delphi, Hadrian decided instead for a grand league of all Greek cities. Successful applications for membership involved mythologised or fabricated claims to Greek origins, and affirmations of loyalty to Imperial Rome, to satisfy Hadrian's personal, idealised notions of Hellenism. Hadrian saw himself as protector of Greek culture and the "liberties" of Greece – in this case, urban self-government. It allowed Hadrian to appear as the fictive heir to Pericles, who supposedly had convened a previous Panhellenic Congress – such a Congress is mentioned only in Pericles' biography by Plutarch, who respected Rome's Imperial order.
