Hadrian arrived in Greece during the autumn of 124, and participated in the Eleusinian Mysteries. He had a particular commitment to Athens, which had previously granted him citizenship and an ; at the Athenians' request, he revised their constitution – among other things, he added a new phyle (tribe), which was named after him. Hadrian combined active, hands-on interventions with cautious restraint. He refused to intervene in a local dispute between producers of olive oil and the Athenian Assembly and Council, who had imposed production quotas on oil producers; yet he granted an imperial subsidy for the Athenian grain supply. Hadrian created two foundations, to fund Athens' public games, festivals and competitions if no citizen proved wealthy or willing enough to sponsor them as a Gymnasiarch or Agonothetes. Generally Hadrian preferred that Greek notables, including priests of the Imperial cult, focus on more durable provisions, such as aqueducts and public fountains ("nymphaea"). Athens was given two such fountains; another was given to Argos.
