The Roman Emperor Nero visited Greece in AD 66, and performed at the Ancient Olympic Games, despite the rules against non-Greek participation. He was honoured with a victory in every contest, and in the following year, he proclaimed the freedom of the Greeks at the Isthmian Games in Corinth, just as Flamininus had over 200 years previously. Hadrian was also particularly fond of the Greeks; before he became emperor he had served as an eponymous archon of Athens. He also finished the Temple of Zeus there and the Athenians built the Arch of Hadrian in his honour nearby.
