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 (117-138) was particularly fond of the Greeks, particularly Athens. He saw himself as an heir to Theseus and Pericles and had served as an eponymous archon of Athens before he became emperor. He carried out constitutional reforms at Athens in 126 and instituted a special 'council of the Panhellenes', where representatives of all Greek states met to discuss religious affairs, in Athens and under Athenian leadership. Hadrian was also responsible for large scale construction projects there, such as the completion of the Temple of Olympian Zeus and the Athenians built the Arch of Hadrian in his honour nearby. Construction was also carried out by local notables, many of whom became Roman citizens and joined the Imperial elite, most notably Herodes Atticus.
