The ancient Olympic Games (Ancient Greek: τὰ Ὀλύμπια, ta Olympia), or the ancient Olympics, were a series of athletic competitions among representatives of city-states and one of the Panhellenic Games of ancient Greece. They were held at the Panhellenic religious sanctuary of Olympia, in honor of Zeus, and the Greeks gave them a mythological origin. The originating Olympic Games are traditionally dated to 776 BC. The games were held every four years, or Olympiad, which became a unit of time in historical chronologies. These Olympiads were referred to based on the winner of their stadion sprint, e.g., "the third year of the eighteenth Olympiad when Ladas of Argos won the stadion". They continued to be celebrated when Greece came under Roman rule in the 2nd century BC. Their last recorded celebration was in AD 393, under the emperor Theodosius I, but archaeological evidence indicates that some games were still held after this date. The games likely came to an end under Theodosius II, possibly in connection with a fire that burned down the temple of the Olympian Zeus during his reign.
During the celebration of the games, the Olympic truce (ekecheiría) was announced so that athletes and religious pilgrims could travel from their cities to the games in safety. The prizes for the victors were olive leaf wreaths or crowns. The games became a political tool used by city-states to assert dominance over their rival city-states. Politicians would announce political alliances at the games, and in times of war, priests would offer sacrifices to the gods for victory. The games were also used to help spread Hellenistic culture throughout the Mediterranean. The Olympics also featured religious celebrations. The statue of Zeus at Olympia was counted as one of the seven wonders of the ancient world. Sculptors and poets would congregate each Olympiad to display their works of art to would-be patrons.
