Question: What's the Ancient History of the Olympic Torch?
The modern Olympics have a torch relay ceremony that's central to the event. What was the ancient Olympic torch ceremony?
The ancient Olympics did not have a torch relay. The lighting event began in 1936 for the Berlin Olympics. There may have been torch events at other ancient panhellenic events and there was an Olympic flame, but not an Olympic torch relay.
There was also a religious procession from Elis to Olympia that began two days early and was led by the Olympic officials with their staff, followed by the athletes and trainers.
The Panathenaia festival had a torch relay, though. See Panhellenic Games.
