Epiphanies tend to have been reported more frequently at times of extreme danger, such as the Persian Wars. For example, at the Battle of Marathon in 490 it was said that Pan, Theseus, and another hero, fought against the Persians. It was also widely believed that the runner, Pheidippides, on the eve of the battle of Marathon, met with Pan on Mount Parthenion, where the god promised to support the Athenians. After their unexpected victory, the grateful Athenians introduced Pan’s cult into their city.
