Phaedriades

In Greece, the Phaedriades (Φαιδριάδες, meaning "the shining ones")[1] are the pair of cliffs, ca 700 m high on the lower southern slope of Mt.

Strabo, Plutarch and Pausanias all mentioned the Phaedriades when describing the site, a narrow valley of the Pleistos (today Xeropotamos) formed by Parnassos and Mount Cirphis.

Indeed, as the Persian army approached, thunderbolts fell from the sky and killed several of the enemy.

Defensive weapons appeared magically in front of the temple of Apollo and of that of Athena Pronaia.

Herodotus mentions that in his day, one could see these rocks embedded in the ground within the sacred precinct of Athena Pronaia.
