Now for this prophecy, which Mardonius said was spoken of the Persians, I know it to have been made concerning not them but the Illyrians and the army of the Enchelees.Referring to a legendary expedition of these northwestern tribes, directed against Greece [22,39] (nation), EuropeHellas and Delphi [22.5167,38.4917] (Perseus) Delphi in particular. There is, however, a prophecy made by Bacis concerning this battle:

By Thermodon's stream and the grass-grown banks of Asopus,Will be a gathering of Greeks for fight and the ring of the barbarian's war-cry;Many a Median archer, by death untimely overtaken will fallThere in the battle when the day of his doom is upon him. I know that these verses and others very similar to them from Musaeus referred to the Persians. As for the river Thermodon, it flows between +Tanagra [23.6,38.3083] (Perseus) Tanagra and +Glisas [23.4167,38.2833] (Perseus) Glisas.A little to the northwest of Thebes [23.3333,38.325] (Perseus) Thebes.
