Histories

The Persians saw them running to attack and prepared to receive them, thinking the Athenians absolutely crazy, since they saw how few of them there were and that they ran up so fast without either cavalry or archers.

So the foreigners imagined, but when the Athenians all together fell upon the foreigners they fought in a way worthy of record. These are the first Hellenes whom we know of to use running against the enemy. They are also the first to endure looking at Median dress and men wearing it, for up until then just hearing the name of the Medes caused the Hellenes to panic.
