Before they left the city, the Athenian generals sent off a message to Sparta. The messenger was an Athenian named Pheidippides, a professional long-distance runner. According to the account he gave the Athenians on his return, Philippides met the god Pan on Mount Parthenium, above Tegea. Pan, he said, called him by name and told him to ask the Athenians why they paid him no attention, in spite of his friendliness towards them and the fact that he had often been useful to them in the past, and would be so again in the future. The Runner reached Sparta the day after he left Athens and delivered his message to the Spartans. “Men of Sparta” (the message ran), “the Athenians ask you to help them, and not to stand by while the most ancient city of Greece is crushed and subdued by a foreign invader; for even now Eretria has been enslaved, and Greece is the weaker by the loss of one fine city.” The Spartans, though moved by the appeal, and willing to send help to Athens, were unable to send it promptly because they did not wish to break their law. It was the ninth day of the month, and they said they could not take the field until the moon was full. So they waited for the full moon, and the Persians sailed to Marathon.”
