Aristides

The magnitude of their success was known to the Hellenes, not from the multitude of those they slew, for few had fallen, but from the grief of the Barbarians. For they shore their own hair in tribute to Masistius, and that of their horses and mules, and filled the plain with their wailing cries. They felt that they had lost a man who, after Mardonius himself, was by far the first in valor and authority.

After this cavalry battle, both sides refrained from further fighting for a long time, since only as they acted on the defensive would victory be theirs—so the soothsayers interpreted the sacrifices alike for Persians and Hellenes,—but if they attacked, defeat. At last Mardonius, since he had supplies remaining for only a few days, and since the Hellenes were ever increasing in number as fresh bodies joined them, impatiently determined to wait no longer, but to cross the Asopus at daybreak and attack the Athenians unexpectedly. During the evening he gave the watchword to his commanders.
