126 THE HISTORY OF HERODOTUS.

not swim were drowned and those who could, died of cold. Mardonius himself received a wound in an action on the mainland of Thrace, and the expedition returned home with its commander in- valided. Darius immediately made fresh prepara- tions, and sent heralds to all the Greek states to de- mand earth and water, in order that he might know what support to expect. It is to be hoped that the Athenians and Spartans did not disgrace them- selves by throwing one of the heralds into a well and the other into a pit, and telling them to fetch earth and water thence ; but such is the story. Darius himself would under no provocation have so forgotten his knighthood. Some years afterwards, the Spartans were said to have sent two of their citizens, who voluntarily offered themselves, to Susa, as an atone- ment for this outrage, for which they believed that the wrath of the hero Talthybius, the patron of heralds, lay heavy on them; but Xerxes, who was then king, would not accept the sacrifice, and dismissed them unhurt. The ^Eginetans gave the earth and water to Darius, probably to spite the Athenians, who at once denounced them to the Spartans (who were as yet considered the leaders of Greece) as traitors to the national cause. The Spartan king Cleomenes went to -ZEgina to arrest the most guilty parties; but his mission there was foiled by his brother-king Demaratus, who was accusing him at home. In retaliation, Cleomenes attempted to prove that Demaratus was illegitimate. His mother was the loveliest woman in Sparta. She had been ugly in her childhood, but was changed into a beauty by her nurse taking her daily to the temple of Helen.
