It is plain to me by this piece of evidence among many others, that while Leonidas lived, king Xerxes was more incensed against him than against all others; otherwise he would never have dealt so outrageously with his dead body, for the Persians are beyond all men known in the habit of honoring valiant warriors. They, then, who received these orders did as I have said.
I return now to that place in my history where it earlier left off.[*](Hdt. 7.220, where Herodotus mentioned the bare fact of the Spartans getting early intelligence of Xerxes' plans against Greece [22,39] (nation), EuropeGreece. Now he completes the story.) The Lacedaemonians were the first to be informed that the king was equipping himself to attack Greece [22,39] (nation), EuropeHellas; with this knowledge it was that they sent to the oracle at Delphi [22.5167,38.4917] (Perseus) Delphi, where they received the answer about which I spoke a little while ago. Now the way in which they were informed of this was strange.
Demaratus son of Ariston, an exile among the Medes, was, as I suppose (reason being also my ally), no friend to the Lacedaemonians, and I leave it to be imagined whether what he did was done out of goodwill or spiteful triumph. When Xerxes was resolved to march against Greece [22,39] (nation), EuropeHellas, Demaratus, who was then at Shush [48.333,32.2] (inhabited place), Khuzestan, Iran, AsiaSusa and had knowledge of this, desired to send word of it to the Lacedaemonians.
