King Xerxes encamped in the Trachinian territory of Malis, and the Greeks in the pass. This spot is called by most of the Greeks, “Thermopylae,” but by the inhabitants and neighbors, “Pylae,” Both parties, then, encamped in these places. The one was in possession of all the parts toward the north as far as Trachis, and the others, of the parts which stretch toward the south and meridian of this continent.
The following were the Greeks who awaited the Persians in this position. Of Spartans, three hundred heavy-armed men; of Tegeans and Mantineans, one thousand (half of each); from Orchomenus in Arcadia, one hundred and twenty; and from the rest of Arcadia, one thousand (there were so many Arcadians); from Corinth, four hundred; from Phlius, two hundred men; and from Mycenae, eighty. These came from Peloponnesus. From Boeotia, of Thespians seven hundred; and of Thebans, four hundred.
In addition to these, the Opuntian Locrians, being invited, came with all their forces, and a thousand Phocians; for the Greeks themselves had invited them, representing by their embassadors that “they had arrived as forerunners of the others, and that the rest of the allies might be daily expected; that the sea was protected by them, being guarded by the Athenians, the AEginetae, and others, who were appointed to the naval service; and that they had nothing to fear, for that it was not a god who invaded Greece, but a man; and that there never was, and never would be, any mortal who had not evil mixed with his prosperity from his very birth, and to the greatest of them the greatest reverses happen; that it must therefore needs be that he who is marching against us, being a mortal, will be disappointed in his expectation.” They, having heard this, marched with assistance to Trachis.
These nations had separate generals for their several cities, but the one most admired, and who commanded the whole army, was a Lacedaemonian, Leonidas, son of Anaxandrides, son of Leon, son of Eurycratides, son of Anaxander, son of Eurycates, son of Polydorus, son of Alcamenes, son of Teleclus, son of Archelaus, son of Agesilaus, son of Doryssus, son of Leobotes, son of Echestratus, son of Agis, son of Eurysthenes, son of Aristodemus, son of Aristomachus, son of Cleodaeus, son of Hyllus, son of Hercules, who had unexpectedly succeeded to the throne of Sparta.
