While these worked at their appointed task, all the land force had been mustered and was marching with Xerxes to Sardis, setting forth from Critalla in Cappadocia, which was the place appointed for gathering all the army that was to march with Xerxes himself by land. Now which of his governors received the promised gifts from the king for bringing the best-equipped army, I cannot say; I do not even know if the matter was ever determined. When they had crossed the river Halys and entered Phrygia, they marched through that country to Celaenae, where rises the source of the river Maeander and of another river no smaller, which is called Cataractes; it rises right in the market-place of Celaenae and issues into the Maeander. The skin of Marsyas the Silenus also hangs there; the Phrygian story tells that it was flayed off him and hung up by Apollo.
