Herodotus 1.71

Meanwhile Crœsus, mistaking the meaning of the oracle, was making a march into Cappadokia, expecting to overthrow Cyrus and the power of the Persians: and while Crœsus was preparing to march against the Persians, one of the Lydians, who even before this time was thought to be a wise man but in consequence of this opinion got a very great name for wisdom among the Lydians, had advised Crœsus as follows (the name of the man was Sandanis):—“O king, thou art preparing to march against men who wear breeches of leather, and the rest of their clothing is of leather also; and they eat food not such as they desire but such as they can obtain, dwelling in a land which is rugged; and moreover they make no use of wine but drink water; and no figs have they for dessert, nor any other good thing. On the one hand, if thou shalt overcome them, what wilt thou take away from them, seeing they have nothing? and on the other hand, if thou shalt be overcome, consider how many good things thou wilt lose; for once having tasted our good things, they will cling to them fast and it will not be possible to drive them away. I for my own part feel gratitude to the gods that they do not put it into the minds of the Persians to march against the Lydians.” Thus he spoke not persuading Crœsus: for it is true indeed that the Persians before they subdued the Lydians had no luxury nor any good thing.
