The Argives say this was the reason Cleomenes went mad and met an evil end; the Spartans themselves say that Cleomenes' madness arose from no divine agent, but that by consorting with Scythians he became a drinker of strong wine, and the madness came from this.

The nomadic Scythians, after Darius had invaded their land, were eager for revenge, so they sent to Sparta [22.4417,37.0667] (Perseus) Sparta and made an alliance. They agreed that the Scythians would attempt to invade Media by way of the river +Poti [41.683,42.183] (inhabited place), regions under republican jurisdiction, Georgia, Asia Phasis, and they urged the Spartans to set out and march inland from +Ephesus [27.316,37.916] (deserted settlement), Izmir Ili, Ege kiyilari, Turkey, Asia Ephesus and meet the Scythians.

They say that when the Scythians had come for this purpose, Cleomenes kept rather close company with them, and by consorting with them more than was fitting he learned from them to drink strong wine. The Spartans consider him to have gone mad from this. Ever since, as they themselves say, whenever they desire a strong drink they call for “a Scythian cup.” Such is the Spartan story of Cleomenes; but to my thinking it was for what he did to Demaratus that he was punished thus.
