Kleomenês and Leotychidês, the two kings of Sparta (the former belonging to the elder, or Eurystheneïd, the latter to the younger, or the Prokleïd, race), had conspired for the purpose of dethroning the former Prokleïd king Demaratus: and Kleomenês had even gone so far as to tamper with the Delphian priestess for this purpose. His manœuvre being betrayed shortly afterwards, he was so alarmed at the displeasure of the Spartans, that he retired into Thessaly, and from thence into Arcadia, where he employed the powerful influence of his regal character and heroic lineage to arm the Arcadian people against his country. The Spartans, alarmed in their turn, voluntarily invited him back with a promise of amnesty. But his renewed lease did not last long: his habitual violence of character became aggravated into decided insanity, insomuch that he struck with his stick whomsoever he met; and his relatives were forced to confine him in chains under a Helot sentinel. By severe menaces, he one day constrained this man to give him his sword, with which he mangled himself dreadfully and perished. So shocking a death was certain to receive a religious interpretation, but which among the misdeeds of his life had drawn down upon him the divine wrath, was a point difficult to determine. Most of the Greeks imputed it to the sin of his having corrupted the Pythian priestess:[73] but the Athenians and Argeians were each disposed to an hypothesis of their own,—the former believed that the gods had thus punished the Spartan king for having cut timber in the sacred grove of Eleusis,—the latter recognized the avenging hand of the hero Argus, whose grove Kleomenês had burnt, along with so many suppliant warriors who had taken sanctuary in it. Without pronouncing between these different suppositions, Herodotus contents himself with expressing his opinion that the miserable death of Kleomenês was an atonement for his conduct to Demaratus. But what surprises us most is, to hear that the Spartans, usually more disposed than other Greeks to refer every striking phenomenon to divine agency, recognized on this occasion nothing but a vulgar physical cause: Kleomenês had gone mad, they affirmed, through habits of intoxication, learned from some Scythian envoys who had come to Sparta.[74] [73] Herodot. vi, 74, 75.
