Our information respecting the affairs of Greece immediately after the repulse of the Persians from Marathon, is very scanty.

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 manoeuvre 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.
