(Κλεόβουλος), ephor with Xenares at Sparta B. C. 422-1, the second year of the peace of Nicias. To this peace they were hostile, and signalized their ephoralty by an intrigue with the Boeotians and Corinthians, with the purpose of forming anew the Lacedaemonian league so as to include the Argives, the fear of whose hostility was the main obstacle in the way of the war-party at Sparta. (Thuc. 5.36-38.)
