Because Isaac Komnenos failed to return to imperial service, Byzantine emperor Andronikos I Komnenos ordered Constantine Makrodoukas and Andronikos Doukas arrested for treason, although Constantine had heretofore loyally supported the emperor. The courtier Stephen Hagiochristophorites conducted a water-oracle that gave the letter I (iota) as the initial of the succeeding emperor, so Byzantine emperor Andronikos I feared an attempt of Isaac to usurp the throne. On 30 May 1185, as court officials led Andronikos Doukas and Constantine from prison to face the charges, Hagiochristophorites incited the watching crowd to stone both men to death.
