The Henotikon (/həˈnɒtɪkən/ or /həˈnɒtɪˌkɒn/ in English; Greek ἑνωτικόν henōtikón "act of union") was a christological document issued by Byzantine emperor Zeno in 482, in an unsuccessful attempt to reconcile the differences between the supporters of the Council of Chalcedon and the council's opponents. It was followed by the Acacian schism.[1]
