THEOPISTUS OF ALEXANDRIA
Nothing is known about him. He is not commemorated in the Synaxarion or in any Coptic liturgical book. The name of Alexandria could be misleading by the connotation that he was a patriarch of that city, but no patriarch bore this name.
It has been suggested that he could be identified as one of the followers of Dioscorus I to the Council of Chalcedon. He could be the one mentioned in the panegyric of Macarius of Tkow by Dioscorus of Alexandria.
