Who exactly was condemned in 553

The fifth ecumenical council anathematised Origen, and the three men usually named with him were not all named by it. Canon 11 of Constantinople II lists Origen alone among the ancient heretics it condemns. It is the later councils that recite the fuller list — the Quinisext, Constantinople III and Nicaea II all repeat an anathema naming Origen with Didymus and Evagrius — and it is that recitation, not the fifth council's own canon, that fixed the three names together. There is a further complication this dataset does not attempt to settle: whether the fifteen anathemas against the Origenists that circulate with the council were passed by it at all, or were the work of a synod at Constantinople ten years earlier under Justinian and were attached to the acts afterwards. What is not in doubt is the effect. Didymus had run the Alexandrian school and taught Jerome; Evagrius had been archdeacon of the capital under Gregory of Nazianzus and is the source of the eight thoughts that became the seven deadly sins in the West. Both are condemned here, by name, a century and a half after they died, largely for the last of Evagrius's books.
