Cyrus attended another synod at Cyprus under Arkadios II in 636 along with 45 other senior clergy,[1] at which he served as moderator and permitted Monothelite opponents to submit their case to the Emperor. When Cyrus received the Emperor's Monothelite response, the Ecthesis, Cyrus signed it in 637. Ultimately the monothelete compromise proved ineffective, as it was condemned at the Lateran Council of 649[4] and soon fell into discredit under the contemptuous name of Byzantine Greek: enôsis hydrobaphès, lit. 'washy union'.
