The Council of Nicaea of 325 published 20 canons. The Arabic translation enlarges the collection in two versions which are substantially the same and differ only in the arrangement of the canons. One version has 80 canons Mansi 2, 947-982, the other 84 Mansi 2, 982-1010. They were discovered in the West in the 16th c. by Giovanni Battista Romano and were immediately translated into Latin; the translation of the second collection goes back to Abraham Ecchellensis. They come from the Melkite church and were later accepted by the Coptic and Chaldean churches Maruta of Maipherqat. CPG 8523; Hfl-Lecl 1, 511-523; W.
