Note 9 — March 5.
Reading edition
The best account of the Manichæan tenets of the medæval heretics is in Hahn: Geschichte der Ketzer, vol. i.; the texts are given in notes, upon which he bases his opinion. See also Gieseler's Ecclesiastical Hist., 3rd division, chap. vii.; but Gieseler is less full and impartial than Hahn.
