Chrys. in Matt. Hom. lxxiv. § 3: “You ought to have within you the wall that separates you from the women: but since ye will not, our fathers have thought it necessary to separate you at least by these boards; for I have heard from my elders that there were not these walls in old times.” These barriers had not yet been introduced at Jerusalem, or Cyril’s admonition would have been needless. Compare Apostolic Constitutions, II. 57.
