COENOBITE, n.  A man who piously shuts himself up to meditate upon the
sin of wickedness; and to keep it fresh in his mind joins a
brotherhood of awful examples.

    O Coenobite, O coenobite,
        Monastical gregarian,
    You differ from the anchorite,
        That solitudinarian:
    With vollied prayers you wound Old Nick;
    With dropping shots he makes him sick.
