Menologium, (from μήν, month, and νόστος, djourfe), is much the same as martyrology, or calendar, in the Latin.

The Greek menologium is divided into the several months in the year; and contains an abridgment of the lives of the saints, with a bare enumeration of the names of such whose lives were never written. The Greeks have various menologies; and the Romans tax them with inferring divers heretics in their menologies as saints.—Baillet treats of them at large.
