Panegyricon (πανηγυρικόν, flattering) is the title of an Eastern Church collection of sermons by the most approved authors of the Christian Church on different festivals. Almost every province in the East has a separate collection, and the consequence is that the book remains in MS. form. Sometimes on very high festivals the sermon for the day is transcribed into the Menea, an Eastern office-book corresponding to the Breviary (q.v.), or other office- books, as was that of St. Chrysostom into the Pentecostarion (q.v.) for Easterday. See Neale, Introd. to the Hist. of the East. Ch. vol. ii, ch. iii, esp. p. 889.
