After the triptychs came sets of five leaves, hinged together; sometimes these were arranged in groups of four around a central plaque. Often they were intended to be used as book covers. Occasionally the five leaves were made up of classical ivories which had been altered in such a way that they now had Christian significance. The beautiful diptych in the Bargello, representing Adam in the Earthly Paradise, may easily have been originally intended for Orpheus, especially since Eve is absent! The treatment is rather classical, and was probably adapted to its later name. Some diptychs which were used afterwards for ecclesiastical purposes, show signs of having had the Consular inscription erased, and the wax removed, while Christian sentiments were written or incised within the book itself. Parts of the service were also occasionally transcribed on diptychs. In Milan the Rites contain these passages: "The lesson ended, a scholar, vested in a surplice, takes the ivory tablets from the altar or ambo, and ascends the pulpit;" and in another place a similar allusion occurs: "When the Deacon chants the Alleluia, the key bearer for the week hands the ivory tablets to him at the exit of the choir." Anastatius, in his Life of Pope Agatho, tells of a form of posthumous excommunication which was sometimes practised: "They took away from the diptychs... wherever it could be done, the names and figures of these patriarchs, Cyrus, Sergius, Paul, Pyrrhus, and Peter, through whom error had been brought among the orthodox." Among ivory carvings in Carlovingian times may be cited a casket with ornamental colonettes sent by Eginhard to his son. In 823, Louis le Debonaire owned a statuette, a diptych, and a coffer, while in 845 the Archbishop of Rheims placed an order for ivory book covers, for the works of St. Jerome, a Lectionary, and other works.
