The hexapterygon or ripidion is a ceremonial fan used in the Eastern Christian Churches (including Eastern Catholic Churches, Eastern Orthodox Churches and Oriental Orthodox Churches) during services. Ripidia are carried by the altar servers at all processions with Eucharistic gifts and the Gospel book.
In the Eastern Catholic Churches and Eastern Orthodox Churches, the sacred εξαπτέρυγον, hexapterygon, plural: εξαπτέρυγα hexapteryga—literally, "six-winged"), have been used from the first centuries to the present day. It is generally made of metal, round, having the iconographic likeness of an angel with six wings, and is set on the end of a pole. Hexapteryga of carved, gilded, or painted wood are also found. They are usually made in pairs. For historical use in the Western Church see flabellum.
Among the Eastern Catholics and Eastern Orthodox, the hexapteryga will be carried during the Great Entrance and at all processions; in the Russian churches they are often also used to honour a particularly sacred icon or relic. When not in use, the hexapteryga are usually kept in stands behind the Holy Table in the Byzantine Eastern Catholic Churches and Greek tradition, and in the Slavic traditions may either be kept there or out of sight elsewhere in the altar. The latter is especially true in northern Russia, where icons of Christ and the Theotokos are usually placed behind the Holy Table.
Hexapteryga used in the Maronite and Oriental (e.g., Coptic, Armenian, Ethiopian) traditions are distinctive, having little hoops of metal or bells all around the circumference of the disks, symbolizing the hymns of the angels to God. At particularly solemn points of the liturgy, these are shaken gently to produce a tinkling and jingling sound, akin to the sound of multiple altar bells.
