Ripidion
The ripidion, or hexapterygon is a ceremonial fan used in Eastern Christian[note 1] worship.[1][2]
In the Eastern Churches, liturgical fans have been used from the first centuries to the present day. A fan is generally made of metal, round, having the iconographic likeness of a six-winged seraphim and is set on the end of a pole. Fans of carved, gilded, or painted wood are also found. Fans are usually made in pairs.
