It takes its name either from the lightness of the material of which it is made, or from the fact that during the Nicene Creed in the Divine Liturgy, the priest holds it high in the air and waves it slowly over the Chalice and Diskos. Its original use was to cover the Chalice and prevent anything from falling into it before the consecration. It symbolizes the swaddling clothes with which Christ was wrapped at his Nativity, and also the grave clothes in which he was wrapped at his burial (both themes are found in the text of the Liturgy of Preparation).
