The '''aer''' (literally the "air"; modern Greek: Αέρας; Slavonic: ''Воздухъ'', ''Vózdukh'') is a veil used for covering the [[paten]] and [[chalice]] during and after the [[Eucharist]]. The [[priest]] shakes the aer over the chalice when the [[Nicene-Constantinopolitan Creed|creed]] is read; this symbolizes the descent of the [[Holy Spirit]]. The aer also represents the shroud of [[Christ]].

In the [[Liturgy of the Presanctified Gifts]], the aer covers the head of the priest during the [[ Great Entrance]].
