The Saint Euphrosynos Cafe

Thanks for this answer. So its locations are pretty analogous to the purificator in the western rite: kept on the altar during the consecration and removed to the credence afterwards. For function, however, it has as its counterpart the (disused) housling cloth or the (disused) handled paten.

Can anyone tell me the name of the cloth held beneath the chalice and the chin of the communicant?

Is it one of the kalymmata, perhaps the aer?

Where does it sit during the anaphora? What happens to it afterward? Does it have any other function?

Thanks for your help.
