epitaphion
An embroidered veil showing the dead body of Jesus Christ.
Visitors kept dropping by, following the custom of seeing as many epitaphoi as possible; the more you visit, the better your luck for the coming year. I crawled under the epitaphion, too, and Spiridoula tipped me off that people take flowers from the epitaphion home with them after the evening service to save as filakta — protective amulets.
Where it comes from
Borrowed from Ancient Greek ἐπῐτᾰ́φῐον (epĭtắphĭon).
