The epitrachelion (in Greek it means "around the neck") is a liturgical
vestment worn by priests and bishops of the Orthodox Church and Eastern Catholic Churches as the symbol of their priesthood. In effect it is a development of the Orarion, doubled with both ends handing in front and reaching the full length of the tunic or Sticharion. The epitrachelion is usually made of brocade with seven embroidered or appliqued crosses, one at the back of the neck and three down each side. The epitrachelion is the only required vestment whenever a priest is conducting an Orthodox service; without it, he is unable to perform the service.
