 The phelonion was at first part of the bishop's vestments but was replaced by a garment, similar to the deacon's sticharion, called a sakkos (also "saccos"), a representing humility.As Christ's robe was without seam, the bishop, as an icon of Christ, wears the saccos either sewn or buttoned at the sides.Over the saccos, the bishop wears a wide shoulder covering called the omophorion.
