1998, Encyclopaedia Britannica CD 98 Multimedia Edition:
The bishop wears an omophorion, whose shape and manner of wearing are closer to the original pallium than either the stole or the epitrachelion.
2001, “The Symbolism of Vestments”, in Orthodox America, archived from the original on 21 January 2001:
Although the bishop also wears - an epitrachelion, his distinctive sign of office is the omophorion-a long, broad strip arranged on the shoulders in such a way that one end descends in front and the other behind. The word 'omophorion' means "shoulder covering" and originally referred to a piece of sheepskin worn over the shoulders by the aged and in firm for warmth.
