Stole (Latin, stola).
An ecclesiastical vestment, also called the Orarium. Deinde circumdat collum suum stola, qu et Orarium dicitur. It indicates Obedientiam fiilii Dei et jugum servitutis, quod pro salute hominum portvit. Deacons wear the stole over the left shoulder, and loop the two parts together, that they may both hang on the right side. Priests wear it over both shoulders. (See Ducange: Stola.)
