‘‘‘Pallium’’’ or ‘‘‘Pall’’’ is an ecclesiastical vestment used in the [[Church of Rome]] and originally worn only by the [[Bishop]] of Rome. However, it has been bestowed by him for centuries on [[metropolitan]]s and [[primate]]s in the Western Church as a symbol of the jurisdiction delegated to them by the Holy See.
In its present form the pallium is a narrow band of clothe, "three fingers broad," woven of white lamb's wool from sheep raised in Valencia, Spain, with a loop in the centre resting on the shoulders over the chasuble, and two dependent lappets, before and behind. Thus, when seen from front or back the vestment resembles the letter Y. It is decorated with six black crosses, one on each tail and four on the loop, is doubled on the left shoulder, and is garnished, back and front, with three jeweled gold pins.
