The scapular (from Latin scapulae, "shoulders") is a Western Christian garment suspended from the shoulders. There are two types of scapulars, the monastic and devotional scapular, although both forms may simply be referred to as "scapular". As an object of popular piety, it serves to remind the wearers of their commitment to live a Christian life.
The "monastic scapular" appeared first, perhaps as early as the 7th century in the Order of Saint Benedict. It is a length of cloth suspended both front and back from the shoulders of the wearer, often reaching to the knees. It may vary in shape, color, size and style. Monastic scapulars originated as aprons worn by medieval monks, and were later extended to habits for members of religious organizations, orders or confraternities. Monastic scapulars now form part of the habit of monks and nuns in many Christian orders.
The "devotional scapular" is a much smaller item and evolved from the monastic scapular. These may also be worn by individuals who are not members of a monastic order. The devotional scapular typically consists of two small (usually rectangular) pieces of cloth, wood or laminated paper, a few inches in size, which may bear religious images or text. These are joined by two bands of cloth and the wearer places one square on the chest, rests the bands one on each shoulder and lets the second square drop down the back.
