This is an exquisite example of a rare type of swallowtail-shaped apron worn by young female initiates until the mid-19th century. On the upper portion, the black beads were applied in such a way that they can be read as a human face or even as a full figure. In fact, the overall form of the apron can be viewed as representing the lower torso and legs of a woman with a neatly marked pubic region.
