he Alb is a vestment that can trace its origin to six ancient garments: the Kolobus, the Tunica, the Colobim, the Tunica Talaris, the Subucula, and finally the Tunica Alba. These garments were common in Greek or Roman times, some garments being used by both cultures. They are not six manifestations of one garment, but rather six that are distinct enough to make note of the differences.
