Amphibalus is a term that refers to a type of cloak or garment worn in ancient times, particularly in the context of Roman and early Christian attire. It was typically made of wool and designed to be worn over other clothing for warmth and protection. The amphibalus often had a hood and was used by various groups, including clergy and laypeople. In Christian tradition, the amphibalus is sometimes associated with the attire of saints, such as Saint Alban, who is considered the first British martyr. The garment symbolizes both religious devotion and the cultural practices of the time, reflecting the blending of Roman and early Christian styles.
