The alb, a long, white liturgical vestment worn by Christian clergy, derives its name from the Latin albus ("white") and represents purity, reminiscent of ancient Roman tunics. Historically, it has played a central role in Western Christian rituals, transforming from simple linen garments into elaborate designs after the Council of Trent.
Writers such as John Ruskin and Christopher Whall examined the spiritual significance of color, while medieval records indicated albs in shades other than white, showcasing both practical and symbolic adaptations. The alb's continued use, from Eucharistic worship to contemporary vestments, highlights its fusion of tradition and functional development within Christian practice.
