Disguise in the ritual performance of Shabih is considered a ritual technique rooted in ancient mythological, religious, and social beliefs. Ritual performance is a collective and social activity that encompasses various forms of speech, symbolic actions, and movements directly related to spirituality and the sacred. This article specifically focuses on identifying the types of disguises performed by performers in Shabih (Ta’ziyeh). It aims to classify and reveal these disguises, and by examining their connections to ancient Iranian rituals and ceremonies, it raises the question of which ritualistic, religious, and cultural origins can be recognized in the act of disguise within Shabih performances. This research is conducted through a descriptive and analytical method, based on library sources as well as visual documents. Based on the posed question, and presenting an original classification of the types of disguises used by performers in Shabih plays, the study demonstrates that various disguise techniques reflect ancient rituals embedded within the beliefs, ritual ceremonies, religion, and longstanding culture of the Iranian nation.
