In recent years, there has been a growing interest in analyzing the manufacturing techniques of Byzantine church doors in laboratory settings. However, the connection between the iconography and significance of the décor of church doors and their liturgical performativity, as well as their parallels with iconostases in Byzantium, remained a relatively underexplored area of study. This article seeks to delve deeper into these intersections. By focusing on the relationship between the iconography of church doors in Middle to Late Byzantium and their connection to the sacred space and liturgical practices, I aim to shed light on how these artworks played a crucial role in the sacred experience of the Byzantines. This exploration will not highlight only the aesthetic evolution of church door artwork but also emphasize the communal and embodied nature of the religious experience during the Byzantine era. Their intricate designs were not merely decorative elements but served as portals to the divine, enriching the salvation journey of worshippers as they crossed the threshold into the liturgical spaces. By conducting an examination of the development of door iconography and their symbolism throughout the empire’s history, the transformation of narrative depictions from the Middle Byzantine era to the Palaiologan period, culminating in a convergence of symbolic meanings within the sacred space of the church, is delineated. This transformation is further exemplified by a sculpted church door from the Principality of Wallachia. By bridging the gap between art history and religious studies, this article aims to rekindle interest in the profound symbolism and significance of Byzantine church doors and their relation to sacred liturgical space, offering a broader perspective on an important aspect of Byzantine heritage.
