The aim of the study is to present the types of royal attire of the Cilician Kingdom as depicted in secularized representations derived from Christological imagery, to identify the national elements expressed in them, and to compare them with Western and Byzantine court costume traditions. The topic is relevant, as the interpretation of the structural and decorative features of royal attire from a new perspective may contribute to a deeper understanding of Cilician Armenian culture. This research may serve as a guide for scholars of medieval Armenian manuscript illumination and traditional national costume.
