From the Neo-Babylonian period to Hellenistic times, the kings ruling over Babylonia employed many ways to disseminate their ideology to the people living under their rule. This article explores how objects – garments, accessories, and other regalia – were used as a corporeal language to express the nature of the king’s powers. These royal attributes are mentioned in royal inscriptions and in certain rituals, while some of them can be seen in iconographic representations of the Babylonian kings found on stelas or sculpted reliefs. Through these textual and iconographic sources, it is possible to observe what messages royal dress conveyed in terms of the origin of power, the identity of the royal person, and the discourse towards the governed people. Although the clothes of kings are the best documented, there is also information on the clothes of queens. For queens too, apparel expressed their status and power. The messages conveyed by royal dress evolved when the rulers were of local origin (Babylonian) and when they were foreign (Persian and Greek), but royal apparel itself remained an important medium for the expression of royal ideology.
