Abstract There exists widespread evidence that the Near Eastern societies manufactured seals. However, among these, South Arabian seals remain largely neglected while performing various particularly revealing functions. For instance, the practice of sealing allowed for the explicit expression of ownership as well as the act of witnessing in legal matters. More broadly, seals were a means of articulating individual identities and reinforcing communal belonging. This paper is the first study on the seals of ancient South Arabia after the unpublished Ph.D. dissertation by Diana P. Wong (1999. “Stamp Seals of the Ancient Yemen.” Unpublished PhD diss., Berkely). It investigates a corpus comprising 85 published seals currently held in museums and private collections across three continents. After providing a brief survey of the region’s history, this article analyses the epigraphic and iconographic content carved on the corpus, offering some reflections on the typology and characteristics of the seals, as well as on the society of ancient South Arabia.
