Quinarius - Amdān Bayān Yahaqbiḍ Raydan

The Himyarite quinarius series occupies a strange position in South Arabian numismatics — technically derivative of the Roman quinarius in weight and module, yet thoroughly local in execution, produced by a kingdom that controlled the frankincense and myrrh trade routes linking the Arabian interior to Roman and Aksumite markets. Amdān Bayān Yahaqbiḍ was a Himyarite ruler of the early second century whose exact regnal dates remain debated, the South Arabian epigraphic record giving us his name but not clean chronological anchors.

The Raydan designation refers to the ancient royal palace and seat of Himyarite power near modern Ẓafār in Yemen.
