Bull-slaying - the central icon of the Mithraic faith - is an age-old Near Eastern motif associated with kings, legendary heroes, and gods in both textual and visual sources. The cult of Mithra, originally a Persian god, became popular among Roman soldiers in the 2nd and 3rd centuries CE. A “mystery religion” whose practice was reserved for initiates, its cult centered on personal salvation. The Greek inscription on this relief, mentioning the West Semitic name Absalmos, indicates the object’s origin in the eastern part of the Roman Empire.
