This seal ring is inscribed with the name 'Baidu' at the top, most probably referring to Baidu, the son of Taraḡāy and grandson of Hülegü, the famed Mongol ruler who founded the Ilkhanid dynasty in Iran. Unlike his grandfather, Baidu's reign as Ilkhan was shortlived, lasting only for eight months, from March to October 1295 before being executed by his cousin Ghazan. This ring, inscribed in reverse for the purpose of seal marking must belong to this short period of history, a rare surviving artefact.
