Following the Sasanian conquest of Bactria-Tukhāristān in the third century CE, Kushan cultic traditions centred on the veneration of anthropomorphic divine images continued to thrive under the new Persian rulers. Rather than imposing aniconic Zoroastrian practices, the Sasanians actively patronised local religious customs, commissioning statues of Persian deities such as Anāhitā while incorporating Bactrian gods into their visual and ritual repertoire. Numismatic and architectural evidence reflects this synthesis: Kushano-Sasanian coinage preserves the Kushan pantheon, with deities depicted in novel forms, including enthroned figures and busts emerging from fire altars, while temples at Surkh Kotal and Dilberjin combined divine statues with the veneration of the sacred fire. The coexistence of Bactrian and Middle Persian in inscriptions suggests a broader process of cultural adaptation. The persistence of these practices under subsequent Hunnic rule, and their later diffusion into Sogdiana, demonstrates their long-term impact on the religious landscape of Central Asia. The Kushano-Sasanian period thus marks the emergence of a distinctive cultic tradition, shaped by the cultic fusion, which continued to influence the region long after the decline of Sasanian rule.
