With a history of use extending back to Vedic texts of the second millennium BC, derivations of the name Mithra appear in the Roman Empire, across Sasanian Persia, and in the Kushan Empire of southern Afghanistan and northern India during the first millennium AD. Even today, this name has a place in Yazidi and Zoroastrian religion. But what connection have Mihr in Persia, Miiro in Kushan Bactria, and Mithras in the Roman Empire to one another?
Shenkar, Michael. 2015. “Images of Daēnā and Mithra on Two Seals from the Indo-Iranian Borderlands“, Studia Iranica 44(1), 99-117.
The article discusses two seals from the recently published collection of Aman Ur Rahman that depict previously unrecognized images of Iranian deities. It is suggested that the first seal, of eastern Sasanian manufacture, depicts a unique image of the Daēnā accompanied by two dogs. The second seal shows a well-known motif of a chariot of Mithra. The inscription connects it with the Pārata kings and helps to date the seal to the third-fourth centuries CE.
