Origins

Probably via Ancient Greek Μίθρας (Míthras) from some unattested Old Iranian intermediary, ultimately from vocative Avestan 𐬨𐬌𐬚𐬭𐬀 (miθra) (cf. Mithra). Until the 1970s, the character of Roman Mithras was widely assumed to be a continuation of that of Iranian Mithra (and thus also of Indo-Iranian *mitra). This notion is no longer followed today, and it is generally agreed that borrowing (e.g. of the name) does not constitute continuation.
