Mithra(Avestan: Miθpa) is the Zoroastrian divinity (yazata) of covenant and oath. In addition to being the divinity of contracts, Mithra is also a judicial figure, an all-seeing protector of Truth, and the guardian of cattle, the harvest and of The Waters.
The term Mithra is from the Avestan language. In Middle Iranian languages (Middle Persian, Parthian etc.), Mithra became Mehr, Myhr etc., from which Modern Persian مهر Mehr, Pashto لمر Lmar, Waziri ميېر Myer and Armenian Mihr/Mher ultimately derive.
The Romans attributed their Mithraic Mysteries to Persian or Zoroastrian sources relating to Mithra. However, since the early 1970s the dominant scholarship has noted dissimilarities, and those mysteries are now qualified as a distinct Roman product.
