Analysis of information sources in references of the Wikipedia article "Majus" in English language version.
Most of our evidence for that later history comes from the Sasanian period (224–642 CE). In post-Sasanian Zoroastrian sources, the Pahlavi books, the word mogh (mgw), the Middle Persian descendant of Old Persian magu-, is hardly ever attested. Instead of this generic word, more specific titles are always given; where a generic word is necessary, the word mard, "man", is used.55 Since many reconstructions of Sasanian history are based on sources from later periods, the existence of the word in Sasanian Iran has sometimes been obscured. It is, however, not only frequently found in non-Iranian Sasanian sources (in Aramaic, Syriac and Greek), but it is also very well attested in the most reliable Iranian sources from the period itself, namely personal seals.56 In fact, the word mogh is a very common word on Sasanian seals and bullae. The word had a long and distinguished career in Islamic Persian poetry (pīr-e moghān etc),57 which shows that it had not disappeared from the common speech of the Persians. The question therefore arises why the Zoroastrians, who formulated their tradition in the 9th century, wanted to get rid of it, but so far no reasonable hypothesis has been suggested for this problem. The only suggestion one can think of that makes sense is the fact that the Aramaic word magūšā and the Arabic majūs were used not just to refer to Persian priests, but to Zoroastrians in general, and that the term came to be felt to be misleading for those who wanted to distinguish themselves as members of the priestly class.
