Richard Neslon Frye, the Aga Khan Professor of Iranian Studies Emeritus, who passed away on 27 March 2014, has unfortunately become the subject of a political row in Iran. It is good to remember him for what he was, a scholar with a unique and refreshing style and a sharp eye for methodology:
There is always the danger in Avestan studies of seizing upon a device or a theory as the key to the understanding of that enigmatic book to the exclusion of all contrary evidence (which is declared corrupt and untrustworthy), proclaiming that the true meaning of the Avesta lies in this key. Johannes Hertel is the shining example of a competent Indo-Iranian philologist who proposed his Feuerlehre as the key to the understanding of both the Avesta and the Vedas. His ubiquitous fire was not taken seriously by others but his linguistic skill in support of fire was impressive. Just as Th. Noeldeke said of Pahlavi, “In Pehlewi stumpfen wir alle”, so the Avesta may drive all who study it slightly mad.
Frye, Richard Nelson. 1960. Georges Dumézil and the translators of the Avesta. Numen 7(2). 161–171.
