This article addresses the issue of Avestan (Av.)/Middle Persian (MP) tense mismatches that are occasionally found in the Zand, the MP translation with commentary of the Avesta. While most of these mismatches turn out to be aspectually insignificant or illusory once examined more closely, some of them appear to illustrate the use of the MP preterite as a temporally unspecified perfective category, contrasting with its usual perception as a simple past. In accordance with a pattern found also in non-translational MP literature, the perfective usage of the preterite is argued to be present in the translation of a series of Av. performative utterances in Visperad 3 (the “installation of the Av. priestly college”). Moreover, its use can be observed when the Zand depicts two punctual events as temporally coinciding within a timeless (gnomic) statement. Proceeding from these observations, I discuss the expression of performativity in MP on a more general level. The observations shared in this article support the view that, if considered diligently, the older Zand texts have the potential to contribute valuable data to the linguistic description of MP. Conversely, the article shows how paying close attention to the MP translators’ use of verbal forms may inform our interpretation of the Zand.
