Sasanian historiography is a problematic field, as almost all Middle Persian historical texts have disappeared, and even their Arabic translations are not extant, so we have to approach it based on two existing Middle Persian texts, references to lost Arabic translations, and the historical material preserved in Arabic and New Persian sources. The present chapter maps the extant material and gives an overview on what Sasanian historiography was. Additionally, the chapter provides an outline of the tension existing between local and universal history in the resulting reconstruction of Sasanian historiography. Sasanian historiography was strictly focused on Iran, but situated it in a broader Iranocentric ecumene, with the representation of human events taking place within a framework inspired by the Zoroastrian concept of ‘limited time’, during which good and evil fight against each other.
