Of everything Zoroastrian priests committed to writing in the centuries after the fall of Sasanian Persia, none carries more weight than the Denkard — a vast ninth-century encyclopedia of the faith, gathering theology, law, history, and scriptural summary into nine books. It stands as the single most valuable source for understanding Zoroastrianism outside the Avesta itself, not least because it preserves, in summary and quotation, long passages of Avestan scripture that no longer survive in any other form.

The Denkard was not the work of one hand or one moment. Its first author was Ādurfarnbāg ī Farroxzādān, the highest-ranking leader of the orthodox Zoroastrian community in his time, and it reached its final form under the later editorship of Ādurbād Ēmēdān. Between them lies a work that functions less like a single composition and more like a priesthood's accumulated memory, set down before still more could be lost.

Historical Context

The Denkard's own survival is itself a story of loss as much as preservation. Books One and Two, along with the opening of Book Three, are gone entirely — no manuscript, however fragmentary, preserves them. This is why any reader encountering the Denkard in translation today begins, in effect, at Book Three: not an arbitrary starting point chosen by a translator, but the true edge of what remains.

What survives — Books Three through Nine — was brought into English through two distinct, independent translation efforts, separated by decades. The greater portion, Books Three through Seven, was translated by Dastur Peshotanji Behramji Sanjana, a prominent Zoroastrian head-priest, as part of a nineteen-volume edition presenting the Pahlavi text alongside Gujarati and English translations; Book Four within this project was translated by Ratanshah E. Kohiyar. Sanjana did not live to see the edition finished, and it was completed by his son, Darab Dastur Peshotan Sanjana, by 1928. Separately, Books Eight and Nine were translated by Edward William West and published in 1897 as Part IV of his Pahlavi Texts, within Max Müller's Sacred Books of the East — the same translation already represented on this Collection's page for West's work, meaning these two particular books of the Denkard can be read through either translation history.

Book Eight is of special significance to Zoroastrian textual history: it contains the Contents of the Nasks, a detailed summary of the Avesta's original twenty-one books, the majority of which are now lost entirely. In this sense, portions of the Denkard function as a kind of surviving table of contents for a scripture that time has otherwise taken away.
