Qazvini Collates the Manuscripts and Persian Textual Criticism Gets Its Method

Persian textual criticism reconstructs the most reliable text of classical Persian works from their surviving manuscripts, establishing which variant reading of a disputed passage is most likely original rather than reprinting whichever copy happened to be most accessible. The Iranian scholar Mohammad Qazvini produced the field's founding critical edition, Nezami Aruzi's twelfth century Chahar Maqale, for the Gibb Memorial Series, dating his preface to 14 January 1910 and integrating European philological collation technique with the Arabic and Persian manuscript tradition's own editorial conventions to weigh variant readings systematically rather than by guesswork.

Qazvini's method, comparing every available manuscript witness against the others and giving explicit reasons for preferring one reading over another, set the editorial standard later Persian critical editions have followed. A classical Persian religious or Sufi text is frequently transmitted through manuscripts that disagree with each other in real and consequential ways, and Persian textual criticism is what the atlas relies on to establish which reading of a disputed line a scholarly edition actually supports, distinct from a popular printed text that silently follows one manuscript without explaining the choice.
