The Iranian texts discovered at the beginning of the 20th-century during the German excavations of the Turfan oasis constitute a major source for modern scholarship on Manichaeism; like the Nag Hammadi Library, they provide an important corrective to the exclusively polemical accounts that had survived the manuscript transmission. The numerous textual fragments have been patiently published over the past century by a number of scholars, and this critical project is still ongoing.
The Turfanforschung group at the Berlin-Brandenburgische Akademie der Wissenschaften has published to the web the Digitales Turfan-Archiv, which includes a variety of literature from the Turfan oasis, including “Texte in Manichäischer Schrift,” in the Parthian and Middle Persian languages, as well as some in Old Turkic. This section contains high-resolution images of basically the entire run of texts in Manichaean script, more than 9,200 fragments, catalogued according to the more recent “M” categorization cited in contemporary scholarship (from Mary Boyce’s A Catalogue of the Iranian Manuscripts in Manichaean Script in the German Turfan Collection [Berlin, Akademie Verlag, 1960]); the glass plates show the former “T” categorization:
The Middle Persian and Parthian eTexts for many of these documents is available from TITUS at the University of Frankfurt:
