Heretofore three fragments of Maniʼs Living Gospel – the most important work of Mani – have been recognized in Middle Persian and in Manichaean script: M17, M172/I/ and M644. This article, with a codicological and textological approach, shows that M17 and the new fragment M5439 are two separate pieces of a single manuscript page. The verso-side of M5439 has a new text. Now, after the identification and reading of this damaged fragment, we are able to correct the previous reconstructions and comment on a few Middle Persian words. The text contains a part of the exordium and of the chapter Aleph of the Living Gospel.
