The authorship of Niranam Grandhavari remains a matter of speculation. Some believe that it was written by
Mar Thoma VI himself. There was a legend that an uninterrupted chronicle was kept by the primates (Archdeacons) of Malankara Church until 1653, which Mar Thoma VI might have used as a reference. Niranam Grandhavari itself hints about such a Chronicle of the Archdeacons, saying that it was eaten by ants at
Niranam Church. However, the probability that Mar Thoma VI was the author is very low, considering that it is mentioned in some chapters that the author is writing it as per the order of Mar Thoma Metran. In addition to this, the nature of the text indicates that it was written by persons closely associated with Mar Thoma Metrans. ==Manuscripts and Transcriptions==
