- The recto of the frontispiece illustration of a youth, which was the end of the first half of the Shahnama, is a colophon containing the date 2 Ẕuʾl-Qaʿda 1058/18 November 1648. This, undoubtedly, refers to the completion of the text to that juncture.
- An inscription on 2-172 contains the date Ramażān 1059/September 1649, which is the date that painting was completed.
- The inscription on 3-195 contains the date 20 Rabiʾ II 1060 / 22 April 1650, the date that painting was completed.
This manuscript has apparently been confused by some historians with other manuscripts of the Shahnama (ms.D and ms.E) which also have paintings signed by Moʿin. For further elaboration click here.
The most comprehensive study of this manuscript to date was first published by Sheila Canby in the Journal of the David Collection in 2010, where, among other accomplishments, brought to print for the first time the core volume and its 27 paintings, and united them with the dispersed leaves known previously. The original 2010 article, entitled An Illustrated Shahnameh of 1650: Isfahan in the Service of Yazd is reproduced on this site for download in PDF format. A digitized updated version of her article is linked herewith. Much of the information cited on this page was derived from Ms. Canby's work, and we herewith wish to acknowledge that fact, and express our gratitude for her collaboration in posting it on this website.
