Stewart, the source of the 1922 publication, whose title he transliterated as Mun Yazawin, was a 19th-century compilation (and translation into Burmese) of older Mon language manuscripts by one U Shwe Naw.
[note 1] Stewart continued that the reference Mon manuscripts were actually those collected by Sir Arthur Purves Phayre from Siam; and that Shwe Naw's Burmese language manuscript was found at the Mingun Pitaka Taik (Mingun Library) at Sagaing.
[2] According to Michael Aung-Thwin who followed up on Stewart's statement, the only Mon language history manuscript found in the Sir Arthur Phayre Collection in the British Library is a palm-leaf manuscript, cataloged as History of the Talaings.
[note 2] Furthermore, the epilogue section of the 1922 publication states that the manuscript—presumably the Mon language manuscript Phayre collected—was completed on the 6th waning of Tabodwe 1146 ME (30 January 1785).
