English: # A chronicle of the kingdom of Ayutthaya, known by various names, including the Royal Chronicle: Doctor Bradley Version (after Dan Beach Bradley, by whom the chronicle was first printed); the Royal Chronicle: National Library Version; the Royal Chronicle: Two-Volume Version; the Royal Chronicle: Version by HRH Prince Paramanuchitchinorot; and the Royal Chronicle: Version by Somdet Phra Phonnarat of Wat Phra Chettuphon.
The preamble of the manuscript states that there was a revision of a royal chronicle in the year 1157 Lesser Era (2338 Buddhist Era, 1795/96 Common Era) and the revision was again revised by Somdet Phra Phonnarat, abbot of Wat Phra Chettuphon, together with his pupil, HRH Prince Paramanuchitchinorot. This means the present chronicle is a revision of the 1157 LE version, which is now known as the Royal Chronicle: Phan Channumat (Choem) Version. Academicians are also of the following opinion:
The revision must have been done in the reign of King Rama I, because Somdet Phra Phonnarat died in the following reign, the reign of King Rama II.
Because (1) the contents of this version end in the year 1154 LE (2335 BE, 1792/93 CE) and (2) this version is a revision of the version of 1157 LE (2338 BE, 1795/96 CE), the revision process was possibly started around 2340 BE (1797/98 CE).
In the year 2340 BE (1797/98 CE), Prince Paramanuchitchinorot was just 7 years of age. Somdet Phra Phonnarat should be the sole person carrying out the revision.
