# A chronicle of the <a href="https://en.wikipedia.org/wiki/Ayutthaya_Kingdom" class="extiw" title="w:Ayutthaya Kingdom">kingdom of Ayutthaya</a>, known by various names, including the <i>Royal Chronicle: Doctor Bradley Version</i> (after <a href="https://en.wikipedia.org/wiki/Dan_Beach_Bradley" class="extiw" title="w:Dan Beach Bradley">Dan Beach Bradley</a>, by whom the chronicle was first printed); the <i>Royal Chronicle: National Library Version</i>; the <i>Royal Chronicle: Two-Volume Version</i>; the <i>Royal Chronicle: Version by HRH Prince Paramanuchitchinorot</i>; and the <i>Royal Chronicle: Version by Somdet Phra Phonnarat of Wat Phra Chettuphon</i>.
<ol><li>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 <a href="https://en.wikipedia.org/wiki/th:%E0%B8%AA%E0%B8%A1%E0%B9%80%E0%B8%94%E0%B9%87%E0%B8%88%E0%B8%9E%E0%B8%A3%E0%B8%B0%E0%B8%9E%E0%B8%99%E0%B8%A3%E0%B8%B1%E0%B8%95%E0%B8%99%E0%B9%8C_%E0%B8%A7%E0%B8%B1%E0%B8%94%E0%B8%9E%E0%B8%A3%E0%B8%B0%E0%B9%80%E0%B8%8A%E0%B8%95%E0%B8%B8%E0%B8%9E%E0%B8%99" class="extiw" title="w:th:สมเด็จพระพนรัตน์ วัดพระเชตุพน">Somdet Phra Phonnarat</a>, abbot of <a href="https://en.wikipedia.org/wiki/Wat_Pho" class="extiw" title="w:Wat Pho">Wat Phra Chettuphon</a>, together with his pupil, HRH Prince <a href="https://en.wikipedia.org/wiki/Paramanuchitchinorot" class="extiw" title="w:Paramanuchitchinorot">Paramanuchitchinorot</a>. This means the present chronicle is a revision of the 1157 LE version, which is now known as the <i>Royal Chronicle: Phan Channumat (Choem) Version</i>. Academicians are also of the following opinion:
<ol><li>The revision must have been done in the reign of King <a href="https://en.wikipedia.org/wiki/Rama_I" class="extiw" title="w:Rama I">Rama I</a>, because Somdet Phra Phonnarat died in the following reign, the reign of King <a href="https://en.wikipedia.org/wiki/Rama_II" class="extiw" title="w:Rama II">Rama II</a>.</li>
<li>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).</li>
<li>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.</li></ol></li>
