The spread of Burmese language was accompanied by that of the Burmese script. The script was developed from either the Mon script or the Pyu script. Mainstream scholarship holds that the Burmese script was developed from the Mon script in 1058, a year after Anawrahta's conquest of the Thaton Kingdom. But recent research by Aung-Thwin argues that the Burmese script may instead have been derived from the Pyu script in the 10th century, and that the Burmese script was the parent of the "Burma Mon" script. He argues that the Mon script found in Burma was sufficiently different from the older Mon script found in the Mon homelands of Dvaravati or Haripunjaya (in present-day Thailand) with no archaeological evidence to prove any linkage between the two. On the other hand, Aung-Thwin continues, the latest archaeological evidence dates the Burmese script 58 to 109 years ahead of the Burma Mon script. The earliest "Burma Mon" script (at Prome) is dated to 1093 while the earliest Burmese script (the copper-gilt umbrella inscription of the Mahabodhi Temple) is dated to 1035. Indeed, if a "recast" 18th century copy of an original stone inscription is permissible as evidence, the Burmese script had already been in use at least since 984 AD.
