The Ramkhamhaeng inscription, also known as inscription #1. King Ramkhamhaeng is widely credited with the invention of the Thai alphabet, and this is the earliest known inscription using these letters, believed to date from 1292 CE. The inscription itself mentions that there was no Thai writing before this date.However, doubt has been cast on the inscription’s authenticity. It certainly demonstrates idiosyncrasies that are not apparent in other inscriptions of that era or later, such as the alphabetic nature of the script (vowels are represented not by diacritic marks as in modern Thai, but by inline vowel letters).At any rate, it would be short-sighted not to pay credit to the role of Brahmi-derived Pallava, Mon and Old Khmer in the formation of the proto-Thai alphabet.
