The claims—shocking for the implication that most of Thai history would have to be rewritten—led to intense, often heated, scholarly debate, joined by dozens of academics both making rebuttals as well as giving support. and a compilation of English-language articles published in 1991 by the

scanning electron microscopy and
energy-dispersive X-ray spectroscopy found the Ram Khamhaeng stele to be the same age (700–500 years) as four other Sukhothai inscriptions, several proponents remain convinced of the forgery theory, and the debate has not been definitively settled.
