Phra Ruang

It is also found as a title that may have referred to one or more kings of Sukhothai, and is referred to in the title of many works of literature, including the Trai Phum Phra Ruang, a Sukhothai-era religious text describing the Buddhist cosmology.

A common version of the Phra Ruang legend is that he was a Thai chieftain of Lavo (Lopburi) with supernatural powers of speech.

When the Khom king wanted him dead, Phra Ruang escaped and ordained as a monk at Sukhothai.

A Khom spy, "diving underground", was sent to find him, but not knowing Phra Ruang's face, inadvertently asked him when they met.

One of the best known is a 1917 play by King Vajiravudh (Rama VI), who explained the supernatural powers as acts of Phra Ruang's great wit.
