Asian and African studies blog Among the literary treasures of Thailand is the famous work Chindamani, "Jewels of Thought". The oldest version of this work is attributed to the seventeenth-century monk and court astrologer Horathibodi of Ayutthaya. It is thought that he compiled it around 1670 in Lopburi for King Narai, but he may have drawn inspiration and knowledge from older texts. Although the original work has not been preserved physically, copies of it are held in numerous archives and libraries in Thailand and abroad. Chindamani is a treatise about "writing", covering vocabulary, orthography, grammar, loan words from Pali, Sanskrit and Khmer, literary styles and poetry conventions.
