The diary of Kosa Pan (Ok-phra Wisut Sunthon)

"This account from Kosa Pan's journal describes in great detail the arrival in Brest in 1686 of the first full Siamese embassy to reach France. The author is the first ambassador of that embassy, also known as the rachatbut Ok-phra Wisut Sunthon, who became phra khlang in 1688 under King Phetracha after the death of King Narai. This fragment is apparently all that survives of a massive report of the activities of the embassy written for King Narai.

It was accidentally discovered in Paris in the early 1980s, was published in Thai in 1984, and appears here in English for the first time."--BOOK JACKET.
