Footnotes:
(1) The arched gateway (pratu chong kut) is an aperture in the wall large enough for someone to walk through. A surviving example stands at the southwest corner beside the premises of the Wat Rattana Chai, the former Wat Jin.
(2) Phraya Racha Wangsan is mentioned in the Royal Chronicles of Ayutthaya. The Phraya Racha Wangsan was the division chief of the Krom Asa Cham, responsible for the Cham communities in Ayutthaya (Chularatana, 2008). The author has the impression that the role of the Racha Wangsan should be understood more broadly, including being responsible for at least part of the Ayutthaya naval forces. The first French Embassy was lodged at the house of "a great Mandarin, a Persian by Nation". Hence, the author believes this was at the Phraya Racha Wangsan's house (Tachard, 1688).
