Nicolas Gervaise (ca.1662-1729 CE), a young French theological student of the “Société des Missions Etrangères” residing in Ayutthaya in the late 17th century, wrote in his work on Ayutthaya [2]: "The second office is that of the captain of the king’s bodyguard, known as the oya rytcho. Its functions are not comparable to those of the office with the same name in France. The captain’s duties do not demand that he follow the king everywhere nor always remain at his side. He is, in reality, the first official of the Royal Household and in this capacity, he takes precedence over all others at court."

(1) Khlong Ayothya, and in its extension, Khlong Kudi Dao, was an artificial short-cut canal running north-south and dug in a loop of the Pa Sak River, which riverbed later became Khlong Hantra. The canal is defunct today, but some small stretches can still be seen parallel with Road No 3058.
(2) The name Palelai is derived from the Pāli word Pārileyyaka. The Buddha went into retreat in the Pārileyyaka Forest in search of solitude after the monks in Kosambi did not take his advice in settling a quarrel among themselves. Kosambi (Pali) or Kaushambi (Sanskrit) was the capital of the Vatsa Kingdom of Uttarapatha, one of the sixteen mahajanapadas in ancient India
