On Shabbetai Sevi--a near contemporary account

Here is an interesting account of Shabbetai Sevi by a French traveler named Jean Dumont, baron de Carlscroon (1667-1727). The letter was written from Izmir/ Smyrna in 1692 when he was traveling through the Middle East (the Levant). It was published in French and then in English translation in London in 1705 under the title A new voyage to the Levant: containing an account of the most remarkable curiosities ... with historical observations ... By the Sieur du Mont. Done into English ; and adorn'd with figures.. (Incidentally, on the very next page there is a nice bit of antisemitic stereotyping.
