After this we entered into the country where the court of Ken-khan used to be held, which was formerly called the country of the Naymans, who were the peculiar subjects of Prester John. Though I did not see that court till my return, I shall briefly mention what befel his son and wives. Ken-khan being dead, Baatu desired that Mangu should be khan, but I could not learn exactly the manner of Ken-khan's death. Friar Andrew says he died of the effects of a medicine, which Baatu was suspected of having procured to be given him. I heard, on the other hand, that he summoned Baatu to do him homage, who accordingly began his journey with much external pomp, but with great inward apprehensions, sending forward his brother Stichin; who, when he came to Keu-khan, and ought to have presented him with the cup, high words arose between them, and they slew one another. The widow of Stichin kept us a whole day at her house, that we might pray for her and bless her. When Ken was dead, and Mangu chosen emperor by the consent of Baatu, which was when friar Andrew was there, Siremon, the brother of Ken, at the instigation of the wife and peculiar vassals of Ken, went with a great train, as if to do homage to Mangu, but with the intention of putting him and all his court to death. When within a few days journey of the court of Mangu, one of his waggons broke down, and a servant of Mangu happened to assist the waggoner in repairing it. This man was very inquisitive into the objects of the journey, and the waggoner revealed the whole plot to him. Pretending to make very light of the matter, he went privately and took a good horse from the herd, and rode with great speed with the intelligence to the court of Mangu; who quickly assembled his forces, and placing a strong guard around his court; sent the rest against Siremon, and brought him and all his followers prisoners to court. He confessed his intentions, and he and his eldest son, with 300 noble Tartars of their party, were put to death. The ladies were also sent for who were concerned in the plot, and being beaten with burning fire-brands till they confessed, were slain likewise. Kon, the youngest son of Siremon, who was incapable of entering into the conspiracy, from his youth, was permitted to enjoy the inheritance of his father; but our guide durst not enter the house either in going or returning.
