Gog and Magog
While the confounding Gog and Magog as confined Jews was becoming commonplace, some, like Riccoldo or Vincent de Beauvais remained skeptics, and distinguished the Lost Tribes from Gog and Magog. As noted, Riccoldo had reported a Mongol folk-tradition that they were descended from Gog and Magog. He also addressed many minds (Westerners or otherwise) being credulous of the notion that Mongols might be Captive Jews, but after weighing the pros and cons, he concluded this was an open question.
