ラシードゥッディーン
The Altan Debter, "Golden Book" (Mongolian Cyrillic: Алтан дэвтэр , Mongolian script: ) is an early, now lost history of the Mongols. Rashid-al-Din Hamadani had access to it when writing his Chronicles, Jami al-Tawarikh. Some believe that "The Secret History of the Mongols" is based on it, though Morgan argues that the two sources, though in agreement on broad facts and events, are "clearly quite independent of each other."
