Бань Гу
The book is part of four early historiographies of the Twenty-Four Histories canon, together with the "Records of the Grand Historian", "Book of Han" and "Records of the Three Kingdoms". Fan Ye used earlier histories, including accounts by Sima Qian and Ban Gu, along with many others (some had similar names, such as the "Han Records of the Eastern Lodge" by various contemporaries throughout the 2nd century, and the "Records of Later Han" by Yuan Hong from the 4th century), most of which did not survive intact.
