本文对新出土的契丹小字《耶律迪烈墓志铭》进行了考释，论证了墓主即是《辽史》卷９６有传的耶律迪烈。释读出了“北院承旨”、“上京留守”、“忠正军节度使”等一系列官名和十二生肖中的“猴”，并最终敲定了契丹小字中的“契丹”一词。 This paper examines the newly unearthed Khitan memoir, “Yeldidi Epitaph”, and demonstrates that the tomb owner is Yeldidi, a biography of Liao Dynasty. A series of official titles such as “Beiyuan Chengzu”, “Stay in Beijing” and “Zhongzhengjunjiedu” were read out and “Monkey” in the zodiac was read out. Finally, the word “Khitan” in Khitan small script was finalized.
