辽代文献材料传世较少,《辽史》疏漏,遗留问题颇多,今天研究辽史需要大量的考古发现材料进行补充和完善。此铜印是近年出土的一件辽代重要铜官印,出土地点明确,且年代较早,职官少见,颇为珍贵,并可补《辽史·百官志》之缺失。 Liao Dynasty literature handed down less, “Liao history” omission, there are many legacy problems, today need to study a large number of Liao history of archeological discovery materials to supplement and improve. This bronze seal is an important bronze seal of the Liao Dynasty unearthed in recent years. The unearthed site was clear, with an earlier age, a rare and exquisite official position, and could make up for the lack of “History of the Liao, Baiguanzhi”.
