中文摘要 古璽中有部分「數字印」璽文,海內外學者或為矜慎,一直當做未能辨識的文字處理,「數字印」的觀念更未曾見璽印研究方家提出。本研究試從《古璽彙編》及其他坊間刊行相關譜錄中所載的幾方「數字印」,原書未釋或有些已經前賢考釋容有不同看法者,存在可再補充的地方,提出拙見並就正於方家;其中部分璽印文字參考學者精論,闡明自甲骨文、金文的相關文字演變,並參考貨幣文字,彙輯近年研究璽印心得合為十三則,以為或可增列「數字印」為一類,提供日後研究璽印文字的另一新方向。 Abstract The discreet attitudes toward some number seals among the ancient royal seals were taken by scholars around the world. The seal content is seen as unrecognized characters. The notion of “number seal” has not been proposed by any expert in the field of the ancient royal seals. I, therefore, edited 13 texts regarding this issue based on my researches in the ancient royal seals and references of currency characters, so that a new category of “number seal” can be innovated. I hope it can initiate a new perspective for researches in characters of the ancient royal seals.
