本文主要结合文献以及文物材料考察了“骨朵”形制演变及其得名缘由。通过出土实物指出了其形制演变过程为:石球→石器→铜殳→骨朵,并根据其首部形状,将“骨朵”分为蒺藜类、蒜头类、沙袋类三种。“骨朵”最早用作锤击类兵器,在辽代还用作刑具。金代以后,实用功能渐退,多用作卤薄仪仗类器具,或作为某种身份地位的标志。“骨朵”一词,来源于少数民族,而且很可能是匈奴语词的音译。 This paper mainly studies the evolution of “Boduo” shape and the reason of its origin in combination with the literature and cultural relics. The unearthed material shows that the evolution of its shape is: stone ball → stone → copper 殳 → bone flower, and according to its first shape, the “bone flower” is divided into three kinds of tribulosa, garlic, sandbags. “Bone Duo ” was first used as a hammering weapon, also used as a torture instrument in the Liao Dynasty. After the Jin Dynasty, practical functions gradually receded, and were mostly used as instruments of honor or honor ceremonies or as a sign of status. The word “bodhisattva” originates from the ethnic minorities and is most likely the transliteration of the wording of the Hsiungnu.
