锥形器是良渚文化时期一种以形状命名的玉器,它的上端首尖如锥,下端略阔,常做出短小的圆榫,榫上往往有横向的孔眼,但有长短粗细的区别。习惯上,我们只是将整体细长的称为锥形器,而将形体较粗短的称为玉坠。关于锥形器的功用,研究的学者已经不少。最早的是清末的吴大澂,他在《古玉图考》中收录了4件玉瑱、2件玉漆书笔。从器形看,都跟良渚文化锥形器接近(图一)。但从考古发掘情况看,吴大澂的考证显然跟实物相去太远。牟永抗先生认为集束出土于头端的锥形器是墓主冠饰的一个组成部分。林巳奈夫认为锥形器是“插在头上使用的簪子的一个组成部分”。林华东认为锥形器中的一 Taper Liangzhu period is a kind of shape named jade, its top tip as a cone, the lower end slightly larger, often make a short round tenon, tenon tend to have lateral holes, but the difference between the length and the thickness . Traditionally, we only called the overall slender tapered, while the body is shorter and thick called jade pendant. On the function of the taper, many scholars have studied. The earliest is the late Qing Wu Dao, he in the “ancient jade map test” contains 4 pieces of jade, 2 pieces of jade paint pen. See from the shape, with Liangzhu culture taper close (Figure 1). However, judging from the situation of archeological excavations, Wu Da-kong’s research apparently went too far with the real ones. Mr. Mou Yongkang believes that the tundish unearthed from the head end is an integral part of the crown tomb decoration. Linbanaidov believed that the taper was “an integral part of the hairpin used in the head.” Lin Huadong that one of the cones
