The significance of this rare bronze object is an enigma, but It has clearly been preserved as a scholar's object. It is possible that it is of ritual significance, and is possibly emblematic of Mount Tai, with its acute triangular form, natural contours and irregularities, combined with the motif of a sun.

Mount Tai is the foremost of the five sacred mountains of China, associated with sunrise, birth, and renewal. It has been venerated and worshipped since at least the Shang dynasty, one of the principal places where the emperor would pay homage to heaven (on the summit) and earth (at the foot of the mountain).
