上图为云南楚雄万家坝古墓群出土的铜鼓,是最原始的铜鼓,为春秋晚期制品,制作较粗糙,出土时与作为炊具用的铜釜在一起。由于鼓面有烟痕,人们多认为铜鼓是由作为生活器皿的铜釜演变而成的。它们可能是鼓、釜兼用时期的遗物。 The picture above shows the bronze drum excavated from the ancient tombs of Wanjiaba, Chuxiong, Yunnan. It is the most primitive bronze drum, which is a product of the late Spring and Autumn Period that was made rough and unearthed together with a copper kettle used as a cookware. Due to the presence of smoke marks on the drumheads, it is often thought that copper drums have evolved from the copper vessels used as living vessels. They may be relics of the period of drums and kettles.
