金玉共振：中原青铜时代伊始玉兵器的演变态势

在中原青铜时代伊始的二里头时代，青铜礼兵器渗入并局部替代既有的玉礼器器种，形成“金玉共振”的局面。大型、片状、有刃，构成了二里头玉石质礼兵器的主旋律，这是对史前玉器的重大扬弃。当烈火铸就的贵金属——青铜被塑成温文尔雅的礼容器，温润可人的玉却隐隐地呈现出某种杀伐之气。“祀与戎”这两件“国之大事”，就这样被和谐地融入早期王朝的礼仪制度中。以有内钺、直内和曲内戈为代表的二里头文化青铜兵器，奠定了中国古代兵器的基本格局。其中，戈的出现意义尤其重大，啄击兼勾杀的威力使其极利于近战，成为日后中国冷兵器中的主宰器种。二里头都城中出土的玉石钺，和迄今所知中国最早的青铜钺，应是已出现的王权的一个重要象征。

Co--Resonance of Gold and Jade：Evolution Trend of Jade Weapon in the Beginning of the Bronze Age of the Central Plains

In the era of Erlitou,the beginning of the Bronze Age of the Central Plains,the ritual and arm bronze wares penetrated and they partly substituted jadewares. Thus the co--ex- istence of gold and jade came into being. Prehistoric jadeware features were discarded by the large,flak,edged ritual and weapon jadewares of Erlitou. When the precious metal--the bronze was cast to be ritual vessels,the warm and gentle jade was cast to be weapons with murderous took. Thus two pieces of＂affairs of state＇--＂worship and weapon＂were integrated into the early states~ ritual system in harmony. The Erlitou bronze weapons with their uniqueness laid the basic pattern of ancient Chinese weapons. And the appearance of dagger--axe was of great sig- nificance in that it became the dominating weapon type in later China＇s cold weapons. The un- earthed jade ax from Ertitou capital and the oldest ever--known Chinese bronze ax should be an important symbol of the emerged royal power.
