Archaeological Discoveries and the Shape Evolution of Early Qin
The half-box qin found in the tomb of the Marquis of Haihun provides evidence that qin officially made in the Changyi Kingdom in Shandong in the middle and late Western Han Dynasty was also a half-box shape.In the early Eastern Han Dynasty,Huan Tan described a similar half-box shape qin in the New Treatise.Image data demonstrates that half-box qin could be traced back to the Three Kingdoms period.Studies from the perspective of organology show that there is a clear and exclusive inheritance and evolution relationship between ancient qin and the early half-box qin.Multiple pieces of evidence indicate that the qin described in the literature before the Eastern Han Dynasty was half-box shape,which along with its full-box descendants was the main type in the early history of the qin and the only predecessors of the hand-down qin.The existence of the so-called full-box central plain qin before the Eastern Han Dynasty is uncertain.Since the early Spring and Autumn Period,after a series of inheritance and evolution,the half-box qin had evolved into its full-box descendants in the middle and late Eastern Han Dynasty,resulting in two basic types known as the full-box narrow-tailed qin and full-box straight-sided qin,which were finalized as the present shape before the Eastern Jin Dynasty.
