The Shizhoupian (Chinese: 史籀篇) is the first known Chinese dictionary, and was written in the ancient Large seal script. The work was traditionally dated to the reign of King Xuan of Zhou (827–782 BCE), but many modern scholars assign it to the state of Qin in the Warring States period (c. 475 – 221 BCE). The text is no longer fully extant, and it is now known only through fragments.
