Liu Ke was famous contemporary classical scholar of the Mid-T'ang, as well as one of the many writers of the Ling Nan school of the T'ang. Of his numberous writings, today only the Ox and Lamb Calendar, one volume of writings, and two poems have survived, most of the rest having long since disappeared. His background was fairly unusual, and as he was not mentioned in the T'ang Shu, biographical information is drawn from the writings of various contemporaries and several T'ang and Sung books. This information has never been seriously evaluated and put in order. In accordance with information past and present, this essay performs a general analysis that aims to flesh out important traces of this man of a thousand years ago.
