Thanks to my colleagues with expertise in Asian materials, we believe we found half a dozen Chinese blocks or tiles with poems on one side and a carved image on the other side. The blocks were found broken into pieces but happily, have been reassembled. Each one has the same title, which loosely translates as “Poem(s) of the Emperor.” We have not yet found such a poem or series of poems. These are not printing blocks. Perhaps they were part of a poetry game?
