<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">ancient writing material</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for papyrus that I've seen before include "Kind of paper used in old Egyptian manuscripts" , "Egyptian material for writing on" , "Paper made from reeds" , "Egyptian writing matter" , "old document" .)
