I believe the answer is:
clio
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">the muse of history</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 clio that I've seen before include "Muse of history (from Renault?)" , "one of nine sisters" , "1 across's Muse - from Renault?" , "one historically inspiring" , "Muse of history - car" .)
