<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">ship that carried the golden fleece</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for argo that I've seen before include "Ship in which Jason searched for the Golden Fleece" , "Ship Jason sailed to find the Golden Fleece" , "Constellation; ship" , "Jason's boat" , "Name of ship sailed by Jason in search of the Golden Fleece" .)
