I believe the answer is:
apollo
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">god of light</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 apollo that I've seen before include "handsome fellow" , "Handsome Greek god" , "Greek god (twin brother of Artemis)" , "London theatre" , "Handsome young man of Greek mythology" .)
