Apollo in his Chariot
This 17th-century king named his throne room "the Apollo room".
I thought it was pretty obviously Louis XIV (aka the Sun King), but the (now ex-)champ came up with Henry VIII. Regardless, it's a perfectly typical Jeopardy! question: asked "what did Louis XIV call his throne room?" and most people (including me) would draw a total blank.
Perhaps even if you'd been there and looked up at this - one among many works of art gracing Versailles.
