Demigods generally try to avoid museums. Not because they hate art, but rather because the would prefer to NOT see their godly parent naked, seducing some one, or both. Percy tries to avoid fountains in Europe, as there are many statues of Poseidon naked there. However, when they DO go to museums, they like to play a game called "Is that my godly parent or yours leaning seductively against something." It's usually Apollo, Hermes or Dionysus. Rachel and Piper have a hard time explaining to their parents why they do NOT want to go into a Greek museum. actually, all demigods who's mortal parents don't know they are demigods have a hard time explaining that. It's probably weirder then Sadie and Carter Kane seeing Osiris on a wall.
