Mine did and continues to be totally obsessed with Greek and Roman mythology. There are worse things. Particularly since I have no trouble piquing his interest with my classical architecture chatter. Cruising up CPW and he noticed that one of the buildings was sporting a decorative motif of what appeared to him to be Zeus and Hera. I couldn't really argue since he is the clear authority in our family. Nevertheless, I did. He ended up proving something when he noticed that right above the sculptural relief faces, there were shields and what looked to him to be obviously Spartan helmets.
I love that he's looking at buildings and finding things that that he connects to. Next question: why did the architect chose this theme for this building?
