Through the Keyhole

This image was taken in one of the many buildings you can explore within the ruins of Pompeii. I liked the way the light streamed in through the roof, and that unusual keyhole shaped entryway.

What did this image teach me?

I learned a lot about Pompeii whilst I was there, including this interesting fact: Due to their healthy diet (high in fruits and vegetables, low in sugars) the people of Pompeii had great teeth.
