Many of the walls in Pompeii were painted with frescos. The city must have employed an army of artists, most of them with talent. I really enjoyed the one above.  I wanted to add little comic book bubbles above the heads of the two sitting figures:

Marcus: Maybe we should evacuate? Vesuvius is acting very angry this morning. 

Gaius: Nah. Forget Vesuvius. Let’s just sit by the beach, drink more wine, and watch this weird dude with a stick.  Carpe Diem.
