The Romans did some remarkable things - like the roads and aqueducts, but at some point they simply stopped inventing things and progressing and became distracted by sodomy which apparently came to fill their daily lives.
They didn't invent cameras or had any smart phones to take selfies - so they did the next best thing, they painted murals on their walls. My guess is that sodomy was so rampant that no one had any trouble getting confirmed to any Roman supreme court.
God's warning at Vesuvius thankfully preserved all this as a warning to future generations (as if the warning of Sodom and Gomorrah in the Old Testament wasn't enough).
