However, I want to focus on a particular type of fresco. These were buried by Mt. Vesuvius in 79 CE when it erupted, after decimating Pompeii and Herculaneum, along with everything and everyone around it like a holocaust of hellfire. They've since been discovered in the 18th century, and are made by painting upon wet plaster. Though the technique used is lost, as these frescoes are even better preserved than any we make today.
Pompeii itself was a vibrant city which was something of a merchant town. One of its specialties involved frescoes which depicted goods and services, especially those which were raw and pornographic, indicating the highest quality of service one could ever hope for.
What's the point? Enjoy the frescoes and triforce. Peace.
