Rituals and Offerings is a comic based on the lives of the ancient peoples, and their actual art is used as much as possible when creating this comic.
The Egyptians have a very rich artistic tradition, and so they get the most screen time, but I like to slip in the occasional Mesoamerican, Japanese, and Greek work in there as well.
All credit for the art goes to the original artists… most of whom died about 3000 years ago. The jokes, and the ideas behind them, however, are mine.
