If you look carefully in the first panel, you can see some truly entertaining bad translation. It’s entirely possible that the author meant to refer to Alan Moore’s comic Promethea, but it’s more likely that they meant Prometheus. It’s even more likely that they meant to refer to the Ark of the Covenant – I’m not sure what the Arch of the Covenant is, exactly.
