Legend dictates that Anus language was given to the Phlegms by Janus, their most high exalted deity. While it is common for prophets to receive hallucinations on mountains, this divine afflatus was issued at the peak of a butte. This is particularly significant because buttes are not commonplace in such a low-lying place known for its dikes. The one true prophet of the Phlegm people is known as Urbanus van Anus. He inscribed the analects which are received as the correct scripture of the Anus religion. These analects date to 69 BC and are the first known instance of written Anus.
