Mendaciarium

An collection of or conceptual room of falsehoods, lies, myths, misinformation, and confidently repeated errors.

Etymology
From Latin mendax mendac- “lying, deceitful, false,” source of English mendacity, + -arium, a suffix used for physical places, repositories, or enclosures.

By gathering so many commonly accepted fallacies into a single volume, Tom Burnam's The Dictionary of Misinformation serves as a meticulously cataloged mendaciarium, opening the door to a conceptual room filled with history's most confidently repeated errors.
