The deck utilizes sophisticated 15th-century cryptographic techniques, including "Sigla"—a Roman shorthand using the first and last letters of words.

A 19th-century exploration of a cavern in Adams County, Ohio, revealed a tomb containing the mummies of nine-foot-tall men. The central mausoleum featured a life-sized statue of a man with "Israelite-ish" features and a book made of 100 thin copper leaves engraved with Hebrew-like characters. The mummies were reportedly wrapped in cloth coated with an aromatic varnish, similar to Egyptian preservation techniques.
