Which artifact is an illustrated manuscript written in an unknown language and sometimes considered a hoax?

• A. Rohonc Codex
• B. Voynich Manuscript
• C. Beale Manuscript
• D. Codex Seraphinianus

Answer: (A)

The element being tested is recognizing an illustrated manuscript whose script remains undeciphered and whose origin is debated, sometimes even labeled a hoax. The Rohonc Codex fits this description: it’s an old, heavily illustrated book whose text uses a script that hasn’t been reliably deciphered, and its origins are disputed, with some scholars calling it a forgery or hoax while others treat it as a genuine, enigmatic artifact. The Voynich Manuscript also appears undeciphered, but it’s not commonly described as a hoax; the Beale Manuscripts are cipher texts about hidden treasure rather than an illustrated language, and the Codex Seraphinianus is a modern art book with an invented language, not an ancient unknown-language manuscript.
