Which of the following is known for having an unknown author and undeciphered illustrations?

• A. Voynich Manuscript
• B. Rongorongo
• C. Toynbee Tiles
• D. Kryptos

Answer: (A)

The main idea here is recognizing a work that is famous for both an unknown author and text that hasn’t been deciphered, with illustrations that add to the mystery. The Voynich Manuscript fits this perfectly: it’s a medieval codex filled with odd, unfamiliar plant drawings, astronomical and cosmological diagrams, and other enigmatic scenes, all accompanied by a writing system that has never been cracked. No author has been reliably identified for the manuscript, and the language runs with patterns that cryptographers have tried for centuries without reaching a consensus. That combination of an unidentified writer and an unreadable script, paired with the striking, puzzling illustrations, makes it the quintessential example.

Rongorongo is another enigmatic undeciphered script, but it’s primarily discussed in terms of a writing system rather than a single illustrated codex with a claimed, unknown author. Kryptos has a known author and only portions remain unsolved, while Toynbee Tiles are a modern hoax rather than a historical manuscript with undeciphered text and illustrations.
