In Geoffrey of Monmouth's Historia regum Brittanniae, Merlin performs magic such as levitating the rocks of Stonehenge and shapeshifting Uther into Ygerna's husband's form.

• A. True
• B. Not mentioned
• C. False
• D. It is uncertain

Answer: (C)

In Geoffrey of Monmouth’s Historia regum Britanniae, Merlin appears as a powerful magician and counselor, but the exact feats described here are not presented as his actions in this text. The narrative does not record Merlin levitating the stones of Stonehenge, nor does it describe him explicitly shapeshifting Uther Pendragon into Igraine’s husband’s likeness within this work. Those magical episodes belong to later Arthurian legends and other sources, rather than Geoffrey’s chronicle. So the statement as stated isn’t accurate for this text, making the correct choice false.
