In the Arthurian legends and later produced stories (like prince valiant), I have sometimes thought about how MBTI would apply to the characters in it.
King Arthur - eNFJ?
Mordred - ISTJ?
Sir Gawain - ESTP (i'm almost 100% sure!)
Sir Tristan - INFP?
Sir Lancelot - ENFP?
Come up with more and discuss, please What MBTI type does Galahad resemble most? Guinevere? Morgana le Fay?
As for by-stories such as Prince Valiant, I think Valiant himself is ENTP because of his ingenious tactical skills, leadership and excellent problem-solving skills.
Hit me with something and please don't let this subject die out
