Answer
The artistic influence for Pauline Baynes's illustrations of "The Chronicles of Narnia" lies in the rich visual traditions of medieval manuscripts. These manuscripts, characterized by their intricate illuminations and vibrant colors, served as a source of inspiration for Baynes's depiction of Narnia's magical world. By drawing upon the aesthetics and techniques of medieval art, Baynes's illustrations successfully capture the enchantment and fantasy of C.S. Lewis's classic tale.
