Gautier de Metz (flourished 13th century) was a French poet and priest who is usually credited with the authorship of a treatise about the universe, L’Image du monde (c. 1246; “The Mirror of the World”; also called Mappemonde), based on the medieval Latin text Imago mundi by Honorius Inclusus.
Gautier’s poem is one of several medieval “encyclopaedic” works that describes creation, geography, and astronomy with factual as well as imaginary passages. Monsters, treasures, and distant lands are discussed in the pseudoscientific poem, which was translated into many languages during the Middle Ages and was beautifully illustrated in many manuscripts.
