The legend of Theophilus is a widely disseminated medieval miracle story. A good man gives in to Vain Glory, sells his soul to the Devil, has a terrible crisis of conscience, and is saved by the Virgin. The story is translated into most European languages and appears in stained glass, sculpture, and manuscripts. Gautier de Coinci writes the longest version of the legend; its colourful details reveal the medieval period's deep fear of hell and the Devil and its high hopes in the Virgin and the Church.

Gautier de Coinci (1177–1236) was a French abbot and musical arranger, chiefly known for his devotion to the Virgin Mary.

This is the first English translation of Gautier de Coinci's pre-Faustian version of the legend of Theophilus.  It is presented in a facing-page translation with the original Old French, along with a full introduction and notes.
