This article studies Jean de Meun's reworking of the Pygmalion myth in his continuation of the Romance of the Rose. Through a close textual reading, we argue that Jean de Meun in his retelling of the myth mimetically interweaves Pygmalion's folly and the author's writing. Although earlier critical studies have recognized the figure of Pygmalion in the Rose as symbolizing the poet, they have generally overlooked how Pygmalion's folly operates on the level of authorship. We will argue that the Cypriot sculptor's 'foolish' transformation of matter (i.e. his statue of Galatea becoming real) is imitated in Jean's transformation of poetic matter into a tangible written artifact. Moreover, this artistic substantiation through madness stages authorial craft as a mimesis of divine power in order to confer to the author a quasi-demiurgic status of deus artifex.In a text as profoundly self-referential with respect to the craft of the medieval auctor as Jean de Meun's continuation of the Roman de la rose, the use of the Pygmalion myth (20787-21184), 1 not only the longest retelling of a myth in the combined Rose but moreover placed at the conclusion of the entire summa, is highly significant. Jean's version of the story is based on Ovid's Metamorphoses X: the legendary Cypriot king and sculptor Pygmalion stays celibate, but one day creates a statue of such beauty that he desperately falls in love with it. The goddess of love, Venus, rewards him by giving a soul to his creation. Pygmalion then happily marries this Galatea and begets Paphus. The fundamental value of the myth lies in its attempt to come to grips with the 'magical' moment of creation constituting the borderline between art and life, the mysterious substantiation, through artistic craft, of ideas conceived in the mind of the artist into palpable and living creations of art.
