Oruch charges that the traditions associated with "Valentine's Day", documented in Geoffrey Chaucer's "Parlement of Foules" and set in the fictional context of an old tradition, did not exist before Chaucer. He argues that the speculative explanation of sentimental customs, posing as historical fact, had their origins among 18th-century antiquaries, notably Alban Butler, the author of "Butler's Lives of Saints", and have been perpetuated even by respectable modern scholars. In the French 14th-century manuscript illumination from a "Vies des Saints" ("illustration above"), Saint Valentine, bishop of Terni, oversees the construction of his basilica at Terni; there is no suggestion here that the bishop was a patron of lovers.
