Lastly, it is unclear if Diego de San Pedro was a "converso" (convert from Judaism to Christianity) or if he was not. It was common for those who converted to Christianity to use a saint's name as the family names. However, Whinnom points out that both old and new Christians followed this practice. San Pedro's professions as secretary to the Count of Urueña could also indicate that he was a Jewish converso, but there is no extant evidence of this fact. Several scholars point to the tone of some of San Pedro's works in support the theory, and maintain that "Cárcel del amor" is a literary response to the initiation of the Inquisition, but all this is mere speculation.
