Marcela Londoño holds a PhD in Literary Theory and Comparative Literature and a degree in Spanish Philology from the Universitat Autònoma de Barcelona, where she is currently a Marie Skłodowska-Curie researcher. She has carried out research stays in Lisbon (Calouste Gulbenkian Foundation for foreign researchers) and has taught Spanish language and literature at the ENS-LSH in Lyon. Her main line of research is the control of private piety in Spain, Italy and Portugal (1500-1800), with particular attention to deviant or superstitious devotional practices, principally those in which the text was the central element, and has published a book on the subject Las oraciones censuradas. Superstición y devoción en los índices de libros prohibidos de España y Portugal (1551-1583) (Barcelona: Herder, 2019). She is currently developing the project Forbidden Prayers Library: Shaping Private Piety in Counter-Reformation Europe (16th-18th centuries). This project covers the study of the corpus of prayers and other objects, midway between piety and superstition, which were included in catalogues and other documents of censorship in an attempt to eradicate their use.
