Book excerpt: Othea’s Letter to Hector, one of Christine de Pizan’s most popular works, is at the same time one of her most complex creations. Combining a somewhat Sibylline verse text based on a mythological figure with extensive citation of pagan sapiential authorities, the Bible, and the Church Fathers, it showcases Christine’s extraordinary learning and her innovative approach to didacticism. An appendix provides new insights on her skillful use of patristic sources and creative command of Latin authors.
