De viris illustribus
Quiricus, the dedicatee of Ildefonsus' "De perpetua virginitate", succeeded him as bishop. His later successor, Julian, included Ildefonsus among the biographies added in his own continuation to the "De viris illustribus". Another successor, Cixila, wrote a hagiographical life of Ildefonsus. During the 13th century, the Dominican Rodrigo de Cerrato included Ildefonsus among his vignettes of illustrious men.
