Hymn 11 is devoted to Hippolytus, martyr of Rome buried on the Via Tiburtina (the martyrium of Hippolytus has been excavated, see Bertonière 1985, Guarducci 1977). Prudentius develops the legend given by Damasus (epigram 35 ) about a Novatianist presbyter Hippolytus (third century) who persuades his congregation to convert to the "proper" Church. The hagiographical dossier of saint Hippolytus is very complicated and it is impossible to say "whether he is one person or an amalgamation of two or more" (Malamud 1989:80-81). We cannot say whether he should be identified with Hippolytus of Rome, author of the Refutation of all Heresies or the presbyter Hippolytus exiled together with Bishop Pontianus of Rome (the same person?). If so, Damasus’s and Prudentius’s information about his adherence to the Novatianist schism must be wrong (on chronological grounds, since Hippolytus of Rome died in 235 and the Novatian schism started in 251). For a detailed approach to the "Hippolytan question" see Brent 1995 (especially pp. 369-388), Cerrato 2002.
