Faltonia Betitia Proba (fl. late 4th century) was a Roman poet, writer of a Christian cento (Lat. for patchwork), which circulated in the Eastern and Western Empire toward the end of the 4th century. The work consists of 694 verses culled from Virgil’s Eclogues, Georgics, and Aeneid, narrating episodes from Genesis, Exodus, and the four Gospels. The narrative sections are interspersed with proems, interludes, and epilogues pervaded by a confessional and devotional theme. The declared intention of the poet is to relate the “mysteries of Virgil” (arcana . . . vatis, v.12) and to show that Virgil “sang about the pious feats of Christ” (Vergilium cecinisse . . . pia munera Christi v. 23). This makes Proba one of the first Roman poets to have actively appropriated Virgil as a Christian prophet.There are over a hundred manuscripts containing Proba’s cento, the oldest of which date back to the 8th century, and a large number of early modern editions. Thanks to Giovanni Boccaccio’s De mulieribus claris (1374), Proba became important in the querelle des femmes as an example of an educated woman.
