Episcopa Theodora is the Greek inscription on a 9th-century Christian mosaic in the Chapel of Bishop Zeno of Verona located within the Church of Saint Praxedis the Martyr in Rome.
The honorific title refers to the Lady Theodora, the historical mother of Pope Paschal I, who built the chapel for her while she was still alive, as indicated by the square halo of the mosaic.
[citation needed] Theodora was widely known to be a devout Christian in the Early Church, and was notable for her acts of virtue and Catholic piety.
[2][3][4] Catholic theologians and Roman art scholars take issue with this argument by pointing out that feminizations of clerical titles have traditionally been associated with the wives and widows of early Christian clergy since the Apostolic Age.
Therefore, the title Episcopa is said to have been used for the Lady Theodora for her esteemed position as the mother of the Pope as well as her own piety; a holy woman who practiced great austerity and religiosity, and not as an ordained bishop.
