This is a tenth century play composed by the Frankish nun, Hrotsvitha of Gandersheim. It entails the conversion of the courtesan Tha s. The holy monk Paphnutius, following the example of Abraham, goes to find Tha s under the guise of a lover. He converted her and imposed as penance on her the need to remain confined in a narrow cell for five years. Tha s by this just expiation is reconciled to the Lord. Fifteen days after having completed her penance, she fell asleep in the bosom of Christ.
