In accord with an ancient custom, this martyr is commemorated in the Catholic Church at the second Mass on Christmas Day and her name was included in the Roman Canon of the Mass in the fifth century. However, nothing is known about her history. She may have been martyred during the persecution of Diocletian at Sirmium in Pannonia, a Roman province in Central Europe where her cult originated. In a later legend, she was a Roman matron who associated with St. Chrysogonus and helped the Christian community at Aquileia.
