Roman Breviary (17th century): St. Emerentiana, Jan 23, p.805: "A Roman virgin, step-sister of the blessed Agnes, while still a catechumen, burning with faith and charity, when she vehemently rebuked idol-worshippers who were stealing from Christians, was stoned and struck down by the crowd which she had angered. Praying in her agony at the tomb of holy Agnes, baptized by her own blood which she poured forth unflinchingly for Christ, she gave up her soul to God."
