She was the twin sister of St Benedict, patriarch of monasticism in the West (March 14), and his constant fellow-laborer in the vineyard of Christ. They lived in neighboring monasteries; though they loved one another dearly, they met only once a year, spending the day in prayer and spiritual conversation, then parting after sharing a simple meal. At their meeting in 543, she prevailed on her brother (and the monk who accompanied him) to break his own monastic rule and stay with her in vigil through the night. Three days later, as Benedict looked out his cell window, he saw his sister's soul in the form of a dove ascending to heaven.
