“Sir Berthold,” she said, “you disclose unheard-of mysteries. But it is not always an easy matter to distinguish truth from error. It would be painful to us to abandon our devotion to Diana. Nevertheless, let but a sign of the truth of your words appear to us, and we will believe in Jesus crucified.” But the younger sister said to the apostle— “My sister Oliveria has asked for a sign because she is of a prudent nature and full of wisdom. But if your God is the true God, Sir Berthold, would that I might know and love Him without being impelled by a sign.” The man of God understood by these words that Liberetta was born to become a great saint. And on this account he replied— “Sister Liberetta and Sister Oliveria, I have resolved to retire into that forest, there to lead the eremitical life which is both desirable and rare. I shall dwell in a hut of interlaced boughs, and support life upon roots. I shall pray unceasingly to God to change the hearts of the men of this country, and I shall bestow my benediction on the springs, so that the fairy folk may cease to come thither for the beguiling of sinners. Nevertheless, my sister Oliveria shall receive the sign for which she has asked. And a messenger sent by the Lord himself shall guide you both to my hermitage in order that I may instruct you in the faith of Jesus Christ.” Having spoken after this fashion, St. Berthold gave his blessing to the two sisters with the imposition of hands. After which he fared forth into the forest, from which he never afterwards emerged. CHAPTER III _How the unicorn came to the hall of Thierry, otherwise called Porphyrodimus, and conducted the two sisters Oliveria and Liberetta to the retreat of Messire St. Berthold, and of divers marvels that ensued._ Now one day, being alone in the kitchen, Oliveria was spinning wool beneath the chimney canopy when she saw approach her a beast of a perfect whiteness which had the body of a goat and the head of a horse, and which bore on its forehead a shining spear. Oliveria immediately recognized what animal it was, and as she had maintained her innocence she was not in the least afraid, being aware that the unicorn never does any harm to discreet maidens. And indeed the unicorn did but place his head gently upon Oliveria’s knees. Then turning again towards the door, by the direction of its eyes it invited the young girl to follow it without. Oliveria immediately called her sister, but when Liberetta entered the room the unicorn had disappeared; and so it came about that Liberetta, in accordance with her desire, acknowledged the true God without having been constrained by a sign.
