From the Golden Legend: There was a nun named Mary which was sick at Tripolin, in the monastery of Mary Magdalene, and was smitten in the thigh so grievously that five months during they doubted that she would have died, and then she bethought her and prayed thus in herself: Lord God, I am not worthy to pray to thee ne to be heard of thee, but I pray my lord, St. Dominic, that he be mediator between thee and me, that he may get to me the benefit of health.
And when she had long prayed in tears she slept, and saw St. Dominic with two friars, that opened the curtain that hung afore her bed, and entered and said to her: Wherefore desirest thou so sore to be healed?
And she said: Sir, that I might more devoutly serve God.
And then he drew out his ointment, which was of sweet odour, from under his cope and anointed her thigh, and she was anon all whole and said: This ointment is much precious, sweet and light.
And when she demanded how it was made, he said to her: This ointment is the ointment of love, and is so precious that it may not be bought for no price. For in the gifts of God is none better than love, for there is nothing more precious than charity, but it is soon lost if it be not well kept.
Then he appeared to her sister that night, that slept in the dortour, saying, “I have healed thy sister,” which anon arose and ran thither and found her whole. And when she felt her anointed with sensible unction she wiped it with great reverence with a bundle of silk.
And when she had told all this to the abbess, to her sister, and to her confessor, and had showed the unction and bundle, they were smitten with the novelty of the savour, so sweet-smelling that it might not be compared to none other aromatic, and they kept that unction with great reverence.
How agreeable the place is unto God where the body of St. Dominic resteth, howbeit that many miracles be showed there. Yet one shall I say to you here and that shall suffice.
