(Once this creature was at the church of Assisi, there she was shown our Ladyís headscarf which she herself wore here on earth, displayed with great attention and reverence. Than the creature was moved to great devotion; she wept, she sobbed, and she cried with plenteous tears and many holy thoughts. She was also present there on Lammas Day when the great pardon of plenary remission may be gained, so that I was able to obtain grace and mercy and forgiveness not only for herself but for all her friends and her enemies and the souls in Purgatory.)
And ther was a lady was comyn fro Rome to purchasyn hir pardon. Hir name was Margaret Florentyne and sche had wyth hir many Knygtys of Roodys, many gentylwomen, and mekyl good caryage.
