To the Duke and Duchess of Lorraine That is, Simon and Adelaide, not Gertrude, as most write. For the account of the conversion of this Duchess by, S. Bernard see Life, Bk. i. c. 14. She took the veil of a Religious in the Nunnery of Tart, in the environs of Dijon, as is clear from the autograph Letters of her son, Duke Matthew, who calls his mother Atheleïde. These Letters P. F. Chifflet refers to at the end of his four Opuscula, ed. Paris, 1679. I do not refer to the pretended Letters of Gertrude to Bernard, and Bernard to Gertrude, translated by Bernard Brito, from French into Portuguese and thence into Latin.
