Isabel never recovered from the loss. After his death she burned many of her husband's papers, including journals and a planned new translation of "The Perfumed Garden" to be called "The Scented Garden", for which she had been offered six thousand guineas and which she regarded as his "magnum opus". She believed she was acting to protect her husband's reputation, and that she had been instructed to burn the manuscript of "The Scented Garden" by his spirit, but her actions were controversial. However, a substantial quantity of his written materials have survived, and are held by the Huntington Library in San Marino, California, including 21 boxes of his manuscripts, 24 boxes of correspondence, and other material (https://catalog.huntington.org/record=b1707757).
