I have been at Churches, Theatres, libraries, and picture galleries. The Cathedral is noble, the theatre grand, the library excellent, and the galleries I know nothing about—except as far as liking one picture out of a thousand. What has delighted me most is a manuscript collection (preserved in the Ambrosian library), of original love-letters and verses of Lucretia de Borgia & Cardinal Bembo; and a lock of her hair—so long—and fair & beautiful—and the letters so pretty & so loving that it makes one wretched not to have been born sooner to have at least seen her. And pray what do you think is one of her signatures?—why this ✣ a Cross—which she says “is to stand for her name &c.” Is not this amusing? I suppose you know that she was a famous beauty, & famous for the use she made of it; & that she was the love of this same Cardinal Bembo (besides a story about her papa Pope Alexander & her brother Caesar Borgia—which some people don’t believe—& others do), and that after all she ended with being Duchess of Ferrara, and an excellent mother & wife also; so good as to be quite an example. All this may or may not be, but the hair & the letters are so beautiful that I have done nothing but pore over them, & have made the librarian promise me a copy of some of them; and I mean to get some of the hair if I can. The verses are Spanish—the letters Italian—some signed—others with a cross—but all in her own hand-writing.
I am so hurried, & so sleepy, but so anxious to send you even a few lines my dearest Augusta, that you will forgive me troubling you so often; and I shall write again soon; but I have sent you so much lately, that you will have too many perhaps. A thousand, loves to you from me—which is very generous for I only ask one in return
