"I have perused the last lampoon of your ingenious friend, and am not surprised you did not find me out under the name of Sappho, because there is nothing I ever heard in our characters or circumstances to make a parallel, but as the town (except you, who know better) generally suppose Pope means me, whenever he mentions that name, I cannot help taking notice of the horrible malice he bears against the lady signified by that name, which appears to be irritated by supposing her writer of the Verses to the Imitator of Horace. Now I can assure him they were wrote (without my knowledge) by a gentleman of great merit, whom I very much esteem, who he will never guess, and who, if he did know, he durst not attack; but I own the design was so well meant, and so excellently executed, that I cannot be sorry they were written. I wish you would advise poor Pope to turn to some more honest livelihood than libelling; I know he will allege in his excuse that he must write to eat, and he has now grown sensible that nobody will buy his verses except their curiosity is piqued to it, to see what is said of their acquaintance; but I think this method of gain so exceeding vile that it admits of no excuse at all.—Can anything be more detestable than his abusing poor Moore, scarce cold in his grave, when it is plain he kept back his poem, while he lived, for fear he should beat him for it? This is shocking to me, though of a man I never spoke to and hardly knew by sight; but I am seriously concerned at the worse scandal he has heaped on Mr. Congreve, who was my friend, and whom I am obliged to justify, because I can do it on my own knowledge, and, which is yet farther bring witness of it, from those who were then often with me that he was so far from loving Pope's rhyme, both that—and his conversation were perpetual jokes to him, exceeding despicable in his opinion, and he has often made us laugh in talking of them, being particularly pleasant on that subject. As to Pope's being born of honest parents, I verily believe it, and will add one praise to his mother's character, that (though I only knew her very old) she always appeared to me to have much better sense than himself. I desire, sir, as a favour, that you would show this letter to Pope, and you will very much oblige, sir,
"Your humble servant."
Lady Mary was not a person, after severe chastisement, to turn the other cheek, and Pope was well aware of it. He believed that more than one social satire upon him came from her pen; and he especially suspected her of having written, or anyhow of having had a hand in the composition of A Pop upon Pope, in which an account was given of a whipping in Ham Walk which was said to have been administered to him. The poet was so furious—he regarded it as an indirect attack on his physical deformity, of which he was always so conscious—that he actually inserted an announcement in the papers that no such incident had ever occurred— thereby drawing yet more attention to the lampoon. "You may be certain I shall never reply to such a libel as Lady Mary's," he wrote to Fortescue. "It is a pleasure and comfort at once to find out that with so much mind as so much malice must have to accuse or blacken my character, it can fix upon no one ill or immoral thing in my life and must content itself to say, my poetry is dull and my person ugly."
Lady Mary, in a letter to Arbuthnot, denied the authorship of A Pop upon Pope:
"Sir,
"Since I saw you I have made some inquiries, and heard more, of the story you was so kind to mention to me. I am told Pope has had the surprising impudence to assert he can bring the lampoon when he pleases to produce it, under my own hand; I desire he may be made to keep to this offer. If he is so skilful in counterfeiting hands, I suppose he will not confine that great talent to the gratifying his malice, but take some occasion to increase his fortune by the same method, and I may hope (by such practices) to see him exalted according to his merit, which nobody will rejoice at more than myself. I beg of you, sir (as an act of justice), to endeavour to set the truth in an open light, and then I leave to your judgment the character of those who have attempted to hurt mine in so barbarous a manner. I can assure you (in particular) you named a lady to me (as abused in this libel) whose name I never heard before, and as I never had any acquaintance with Dr. Swift am an utter stranger to all his affairs and even his person, which I never saw to my knowledge, and am now convinced the whole is a contrivance of Pope's to blast the reputation of one who never injured him. I am not more sensible of his injustice, than I am, sir, of your [sic] candour, generosity, and good sense I have found in you, which has obliged me to be with a very uncommon warmth your real friend, and I heartily wish for an opportunity of showing I am so more effectually than by subscribing myself your very
"Humble servant."
Whether, in spite of her denial, Lady Mary had a hand in A Pop upon Pope cannot be said; but it is certainly safe to believe that the following lines were written by her, in conjunction, the gossip of the day had it, with Lord Hervey, with some assistance from Mr. Wyndham, then tutor to the Duke of Cumberland:
