Epistle IV. pursues the same subject as the third, and deals mainly with false taste in the expenditure of wealth, and with the necessity of following 'sense, of every art the soul.' In this poem there is the far-famed description of Timon's Villa, and by Timon Pope was accused of representing the Duke of Chandos, whose estate at Canons he is supposed to have held in scorn after having been, as he acknowledges, 'distinguished' by its master. That would not have deterred Pope from producing a brilliant picture, and his equivocations did but serve to increase suspicion. Probably he found it convenient to use some features of what he may have seen at Canons while composing a general sketch with no special application. The _Moral Essays_, it may be added, are not especially moral, but they are full of fine things, and form a portion of Pope's verse second only to the _Imitations from Horace_. These _Imitations_ are introduced by the Prologue addressed to Dr. Arbuthnot, a poem of more than common brilliancy, and also more than commonly venomous. Nowhere, perhaps, is there in Pope's works so powerful and bitter an attack as the twenty-five lines in the Prologue devoted to the vivisection of Lord Hervey, which we are forced to admire while feeling their malevolence; nowhere is there a more consummate piece of satire than the twenty-two lines that contain the poet's masterpiece, the character of Atticus; and nowhere, I may add, are there lines more personally interesting. Portions of the poem were written long before the date of publication, and this is Pope's excuse, a rather lame one perhaps, for printing the character of Atticus and the lines on his mother after the death of Addison and of Mrs. Pope. 'When I had a fever one winter in town,' Pope said to his friend Spence, 'that confined me to my room for some days, Lord Bolingbroke came to see me, happened to take up a Horace that lay on the table, and in turning it over dipt on the first satire of the second book. He observed how well that would hit my case if I were to imitate it in English. After he was gone I read it over, translated it in a morning or two, and sent it to press in a week or fortnight after. And this was the occasion of my imitating some other of the satires and epistles afterwards.' Bolingbroke did his friend a better service in giving this advice than he had done with regard to the _Essay on Man_; and the six _Imitations_, with the Prologue and Epilogue, which are among the latest fruits of Pope's genius as a satirist, are also the ripest. Warburton, writing of the _Imitations of Horace_, says: 'Whoever expects a paraphrase of Horace or a faithful copy of his genius or his manner of writing in these _Imitations_ will be much disappointed. Our author uses the Roman poet for little more than his canvas; and if the old design or colouring chance to suit his purpose, it is well; if not, he employs his own without scruple or ceremony.'
