The satire contains one of Pope's offensive allusions to Lady Mary, and the celebrated portrait drawn from two notable women, the Duchess of Buckingham and Sarah, Duchess of Marlborough, from the latter of whom the poet, at one time, despite his unquestionable love of independence, received £1,000. The story, like many another in the career of Pope, is wrapt in mystery. Pope took great pains with the Epistle _Of the Use of Riches_. It was altered from the original conception by the advice of Warburton, who cared more for the argument of a poem than for its poetry. The thought and purpose of the _Essay_ are defective, notwithstanding Warburton's effort to clear them, but these defects are of slight moment when compared with the brilliant passages with which the poem is studded. Among them is the famous description of the Duke of Buckingham's death-bed which should be compared with Dryden's equally famous lines on the same nobleman's character. 'In the worst inn's worst room, with mat half-hung, The floors of plaster, and the walls of dung, On once a flock-heel, but repaired with straw, With tape-tied curtains never meant to draw, The George and Garter dangling from that bed Where tawdry yellow strove with dirty red, Great Villiers lies--alas! how changed from him, That life of pleasure, and that soul of whim! Gallant and gay, in Cliveden's proud alcove, The bower of wanton Shrewsbury and love; Or just as gay at council, in a ring Of mimic statesmen and their merry King. No wit to flatter left of all his store! No fool to laugh at, which he valued more. There, victor of his health, of fortune, friends, And fame, this lord of useless thousands ends.' There is also a covert attack in this Epistle upon the moneyed interest represented by Walpole, and on the political corruption which he sanctioned and promoted. Yet Pope knew how to praise the great Whig statesman for his social qualities: 'Seen him I have, but in his happier hour Of social pleasure, ill exchanged for power; Seen him uncumbered with the venal tribe, Smile without art and win without a bribe.'
