She was the friend of men of letters--this capricious great lady, and they have judged her best. To Swift in particular it was an attraction that she loved and befriended his favourite Gay. The earlier part of the brief correspondence from which the above quotation is borrowed, shows the Duchess in her most amiable light; and it was with Gay that it originated. From the days of her marriage she had protected and petted that fat and feckless fabulist; she had championed him in the matter of his second ballad-opera in such a way as to procure her own exile from Court; and at the time she began to write to Swift, Gay was domiciled at the Duke's country house at Ambresbury, or Amesbury, near Salisbury, in Wiltshire. Gay begins by sending Swift the Duchess's 'services,' and by wishing on his own account that Swift could come to England,--could come to Amesbury. Swift replies with conventional acknowledgment of the civility of the lady, whom he had not seen since she was a girl. He hears an ill thing of her, he says'--that she is _matre pulchrâ filia pulchrior_, and he would be angry she should excel her mother (Jane Leveson Gower), who, of old, had long been his 'principal goddess.' In the letter that succeeds, the Duchess herself adds a postscript to confirm Gay's invitation. 'I would fain have you come,' she writes. 'I can't say you'll be welcome; for I don't know you, and perhaps I shall not like you; but if I do not (unless you are a very vain person), you shall know my thoughts as soon as I do myself.' No mode of address could have suited Swift's humour better; and part of his next epistle to Gay replies to her challenge in the true Swiftian style. He begins very low down on the page--'as a mark of respect, like receiving her Grace at the bottom of the stairs.' He goes on with a protest for form's sake against the imperious manner of her advances; but he argues ingeniously that she must like him, since they are both unpopular with the Queen. If he comes, 'he will,' he adds, 'out of fear and prudence, appear as vain as he can, that he may not know her thoughts of him.' His closing sentences are in Malvolio's manner. 'This is your own direction, but it was needless. For Diogenes himself would be vain, to have received the honour of being one moment of his life in the thoughts of your grace.'
