Atterbury was made successively Dean of Carlisle and of Christ Church, and in 1713 succeeded Sprat as Dean of Westminster and Bishop of Rochester. Before making Swift's acquaintance he recommended his friend Trelawney, Bishop of Exeter, to read the _Tale of a Tub_, a book which is to be valued, 'in spite of its profaneness,' as 'an original in its kind, full of wit, humour, good sense, and learning.' Atterbury's taste for literature was not always so discriminative. He advised Pope, as has been already stated, to 'polish' _Samson Agonistes_, declared that all verses should have instruction at the bottom of them, and told the poet, as though he had discovered a merit, that his poetry was 'all over morality from the beginning to the end of it.' He ventured occasionally into the verse-making field himself, and wrote a song to Silvia, in which, after admitting that he had loved before as men worship strange deities, he adds: 'My heart, 'tis true, has often ranged, Like bees on gaudy flowers, And many a thousand loves has changed, Till it was fixed on yours. 'But, Silvia, when I saw those eyes, 'Twas soon determined there; Stars might as well forsake the skies, And vanish into air. 'When I from this great rule do err, New beauties to adore, May I again turn wanderer, And never settle more.' The close friendship between Atterbury and Pope did honour to both men, and when Pope went to London he would 'lie at the deanery.' There, unknown to his friend, the bishop carried on his Jacobite intrigues, and there may still be seen, in a residence made famous by more than one great name, a secret room in which Atterbury concealed his treasonable correspondence. The poet did not believe that his friend was guilty, but it has been well known since the publication of the Stuart papers, more than forty years ago, that the splendid defence made by Atterbury at his trial in the House of Lords was based upon a falsehood. For years the bishop appears to have corresponded, under feigned names and by the help of ciphers, with 'the king over the water;' but the plot which led to his imprisonment and ultimate exile was not discovered until 1722, when he was arrested for high treason. At his trial he called God to witness his innocence; and when Pope took leave of him in the Tower he told the poet he would allow him to call his sentence a just one if he should ever find that he had dealings with the Pretender in his exile. Pope gave evidence at his trial, and, as he told Spence, lost his self-possession and made two or three blunders. Atterbury was exiled in June, 1723. On reaching Calais he heard that Bolingbroke had just arrived there on his way to England, having had a royal pardon. 'Then I am exchanged,' he said.
