In 1654 he wrote a panegyric on Oliver Cromwell, as he did a poem on his death in 1658. At the restoration he was treated with great civility by King Charles II, who always made him one of his party in his diversions at the duke of Buckingham's, and other places, and gave him a grant of the provostship of Eaton-College; tho' that grant proved of no effect. He sat in several Parliaments after the restoration, and wrote a panegyric upon his Majesty's return, which however, was thought to fall much short of that which he before had wrote on Cromwell. The King one day asked him in raillery, 'How is it Waller, that you wrote a better encomium on Cromwell than on me.' May it please your Majesty, answered the bard, with the most admirable fineness, 'Poets generally succeed best in fiction.' Mr. Waller continued in the full vigour of his genius to the end of his life; his natural vivacity bore up against his years, and made his company agreeable to the last; which appears from the following little story. King James II having ordered the earl of Sunderland to desire Mr. Waller to attend him one afternoon; when he came, the King carried him into his closet, and there asked him how he liked such a picture? 'Sir, says Mr. Waller, my eyes are dim, and I know not whose it is.' The King answered, 'It is the Princess of Orange;' and says Mr. Waller, 'she is like the greatest woman in the world.' 'Whom do you call so, said the King,' 'Queen Elizabeth, said he.' 'I wonder, Mr. Waller, replied the King, you should think so; but I must confess, she had a wise council;' and Sir, said Mr. Waller, 'did you ever know a Fool chuse a wise one.' Mr. Waller died of a dropsy October 21, 1687. Finding his distemper encrease, and having yielded all hopes of recovery, he ordered his son-in-law Dr. Peter Birch, to desire all his children to join with him, and give him the sacrament. He at the same time professed himself a believer in revealed religion with great earnestness, telling them, that he remembered when the duke of Buckingham, once talked profanely before King Charles, he told him, 'My lord, I am a great deal older than your grace, and I believe I have heard more arguments for atheism, than ever your grace did; but I have lived long enough to see, there was nothing in them, and so I hope will your grace.' It is said, that had Mr. Waller lived longer, he would have inclined to the revolution, which by the violent measures of James II. he could foresee would happen. He was interred in the church-yard of Beaconsfield, where a monument is erected to his memory, the inscriptions on it were written by Mr. Thomas Rymer.
