Much about this time he wrote (says the author of his Life) 'the renowned Hudibras; as he then had opportunities of conversing with the leaders of that party, whose religion he calls hypocrisy, whose politics rebellion, and whose speeches nonsense;' he was of an unshaken loyalty, though he was placed in the house of a rebel, and it is generally thought, that under the character of Hudibras, he intended to ridicule Sir Samuel Luke. After the restoration of Charles II. he was made secretary to the earl of Carbury, lord president of the principality of Wales, who appointed him steward of Ludlow Castle, when the court was revived there; and about this time he married one Mrs. Herbert, a gentlewoman of very good family. Anthony Wood says, she was a widow, and that Butler supported himself by her jointure; for though in his early years he had studied the common law, yet he had made no advantage by the practice of it; but others assert, that she was not a widow, and that though she had a competent fortune, it proved of little or no advantage to Butler, as most of it was unfortunately lost by being put out on bad security. Mr. Wood likewise says, that he was secretary to the duke of Buckingham, when that lord was chancellor of the university of Cambridge, and the life writer assures us he had a great kindness for him: but the late ingenious major Richardson Pack tells a story, which, if true, overthrows both their assertions, and as it is somewhat particular, we shall give it a place here. Mr. Wycherley had taken every opportunity to represent to his grace the duke of Buckingham, how well Mr. Butler had deserved of the Royal Family, by writing his inimitable Hudibras, and that it was a reproach to the court, that a person of his loyalty and wit should languish in obscurity, under so many wants. The duke seemed always to hearken to him with attention, and, after some time, undertook to recommend his pretentions to his Majesty. Mr. Wycherly, in hopes to keep him steady to his word, obtained of his Grace to name a day, when he might introduce that modest, unfortunate poet to his new patron; at last an appointment was made, Mr. Butler and his friend attended accordingly, the duke joined them. But, as the devil would have it (says the major) 'the door of the room, where he sat, was open, and his Grace, who had seated himself near it, observing a pimp of his acquaintance (the creature too was a knight) trip by with a brace of ladies, immediately quitted his engagement to follow another kind of business, at which he was more ready, than at doing good offices to men of desert, though no one was better qualified than he, both in regard to his fortune, and understanding to protect them, and from that hour to the day of his death, poor Butler never found the least effect of his promise, and descended to the grave oppressed with want and poverty.'
