They were very industrious to find some charge against Oxford; and asked Prior, with great earnestness, who was present when the preliminary articles were talked of or signed at his house? He told them, that either the earl of Oxford or the duke of Shrewsbury was absent, but he could not remember which; an answer which perplexed them, because it supplied no accusation against either. "Could any thing be more absurd," says he, "or more inhuman, than to propose to me a question, by the answering of which I might, according to them, prove myself a traitor? And notwithstanding their solemn promise, that nothing which I could say should hurt myself, I had no reason to trust them; for they violated that promise about five hours after. However, I owned I was there present. Whether this was wisely done or no, I leave to my friends to determine." When he had signed the paper, he was told by Walpole, that the committee were not satisfied with his behaviour, nor could give such an account of it to the commons as might merit favour; and that they now thought a stricter confinement necessary than to his own house. "Here," says he, "Boscawen played the moralist, and Coningsby the Christian, but both very awkwardly." The messenger, in whose custody he was to be placed, was then called, and very decently asked by Coningsby, "if his house was secured by bars and bolts?" The messenger answered, "No," with astonishment. At which Coningsby very angrily said, "Sir, you must secure this prisoner; it is for the safety of the nation: if he escape, you shall answer for it." They had already printed their report; and in this examination were endeavouring to find proofs. He continued thus confined for some time; and Mr. Walpole, June 10, 1715, moved for an impeachment against him. What made him so acrimonious does not appear: he was by nature no thirster for blood. Prior was, a week after, committed to close custody, with orders that "no person should be admitted to see him without leave from the speaker." When, two years after, an act of grace was passed, he was excepted, and continued still in custody, which he had made less tedious by writing his Alma. He was, however, soon after discharged. He had now his liberty, but he had nothing else. Whatever the profit of his employments might have been, he had always spent it; and, at the age of fifty-three, was, with all his abilities, in danger of penury, having yet no solid revenue but from the fellowship of his college, which, when in his exaltation he was censured for retaining it, he said, he could live upon at last.
