It is probable that the Pope himself was among those who read this celebrated letter with pleasure. He had some months before dismissed Castelmaine in a manner which showed little regard for the feelings of Castelmaine's master. Innocent thoroughly disliked the whole domestic and foreign policy of the English government. He saw that the unjust and impolitic measures of the Jesuitical cabal were far more likely to make the penal laws perpetual than to bring about an abolition of the test. His quarrel with the court of Versailles was every day becoming more and more serious; nor could he, either in his character of temporal prince or in his character of Sovereign Pontiff, feel cordial friendship for a vassal of that court. Castelmaine was ill qualified to remove these disgusts. He was indeed well acquainted with Rome, and was, for a layman, deeply read in theological controversy.275 But he had none of the address which his post required; and, even had he been a diplomatist of the greatest ability, there was a circumstance which would have disqualified him for the particular mission on which he had been sent. He was known all over Europe as the husband of the most shameless of women; and he was known in no other way. It was impossible to speak to him or of him without remembering in what manner the very title by which he was called had been acquired.
This circumstance would have mattered little if he had been accredited to some dissolute court, such as that in which the Marchioness of Montespan had lately been dominant. But there was an obvious impropriety in sending him on an embassy rather of a spiritual than of a secular nature to a pontiff of primitive austerity. The Protestants all over Europe sneered; and Innocent, already unfavourably disposed to the English government, considered the compliment which had been paid him, at so much risk and at so heavy a cost, as little better than an affront.
