After having been long in indirect communication with the exiled family, he, in 1717, began to correspond directly with the Pretender. The first letter of the correspondence is extant. In that letter Atterbury boasts of having, during many years past, neglected no opportunity of serving the Jacobite cause. "My daily prayer," he says, "is that you may have success. May I live to see that day, and live no longer than I do what is in my power to forward it." It is to be remembered that he who wrote thus was a man bound to set to the church of which he was overseer an example of strict probity; that he had repeatedly sworn allegiance to the House of Brunswick; that he had assisted in placing the crown on the head of George I., and that he had abjured James III., "without equivocation or mental reservation, on the true faith of a Christian."
It is agreeable to turn from his public to his private life. His turbulent spirit, wearied with faction and treason, now and then required repose, and found it in domestic endearments, and in the society of the most illustrious of the living and of the dead. Of his wife little is known: but between him and his daughter there was an affection singularly close and tender. The gentleness of his manners when he was in the company of a few friends was such as seemed hardly credible to those who knew him only by his writings and speeches. The charm of his "softer hour" has been commemorated by one of those friends in imperishable verse. Though Atterbury's classical attainments were not great, his taste in English literature was excellent; and his admiration of genius was so strong that it overpowered even his political and religious antipathies. His fondness for Milton, the mortal enemy of the Stuarts and of the church, was such as to many Tories seemed a crime. On the sad night on which Addison was laid in the chapel of Henry VII., the Westminster boys remarked that Atterbury read the funeral service with a peculiar tenderness and solemnity. The favourite companions, however, of the great Tory prelate were, as might have been expected, men whose politics had at least a tinge of Toryism. He lived on friendly terms with Swift, Arbuthnot, and Gay. With Prior he had a close intimacy, which some misunderstanding about public affairs at last dissolved. Pope found in Atterbury, not only a warm admirer, but a most faithful, fearless, and judicious adviser. The poet was a frequent guest at the episcopal palace among the elms of Bromley, and entertained not the slightest suspicion that his host, now declining in years, confined to an easy chair by gout, and apparently devoted to literature, was deeply concerned in criminal and perilous designs against the government.
The spirit of the Jacobites had been cowed by the events of 1715. It revived in 1721. The failure of the South Sea project, the panic in the money market, the downfall of great commercial houses, the distress from which no part of the kingdom was exempt, had produced general discontent. It seemed not improbable that at such a moment an insurrection might be successful. An insurrection was planned. The streets of London were to be barricaded; the Tower and the Bank were to be surprised; King George, his family, and his chief captains and councillors, were to be arrested; and King James was to be proclaimed. The design became known to the Duke of Orleans, regent of France, who was on terms of friendship with the House of Hanover. He put the English government on its guard. Some of the chief malecontents were committed to prison; and among them was Atterbury. No bishop of the Church of England had been taken into custody since that memorable day when the applauses and prayers of all London had followed the seven bishops to the gate of the Tower. The Opposition entertained some hope that it might be possible to excite among the people an enthusiasm resembling that of their fathers, who rushed into the waters of the Thames to implore the blessing of Sancroft. Pictures of the heroic confessor in his cell were exhibited at the shop windows. Verses in his praise were sung about the streets. The restraints by which he was prevented from communicating with his accomplices were represented as cruelties worthy of the dungeons of the Inquisition. Strong appeals were made to the priesthood. Would they tamely permit so gross an insult to be offered to their cloth? Would they suffer the ablest, the most eloquent member of their profession, the man who had so often stood up for their rights against the civil power, to be treated like the vilest of mankind? There was considerable excitement; but it was allayed by a temperate and artful letter to the clergy, the work, in all probability, of Bishop Gibson, who stood high in the favour of Walpole, and shortly after became minister for ecclesiastical affairs.
Atterbury remained in close confinement during some months. He had carried on his correspondence with the exiled family so cautiously that the circumstantial proofs of his guilt, though sufficient to produce entire moral conviction, were not sufficient to justify legal conviction. He could be reached only by a bill of pains and penalties. Such a bill the Whig party, then decidedly predominant in both houses, was quite prepared to support. Many hot-headed members of that party were eager to follow the precedent which had been set in the case of Sir John Fenwick, and to pass an act for cutting off the bishop's head. Cadogan, who commanded the army, a brave soldier, but a headstrong politician, is said to have exclaimed with great vehemence: "Fling him to the lions in the Tower." But the wiser and more humane Walpole was always unwilling to shed blood; and his influence prevailed. When Parliament met, the evidence against the bishop was laid before committees of both houses. Those committees reported that his guilt was proved. In the Commons a resolution, pronouncing him a traitor, was carried by nearly two to one. A bill was then introduced which provided that he should be deprived of his spiritual dignities, that he should be banished for life, and that no British subject should hold any intercourse with him except by the royal permission.
This bill passed the Commons with little difficulty. For the bishop, though invited to defend himself, chose to reserve his defence for the assembly of which he was a member. In the Lords the contest was sharp. The young Duke of Wharton, distinguished by his parts, his dissoluteness, and his versatility, spoke for Atterbury with great effect; and Atterbury's own voice was heard for the last time by that unfriendly audience which had so often listened to him with mingled aversion and delight. He produced few witnesses; nor did those witnesses say much that could be of service to him. Among them was Pope. He was called to prove that, while he was an inmate of the palace at Bromley, the bishop's time was completely occupied by literary and domestic matters, and that no leisure was left for plotting. But Pope, who was quite unaccustomed to speak in public, lost his head, and, as he afterwards owned, though he had only ten words to say, made two or three blunders.
The bill finally passed the Lords by eighty-three votes to forty-three. The bishops, with a single exception, were in the majority. Their conduct drew on them a sharp taunt from Lord Bathurst, a warm friend of Atterbury and a zealous Tory. "The wild Indians," he said, "give no quarter, because they believe that they shall inherit the skill and prowess of every adversary whom they destroy. Perhaps the animosity of the right reverend prelates to their brother may be explained in the same way."
Atterbury took leave of those whom he loved with a dignity and tenderness worthy of a better man. Three fine lines of his favourite poet were often in his mouth:—
"Some natural tears he dropped, but wiped them soon:
The world was all before him, where to chuse
His place of rest, and Providence his guide."
At parting he presented Pope with a Bible, and said, with a disingenuousness of which no man who had studied the Bible to much purpose would have been guilty: "If ever you learn that I have any dealings with the Pretender, I give you leave to say that my punishment is just." Pope at this time really believed the bishop to be an injured man. Arbuthnot seems to have been of the same opinion. Swift, a few months later,
