The last volume of the 'Iliad' appeared in the spring of 1720, and in it Pope gave a renewed proof of his independence by dedicating the whole work, not to some lord who would have rewarded him with a handsome present, but to his old acquaintance, Congreve, the last survivor of the brilliant comic dramatists of Dryden's day. And now resting for a time from his long labors, Pope turned to the adornment and cultivation of the little house and garden that he had leased at Twickenham. Pope's father had died in 1717, and the poet, rejecting politely but firmly the suggestion of his friend, Atterbury, that he might now turn Protestant, devoted himself with double tenderness to the care of his aged and infirm mother. He brought her with him to Twickenham, where she lived till 1733, dying in that year at the great age of ninety-one. It may have been partly on her account that Pope pitched upon Twickenham as his abiding place. Beautifully situated on the banks of the Thames, it was at once a quiet country place and yet of easy access to London, to Hampton Court, or to Kew. The five acres of land that lay about the house furnished Pope with inexhaustible entertainment for the rest of his life. He "twisted and twirled and harmonized" his bit of ground "till it appeared two or three sweet little lawns opening and opening beyond one another, the whole surrounded by impenetrable woods." Following the taste of his times in landscape gardening, he adorned his lawns with artificial mounds, a shell temple, an obelisk, and a colonnade. But the crowning glory was the grotto, a tunnel decorated fantastically with shells and bits of looking-glass, which Pope dug under a road that ran through his grounds. Here Pope received in state, and his house and garden was for years the center of the most brilliant society in England. Here Swift came on his rare visits from Ireland, and Bolingbroke on his return from exile. Arbuthnot, Pope's beloved physician, was a frequent visitor, and Peterborough, one of the most distinguished of English soldiers, condescended to help lay out the garden. Congreve came too, at times, and Gay, the laziest and most good-natured of poets. Nor was the society of women lacking at these gatherings. Lady Mary Wortley Montague, the wittiest woman in England, was often there, until her bitter quarrel with the poet; the grim old Duchess of Marlborough appeared once or twice in Pope's last years; and the Princess of Wales came with her husband to inspire the leaders of the opposition to the hated Walpole and the miserly king. And from first to last, the good angel of the place was the blue-eyed, sweet-tempered Patty Blount, Pope's best and dearest friend.
