"When Shelley's corpse washed ashore, a friend identified it by a copy of Keats's 1820 volume in the coat pocket, which he knew Shelley had taken with him. Then, after cremation in which Shelley's heart, hardened by calcium, did not burn, this same friend snatched it from the embers and presented it to Mary Shelley, who kept it thereafter in her desk, wrapped in a copy of 'Adonais."
