A Pair of Blue Eyes carries more autobiographical associations than any other of Hardy's novels, having been written during his courtship of Emma Lavinia Gifford in North Cornwall. Miss Gifford is clearly paralleled in Elfride Swancourt, while Stephen Smith bears more than a passing resemblance to Hardy himself (much as he cared to deny it). The model for Henry Knight seems clearly to be Hardy's close friend and mentor, Horace Moule.
