" In Poe’s story the keeper had no name but the dog did, Neptune. ‘Large as he is,’ says the lighthouse keeper, Neptune ‘is not to be taken into consideration as ‘society’. Would to Heaven I had ever found in ‘society’ one half so much faith as in this poor dog:- in such case i and ‘society’ might never have parted’. Neptune is the name of the Roman god or the seas, me the dog in Pope’s story is a water dog, the keeper’s only companion. He doesn’t take the place of society, he exceeds it. He is unadulterated company. Pure company. "
