He was by profession a man of letters of an uncommercial kind. He was a specialist in pessimism; had made a translation of Ecclesiastes of which eight copies a year were sold; and followed up the pessimism of Shakespear and Swift with keen interest. He delighted in a hideous conception which he called the theory of the cycles, according to which the history of mankind and the universe keeps eternally repeating itself without the slightest variation throughout all eternity; so that he had lived and died and had his goitre before and would live and die and have it again and again and again. He liked to believe that nothing that happened to him was completely novel: he was persuaded that he often had some recollection of its previous occurrence in the last cycle. He hunted out allusions to this favorite theory in his three favorite pessimists. He tried his hand occasionally at deciphering ancient inscriptions, reading them as people seem to read the stars, by discovering bears and bulls and swords and goats where, as it seems to me, no sane human being can see anything but stars higgledy-piggledy. Next to the translation of Ecclesiastes, his _magnum opus_ was his work on Shakespear's Sonnets, in which he accepted a previous identification of Mr W. H., the "onlie begetter" of the sonnets, with the Earl of Pembroke (William Herbert), and promulgated his own identification of Mistress Mary Fitton with the Dark Lady. Whether he was right or wrong about the Dark Lady did not matter urgently to me: she might have been Maria Tompkins for all I cared. But Tyler would have it that she was Mary Fitton; and he tracked Mary down from the first of her marriages in her teens to her tomb in Cheshire, whither he made a pilgrimage and whence returned in triumph with a picture of her statue, and the news that he was convinced she was a dark lady by traces of paint still discernible.
