Henry James: Autobiography

What a composition, for instance again I am capable at this hour of explaining, the conditions of felicity in which I became aware, one afternoon during a renewed gape before the Bacchus and Ariadne, first that a little gentleman beside me and talking with the greatest vivacity to another gentleman was extremely remarkable, second that he had the largest and most chevelu auburn head I had ever seen perched on a scarce perceptible body, third that I held some scrap of a clue to his identity, which couldn't fail to be eminent, fourth that this tag of association was with nothing less than a small photograph sent me westward across the sea a few months before, and fifth that the sitter for the photograph had been the author of Atalanta in Calydon and Poems and Ballads!
