In one corner of a wall there are a number of framed photographs, all hung close together. Photographs of whom? Of you at various ages, and of many other people, men and women, and also very old photographs as if taken from a family album; but together they seem to have a function, not so much of recalling specific people, as of forming a montage of the stratifications of existence. The frames are all different, nineteenth-century Art Nouveau floral forms, frames in silver, copper, enamel, tortoiseshell, leather, carved wood; they may reflect the notion of enhancing those fragments of real life, but they may also be a collection of frames, and the photographs may be there only to occupy them; in fact some frames are occupied by pictures clipped from newspapers, one encloses an illegible page of an old letter, another is empty.
