What is it about the olfactory sense that seems to hint at absences as much as presences? Why does one recollect so many peripheral details about ‘that particular smell’ but not quite the odour itself? Perhaps smell forms the base, the foundation, for our sensory memories, sending out tentacles into visions, hearings, giving then nourishment, yet ultimately laying hidden, subterranean. It is only when, for some reason, one does not use a particular sense organ that one gains faculties related to the others. This seems especially true for the sense of smell.
