There have been exhibitions, indeed even a whole museum, dedicated to cleanliness: the Deutsches Hygiene Museum in Dresden, for instance (image 9), which was founded for the purpose of public education in hygiene and health, but which later embraced and diffused racist theories during the Nazi era. Yet there haven’t been many – or any, as far as I’m aware – devoted entirely to dirt. It’s all around us, yet historically we seem to have considered the subject unworthy of serious cultural examination. And the reasons for avoidance are just as interesting as the filthy matter currently under the microscope at the Wellcome Collection (see theartsdesk's review).
