Looking into the idea of 'hole' in general, I remembered I've visited this work by Doris Salcedo two years ago in Tate Modern. Here is a short description of the work:
Shibboleth asks questions about the interaction of sculpture and space, about architecture and the values it enshrines, and about the shaky ideological foundations on which Western notions of modernity are built.
In particular, Salcedo is addressing a long legacy of racism and colonialism that underlies the modern world. A ‘shibboleth’ is a custom, phrase or use of language that acts as a test of belonging to a particular social group or class. By definition, it is used to exclude those deemed unsuitable to join this group.
Thoughts: Although this work doesn't relate much to the Victorian world or the underworld I've been investigating it. But, interestingly it questions the foundation of the modernity of the Western world. This relates to the idea of a class system and how we are divided. Therefore, it might not seem relevant from the start, but the meaning of the piece bears strong similarities to the establishments of the modern world and if we are accepted or not. Referring back to an Underworld society.
