Step-by-step explanation:
The symbolization of Madeline's Vault can be interpreted in several ways depending on the context it is presented in. Within literary analysis, a vault might symbolize a final resting place that represents not only the end of life but also the sealing away of secrets or hidden maladies. It can be an allegory for the subconscious or a repository for suppressed emotions and memories. In a historical context, the preservation of Madeline's body could symbolize attempts to hold on to the past, to maintain lineage or traditions amidst societal change. From an art perspective, as seen in Gothic architecture, a vault may be a structural element unifying a space, which could symbolically unify or confine aspects of the character's lives who are associated with it. The allusion to mortuary art connects the vault to themes of mortality and the juxtaposition between death and beauty, suggesting a potentially deeper philosophical contemplation about human existence.
