In Katabasis there is a recurring highly symbolic fruit, the pomegranate, which embodies both sweetness and bitterness and has a symbolic history of fertility and death across many different cultures. In this work, Marshall explores these themes, drawing from the Greek myth of Persephone, who is bound to Hades by consuming pomegranate seeds, resulting in her cyclical journey between the underworld and the earth. Marshall's lino paintings blend personal experience with mythology, portraying the pomegranate as an emblem of the cyclical nature of life and the interplay of pleasure and pain. In her works she juxtaposes ancient symbols and contemporary elements, creating an exploration of memory, mythology, and rebirth.
