It seems you might be referring to the themes and motifs present in William Shakespeare's plays and their connection to Ovid's "Metamorphoses," which is a collection of mythological tales that often explore themes of transformation, love, and the complexities of human relationships.
Shakespeare's work frequently incorporates elements that resonate with Ovid's storytelling style. For instance, themes of love and transformation are central to plays like "A Midsummer Night's Dream," where characters undergo emotional and magical transformations in pursuit of love, a motif also prevalent in Ovid's narratives.
Similarly, "The Tempest" reflects themes of redemption and transformation akin to those found in Ovid's tales. The play explores not only physical transformation (as in the character of Caliban) but also personal and emotional growth, reminiscent of the changes faced by characters in Ovid's work.
