The answer is The Roman goddess of the dawn.
Aurora is the Roman goddess of the dawn, which aligns with the title "Aurora Awakes" as it suggests the beginning of a new day or a new era. This is a common interpretation in literature and music, where dawn symbolizes awakening or renewal.
While "Aurora" is the name of the princess in Disney's Sleeping Beauty, this is less likely to be the reference in John Mackey's work, which often draws on broader cultural or mythological themes.
The northern lights, or aurora borealis, are a natural light display in the Earth's sky. Although they share the name "Aurora," they are not typically personified or used in the context of awakening, making this option less likely.
There is no widely known information suggesting that John Mackey named the piece after his eldest child, making this option unlikely.
Aurora is not known as a daughter of Poseidon in mythology. This option does not align with established mythological references.
