"The Prologue" is a song by American electropop artist Halsey featured on her second studio album Hopeless Fountain Kingdom. The intro part of this song is the prologue of William Shakespeare's drama "Romeo and Juliet" which explains the title of the song.
"The Prologue" introduces listeners to the central concept of hopeless fountain kingdom. The album is loosely inspired by the play Romeo and Juliet by William Shakespeare. The introduction of the song is directly taken from the prologue of the play.
Halsey has rewritten it to be about the two houses Angelus and Aureum. The two famous star-crossed lovers are renamed Solis and Luna and are gender-swapped: Luna (Halsey) takes Romeo’s place, in the house of Aureum, and Solis (Halsey’s lover) takes Juliet’s place, in the good house of Angelus.
In ancient Roman religion and myth, Luna is the divine embodiment of the Moon and is often presented as the female complement of the Sun (Sol). The words together, ‘solis et Luna’ is a Latin phrase meaning ‘sunlight’.
