Battle of the Pelennor Fields
"The Oxford Handbook of Music and Medievalism" treats the song as "fantasy medievalism", seeing allusions to multiple features of Tolkien's Middle-earth. It notes that the song "specifically alludes" to the Dark Lord and the Ringwraiths, while the "Queen of Light" mentioned is "possibly" the elf-queen Galadriel. It states that the battle in the song "has often been identified by fans" as the Battle of the Pelennor Fields. Describing the effect of the song, it writes that Plant makes use of the feeling of nostalgia with the "strain and desperation" in his "vocal cries" combined with the "haunting, pastoral soundscape" that together set up "the destructive world of war in opposition to an idealized and Arcadian peaceful home".
