The Formulation of A Quartet: Understanding The Raven Cycle in Conjunction with the Myth.
One of the key things in Maggie Stiefvater’s The Raven Cycle is the establishment of a series of parallels between our main quartet - Gansey, Blue, Ronan and Adam - and the medieval quartet - Glendower, Gwenllian, Artemus & The Third Sleeper. It’s become especially pertinent as of Blue Lily Lily Blue and will, I imagine, continue to be so in The Raven King.
However, the parallels aren’t only between the main quartet and the medieval quartet. There’s a background parallel likely familiar to anyone familiar with the Arthurian Legend, that of the Arthurian quartet - Arthur, Merlin, Gwen & Morgana - and also influences that are being taken, by Stiefvater’s own admission, of Susan Cooper’s The Dark is Rising Sequence and the trio formed of Bran, Will and Jane.
Each of these groups is different, with their own relationship amongst the members and their own outcome of the story. But there are striking commonalities between the quartets and the individual roles played by each of the members, and in analysing these it becomes possible to start extrapolating possible endings and events of The Raven King, and what it will mean for each of The Raven Cycle trio.
