 For example, Carl Grey Martin notes that both parts include graphic depictions of nobles in states of physical distress, offering the possibility of reading Gawain's fight with Galeron as a kind of chivalric equivalent to the ghost's spiritual purgation.The first episode, featuring characters who, while on a hunt, are plunged into darkness before meeting a ghost, has strong thematic similarities to another stanzaic alliterative poem, "The Three Dead Kings", and seems to be derived from a popular legend of Saint Gregory.The "Awntyrs off Arthure" is written in a form of alliterative verse combining the usual four-stress alliterative line with a rhyme "ABABABABCDDDC" in a thirteen-line stanza; the density of alliteration is higher than in any other Middle English poem, with over half of its lines containing four alliterating stresses rather than the customary three.
