A heathen, cannibal king in Perlesvaus who possessed the sword that had beheaded St. John the Baptist.
His son was kidnapped by a giant, which made Gurguran forsake his pagan religion. Gawain came to Gurguranís kingdom in Scotland seeking the sword, and he accepted the challenge of rescuing Gurguranís son. Gawain killed the giant, but was unable to save the princeís life. Gurguran nevertheless gave Gawain the sword as a reward. Gurgurant cooked his sonís body and fed it to his followers. Gurguran then had himself baptized, taking the Christian name Archier.
