Welsh cleric and author Caradoc of Llancarfan, who wrote his "Life of Gildas" sometime between 1130 and 1150, recounts her being kidnapped and raped ("violatam et raptam") by Melwas, king of the "Summer Country" ("Aestiva Regio", perhaps meaning Somerset), and held prisoner at his stronghold at Glastonbury. The story states that Arthur spent a year searching for her and assembling an army to storm Melwas' fort when Gildas negotiates a peaceful resolution and reunites husband and wife. The episode seems to be related to an Old Irish abduction motif called the in which a mysterious stranger kidnaps a married woman and takes her to his home; the husband of the woman then rescues her against insurmountable odds. A seemingly related account was carved into the archivolt of Modena Cathedral in Italy, which most likely predates that telling. Here, Artus de Bretania and Isdernus approach a tower in which Mardoc is holding Winlogee, while on the other side Carrado (most likely Caradoc) fights Galvagin (Gawain) as the knights Galvariun and Che (Kay) approach. Isdernus is most certainly an incarnation of Yder (Edern ap Nudd), a Celtic hero whose name appears in "Culhwch and Olwen". Yeder is actually Guinevere's lover in a nearly-forgotten tradition mentioned in Béroul's 12th-century "Tristan". This is reflected in the later "Romanz du reis Yder", where his lover is Guinevere-like Queen Guenloie of Carvain (possibly Caerwent).
