local sea-god, and like Manannan identified with the waves, and yet separate from them, since they mourn his death. The _Mabinogi_ gives us the _débris_ of myths explaining how an anthropomorphic sea-god was connected with the goddess Arianrhod and slain by a god Govannon. Another _Mabinogion_ group is that of Pwyll, prince of Dyved, his wife Rhiannon, and their son Pryderi.[395] Pwyll agrees with Arawn, king of Annwfn (Elysium), to reign over his kingdom for a year. At the end of that time he slays Arawn's rival Havgan. Arawn sends him gifts, and Pwyll is now known as Pen or Head of Annwfn, a title showing that he was once a god, belonging to the gods' land, later identified with the Christian Hades. Pwyll now agrees with Rhiannon,[396] who appears mysteriously on a magic hillock, and whom he captures, to rid her of an unwelcome suitor Gwawl. He imprisons him in a magical bag, and Rhiannon weds Pwyll. The story thus resolves itself into the formula of the Fairy Bride, but it paves the way for the vengeance taken on Pryderi and Rhiannon by Gwawl's friend Llwyt. Rhiannon has a son who is stolen as soon as born. She is accused of slaying him and is degraded, but Teyrnon recovers the child from its super-human robber and calls him Gwri. As he grows up, Teyrnon notices his resemblance to Pwyll, and takes him to his court. Rhiannon is reinstated, and because she cries that her anguish (_pryderi_) is gone, the boy is now called Pryderi. Here, again, we have _Märchen_ incidents, which also appear in the Fionn saga.[397] Though there is little that is mythological here, it is evident that Pwyll is a god and Rhiannon a goddess, whose early importance, like that of other Celtic goddesses, appears from her name, a corruption of Rigantona, "great queen." Elsewhere we hear of her magic birds whose song charmed Bran's companions for seven years, and of her marriage to Manawyddan--an old myth in which Manawyddan may have been Pryderi's father, while possibly in some other myth Pryderi may have been child of Rigantona and Teyrnon (=Tigernonos, "king").[398] We may postulate an old Rhiannon saga, fragments of which are to be found in the _Mabinogi_, and there may have been more than one goddess called Rigantona, later fused into one. But in the tales she is merely a queen of old romance.
