No one in Annwn suspected Pwyll of being anyone else than their king. He spent the year in ruling the realm, in hunting, minstrelsy, and feasting. Both by day and night, he had the company of Arawn’s wife, the most beautiful woman he had ever yet seen, but he refrained from taking advantage of the trust placed in him. At last the day came when he was to meet Havgan in single combat. One blow settled it; for Pwyll, Havgan’s destined conqueror, thrust his antagonist an arm’s and a spear’s length over the crupper of his horse, breaking his shield and armour, and mortally wounding him. Havgan was carried away to die, and Pwyll, in the guise of Arawn, received the submission of the dead king’s subjects, and annexed his realm. Then he went back to Glyn Cûch, to keep his tryst with Arawn. They retook their own shapes, and each returned to his own kingdom. Pwyll learned that Dyfed had never been ruled so well, or been so prosperous, as during the year just passed. As for the King of Hades, he found his enemy gone, and his domains extended. And when he caressed his wife, she asked him why he did so now, after the lapse of a whole year. So he told her the truth, and they both agreed that they had indeed got a true friend in Pwyll. After this, the kings of Annwn and Dyfed made their friendship strong between them. From that time forward, says the story, Pwyll was no longer called Prince of Dyfed, but _Pen Annwn_, “the Head of Hades”. The second mythological incident in the Mabinogi of Pwyll, Prince of Dyfed, tells how the Head of Hades won his wife, Rhiannon, thought by Professor Rhys to have been a goddess either of the dawn or of the moon.[333] There was a mound outside Pwyll’s palace at Narberth which had a magical quality. To anyone who sat upon it there happened one of two things: either he received wounds and blows, or else he saw a wonder. One day, it occurred to Pwyll that he would like to try the experience of the mound. So he went and sat upon it. No unseen blows assailed Pwyll, but he had not been sitting long upon the mound before he saw, coming towards him, “a lady on a pure-white horse of large size, with a garment of shining gold around her”, riding very quietly. He sent a man on foot to ask her who she was, but, though she seemed to be moving so slowly, the man could not come up to her. He failed utterly to overtake her, and she passed on out of sight. The next day, Pwyll went again to the mound. The lady appeared, and, this time, Pwyll sent a horseman. At first, the horseman only ambled along at about the same pace at which the lady seemed to be going; then, failing to get near her, he urged his horse into a gallop. But, whether he rode slow or fast, he could come no closer to the lady than before, although she seemed to the eyes of those who watched to have been going only at a foot’s pace.
