However, aware that he had encountered in these men powers beyond his understanding, and in a little awe and fear, Boia granted Dewi the land at Glyn Rhosyn for his community. Sure enough, as soon as he did so, the warriors were cured of their affliction and the livestock restored to life.
Boia’s wife however, was not so easily won over. She sent her maidens to bathe naked in the River Alun, to tempt Dewi’s followers away from their vows, but they held fast, and through fasting and prayer Dewi helped his companions withstand these great temptations. Finally, Boia’s wife led her step-daughter Dunawd down to the river Alun and sacrificed her to the old gods in an attempt to drive the Christian men away. Her failure drove her to utter madness and she fled, never to be seen again.
Boia was devastated by his loss and again tried to attack David, but an Irish chieftain by the name of Lisci had just landed nearby, and attacked Boia’s poorly defended camp and killed him. Lisci’s name remains in the landscape to this day in the name Porthlysgi.
To complete the tale with one final miracle, fire poured down from heaven during a great thunderstorm and the whole of Boia’s hill fort settlement was destroyed by the inferno. And all this must be utterly true because over 1400 years later, when archaeologists excavated Clegyr Boia, what you think they discovered? Beneath the turf lay the charred remains of huts and storehouses.
