"The relationship between Wales and Ireland was an ambiguous one. There was much fruitful contact in the 'Age of Saints' but the Mabinogi does not offer a portrait of two countries in close Celtic embrace. In 1110, Madog ap Rhirid of Powys was glad to return to Wales because he 'could not bear the godless morals of the Irish'..."

Madog married.
