The thing about English ancient literature is that it wasn't written in Latin or greek and the saxon heritage is very much what the historians want you to read. Many of the personages that turn up in the Mabinogion, also turn up in the irish celtic cycle, such as the red branch and the stories of cuchulain and the fenians. But the welsh story cycles (or british really) have a much more lilting tone. Though the story of the Children of Llyr always brings tears to my eyes. It's about damn time British schools and universities reclaimed the celtic..gaelic..british part of their heritage.
