The Four Branches of the Mabinogi are the oldest and most famous legends in Wales. First written down around 800 years ago, they were being told for many years before that, captivating audiences with their unique mix of magic, romance and adventure. They conjure a world of giants, wizards, enchantments where families wage war and even some people who can transform into animals! Y Mabinogi yw chwedlau hynaf ac enwocaf Cymru, a'r Pedair Cainc yw straeon craidd y chwedlau hyn. Er iddyn nhw gael eu hysgrifennu ar femrwn tua wyth canrif yn ol, bu storiwyr yn eu hadrodd ar lafar sawl canrif cyn hynny. Mae'r chwedlau hyn wedi para cyhyd am eu bod yn dal i allu cydio yn y dychymyg a'u hud a lledrith, eu hantur, eu rhamant a'u rhyfeddodau unigryw.
