In the year 1170 AD "Mad-Dog" Madog Ap Owain, Prince of Gwynedd, disappears from the historical records. For centuries there has been speculation across Wales and the wider, non-Welsh-speaking world as to what could have become of this handsome, popular prince who had been surely destined for greatness. The last written record of Prince Madog is contained in "Hanes y Brenin", (History of the King) a four volume history of the kings of Gwynedd written by the monks of Caldey Abbey at the express command of King Dafydd, successor to Madog's father, King Owain.
