The white and the red dragons respectively symbolised the Celtic and Saxon races, and Merlin's prophecy concerning the final overthrow of the Saxons by the Britons made a deep and lasting impression on the minds of the Welsh people for ages, and even nearly nine hundred years after Merlin's time. Owen Glyndwr found these prophecies highly instrumental in his favour when fighting against the English. According to a little book which I have in my possession entitled, "Prophwydoliaeth Myrddin Wyllt," (Merlin's prophecy), one Owen Lawgoch, who is tarrying in a foreign land, is to drive out the Saxons, and become King under the title of Henry the ninth. Welshmen of the present day, however, believe that Merlin's prophecy was fulfilled in the year 1485, when Henry VII., a Welshman leading a Welsh army to Bosworth Field, became King of England. There are also many prophecies here and there attributed to Merlin; some of which have been fulfilled, and others to be fulfilled in the future. He had foretold even of the railway train running along the Vale of Towy, which prediction has proved true: "Fe ddaw y gath a'r wenci ar hyd Glan Towi i lawr; Fe ddaw y milgi a'r llwynog i Aberhonddu fawr." "The cat and the weasel shall come down along the banks of Towy; The greyhound and the fox shall come into the town of Aber honddu," (Brecon). It is believed that the train has fulfilled these sayings. In the Vale of Towy, near Abergwili, there is a large stone in a field belonging to Tyllwyd farm. I went to see it myself, and several people in the neighbourhood informed me that a young man was killed when digging under this stone in search of hidden treasure, and that Merlin had prophesied about this. According to another prophecy of Merlin a fearful catastrophe awaits the town of Carmarthen:-- "Llanllwch a fu, Caerfyrddin a sudd, Abergwili a saif." (Llanllwch has been, Carmarthen shall sink, Abergwili shall stand). "Caerfyrddin, cei oer fore, Daear a'th lwnc, dwr i'th le." (Carmarthen, thou shalt have a cold morning, Earth shall swallow thee, water into thy place). The people of the neighbourhood even to this very day, more than half believe that Carmarthen is to sink. At the end of a long street in that town there is an old tree known as Merlin's Tree, in a very withered condition. Every care is taken to protect it from falling, as Merlin had prophesied that when this tree shall tumble down, the town of Carmarthen shall sink. "When Merlin's Tree shall tumble down. Then shall fall Carmarthen town!" (A Prophecy of Merlin). According to another prophecy attributed to the same ancient wizard, Carmarthen is to sink when Llyn Eiddwen, a lake in Cardiganshire, dries up.
