There used to be preserved at Llanddewi Church a remarkable fragment of a horn called "Madcorn yr Ych Bannog," that is, the core of the Bannog Ox's Morn, which, according to tradition, had been kept there as a valuable relic ever since the time of St. David. This horn is now at Llidiardau, Llanilar, kept privately. It has been pronounced by Professor Boyd Dawkins to have belonged to "the great urns (Bos Primigenius) that Charlemagne hunted in the forest of Aachen, and the Monks of St. Galle ate on their feast days." When St. David was preaching at Llanddewi at the great Synod, in the year 519, it is said that the ground on which he stood rose up and formed a hillock under his feet. Cressy recounts the miracle in the following words:--"When all the fathers assembled enjoined David to preach, he commanded a child which attended him, and had lately been restored to life by him, to spread a napkin under his feet; and, standing upon it, he began to expound the Gospel and the law to the auditory. All the while that this oration continued, a snow-white dove, descending from Heaven, sate upon his shoulders; and, moreover, the earth, on which he stood raised itself under him till it became a hill, from whence his voice, like a trumpet, was clearly heard and understood by all, both near and far off, on the top of which hill a church was afterwards built, and remains to this day." The people of Llanddewi Brefi told me that there is another tradition still extant in the neighbourhood, which says that as St. David was preaching on this great occasion, a nightingale appeared on the spot, and sang. The music of the bird was so sweet, that the people listened to the nightingale's song, instead of continuing to give their attention to the sermon. Seeing this, the Holy Saint David rebuked the congregation, and informed them that the nightingale should never again sing in the neighbourhood; and from that day till now the bird has never been heard there. According to the great historian George Owen, there is a different version of this story in Pembrokeshire. "St. David, being seriouse occupied in the night tyme in his divine orizons, was so troubled with the sweete tuninges of the nightingales, as that he could not fasten his minde upon heavenlie cogitacions, as at other tymes, being letted (hindered) by the melodie of the bird, praied unto the Almightie, that from that tyme forward there might never a nightingale sing within his Dioces, and this saieth our women (old wives' fables), was the cause of confininge of the bird out of this country."
