Soon afterwards Elphin, with his usual ill luck, managed to offend the powerful King Maelgwn, who cast him into a dungeon barred by thirteen locked doors. But when father Gwyddno was lamenting his son's ill fate, the child Taliesin bade him be of good cheer, since he was going to rescue him. Setting off at daybreak he reached the King's palace at the time of the evening meal, and entered the hall just as the bards were beginning to sing the praises of the King, as was their custom every evening. Then Taliesin cast a spell upon these bards, so that instead of singing they could only pout out their lips and make mouths at the King. He forced them also, by his magic power, to tap their fingers on their mouths, as they tried in vain to sing, making a curious sound like "Bler-m! Bler-m!" The King, naturally, thought they were treating him with great disrespect, and ordered one of his squires to give a blow to the chief bard; and the squire took a broom, and struck him on the head, so that he fell back on his seat. This rough treatment seemed to bring him to his senses, and he then explained that they could not help themselves, but had been put under a spell by a spirit, who was sitting in a corner of the hall under the form of a child. So the King ordered the squire to fetch the child; and Taliesin, nothing loth, was brought up to the head of the table. Being asked who he was and whence he came, he at once proceeded to sing another wonderful song, in which he informed them that he was the chief bard of Elphin, that his native country was the land of Cherubim, but that at present he was dwelling upon this earth, and might even stay here until the Judgment Day. The King and his nobles marvelled greatly, for they had never heard the like from a boy so young as he. But as he was the bard of Elphin, who had offended His Majesty, the King determined that his own bards should get the better of him in song. So he ordered the chief bard to stand forth, and then all the four and twenty of them, to strive with Taliesin. But when they came forward to do his bidding they could do no other than play "Bler-m! Bler-m!" on their lips. Then the King, angry and disappointed, asked the boy Taliesin his errand. And the child replied in song: "I am come to deliver Elphin, who is imprisoned in this castle, behind thirteen locks." "I will never let him go," said the King.
