King Eochaid has horse's ears (Author: Unknown)

paragraph 8

Then the harper went to the house of the king, and was well received by him. He and his company were taken to the house where the king lay. ‘Strike up!’ said Eochaid. ‘Harp us something ingenious!’ ‘That is our intention,’ said they. They begin to play to him, and what they played was: ‘Eochaid, the man of the shield, has two horse's ears.’ ‘Let light and a candle be brought into the house!’ cried the king. When the light and the candles and shining lamps had come, he said: ‘Throw yourselves upon the chest of the harpers and bind them!’ And forthwith they were bound, and they continued in their fetters till the morning.
