One day he went forth to Caer Dathyl, to visit Math the son of Mathonwy. And on the day that he set out for Caer Dathyl, Blodeuwedd walked in the Court. And she heard the sound of a horn. And after the sound of the horn, behold a tired stag went by, with dogs and huntsmen following it. And after the dogs and the huntsmen there came a crowd of men on foot. “Send a youth,” said she, “to ask who yonder host may be.” So a youth went, and inquired who they were. “Gronw Pebyr is this, the lord of Penllyn,” said they. And thus the youth told her.
Gronw Pebyr pursued the stag, and by the river Cynvael he overtook the stag and killed it. And what with flaying the stag and baiting his dogs, he was there until the night began to close in upon him. And as the day departed and the night drew near, he came to the gate of the Court. “Verily,” said Blodeuwedd, “the Chieftain will speak ill of us if we let him at this hour depart to another land without inviting him in.” “Yes, truly, lady,” said they, “it will be most fitting to invite him.”
Then went messengers to meet him and bid him in. And he accepted her bidding gladly, and came to the Court, and Blodeuwedd went to meet him, and greeted him, and bade him welcome. “Lady,” said he, “Heaven repay thee thy kindness.”
When they had disaccoutred themselves, they went to sit down. And Blodeuwedd looked upon him, and from the moment that she looked on him she became filled with his love. And he gazed on her, and the same thought came unto him as unto her, so that he could not conceal from her that he loved her, but he declared unto her that he did so. Thereupon she was very joyful. And all their discourse that night was concerning the affection and love which they felt one for the other, and which in no longer space than one evening had arisen. And that evening passed they in each other’s company.
The next day he sought to depart. But she said, “I pray thee go not from me to-day.” And that night he tarried also. And that night they consulted by what means they might always be together. “There is none other counsel,” said he, “but that thou strive to learn from Llew Llaw Gyffes in what manner he will meet his death. And this must thou do under the semblance of solicitude concerning him.”
The next day Gronw sought to depart. “Verily,” said she, “I will counsel thee not to go from me to-day.” “At thy instance will I not go,” said he, “albeit, I must say, there is danger that the chief who owns the palace may return home.” “To-morrow,” answered she, “will I indeed permit thee to go forth.”
The next day he sought to go, and she hindered him not. “Be mindful,” said Gronw, “of what I have said unto thee, and converse with him fully, and that under the guise of the dalliance of love, and find out by what means he may come to his death.”
That night Llew Llaw Gyffes returned to his home. And the day they spent in discourse, and minstrelsy, and feasting. And at night they went to rest, and he spoke to Blodeuwedd once, and he spoke to her a second time. But, for all this, he could not get from her one word. “What aileth thee?” said he, “art thou well?” “I was thinking,” said she, “of that which thou didst never think of concerning me; for I was sorrowful as to thy death, lest thou shouldst go sooner than I.” “Heaven reward thy care for me,” said he, “but until Heaven take me I shall not easily be slain.” “For the sake of Heaven, and for mine, show me how thou mightest be slain. My memory in guarding is better than thine.” “I will tell thee gladly,” said he. “Not easily can I be slain, except by a wound. And the spear wherewith I am struck must be a year in the forming. And nothing must be done towards it except during the sacrifice on Sundays.” “Is this certain?” asked she. “It is in truth,” he answered. “And I cannot be slain within a house, nor without. I cannot be slain on horseback nor on foot.” “Verily,” said she, “in what manner then canst thou be slain?” “I will tell thee,” said he. “By making a bath for me by the side of a river, and by putting a roof over the cauldron, and thatching it well and tightly, and bringing a buck, and putting it beside the cauldron. Then if I place one foot on the buck’s back, and the other on the edge of the cauldron, whosoever strikes me thus will cause my death.” “Well,” said she, “I thank Heaven that it will be easy to avoid this.”
No sooner had she held this discourse than she sent to Gronw Pebyr. Gronw toiled at making the spear, and that day twelvemonth it was ready. And that very day he caused her to be informed thereof.
“Lord,” said Blodeuwedd unto Llew, “I have been thinking how it is possible that what thou didst tell me formerly can be true; wilt thou show me in what manner thou couldst stand at once upon the edge of a cauldron and upon a buck, if I prepare the bath for thee?” “I will show thee,” said he.
