Ceridwen and Taliesin

Silver moonlight dances from the mists of Tegid's shore
 A lady looks upon her son like many times before
 And she touches his face, fingers wet with the tears falling
 Her daughter stands beside her, the fairest in the land
 How her son became so cursed she cannot understand
 But this mother's love is as strong as her heart is beating
 And she calls to the earth, and the earth hears her calling
 High up in the mountains Dinas Affaraon stands tall
 All magic and all mysteries are held within these walls
 So she walks to the door; as she does, the door it opens
 Teach to me the mystery of the cauldron's brew
 Let utter darkness give way to light and be reborn anew
 Then the Awen will shine from the brow of the eagle of the sea
 And all will know his name, from this land to the people of the sídhe
 The lady set the cauldron's fire, tended by the hand
 Of Gwion Bach the innocent and Morda the blind man
 Who reached out his hand; place more wood, keep the cauldron boiling
 Then Morda he fell asleep, alas he didn't see
 Wood upon wood was added, the inferno was the key
 To unlock the door of the Awen's greatest mystery
 Three drops, burning skin, and it's Gwion who gained the power to see
 The cauldron cracks, the poison creeps slowly across the land
 To kill the horses of Garanhir at the lakeshore where they stand
 Drinking and not knowing their fate
 As a hare runs fast across the land
 Ceridwen, Ceridwen, lady of the cauldron, come see what they have done
 Stolen your cauldron's power and betrayed your only son
 Your eyes wide, lips curl, anger on your face
 Change your shape now, lady; be the hound, begin the chase
 I shall be a running hare, with sorrow and with mickle care
 (Then I shall be a greyhound bitch and tear you from your skin)
 Then I shall be a flying wren: the king of birds, the king of men
 (So I shall be a falcon grey and tear you from your skin)
 Then I shall be a salmon sleek, darting through a shallow creek
 (So I shall be an otter bitch and wrest you from your skin)
 I shall be a grain beneath the sun and you will never know which one
 (Then I shall be a great black hen and take you deep within)
 Now you may be forgiven to think my tale is over and done
 But nine moons later she gave birth to a son
 That she wanted to kill, but she placed in a coracle on the sea
 Garanhir's salmon weir; a catch was guaranteed
 But on this day a baby boy cried out to be freed
 A radiant brow shining bright for all to plainly see
 Taliesin is your name, the greatest bard that this land will ever see
