"Odysseus" Cronus.(When he refused to die)( the Sirens are the birds of Rhiannon,who sang at Harlech and of Bran)The Sirens Welcome to Odysseus.[Cronus Odyyseus steer your boat Towards silver island whence we sing.Here you shall pass your days through a thick growing Alder wood.We clearly see, but are not seen hidden in a golden haze.Our hair the hue of Barley sheaf,our eyes the hue of Blackbirds eggs,our cheeks like asphodel.Here the wld apple blossoms yet.Wrens nest in the silver branches play and prohesy you well.Here nothing ill or harsh is found. Cronus Odysseus,steer your boat across these placid straits,with each of us in turn to lay.Taking your plesures on young grass,that for your coming waits.No grief nor gloom,sickness nor death disturb our long tranquility,No treachary,no greed.Compared with this,what are the plains of Elis,where you eylad as king.a wilderness indeed.A starry crown awaits your head,here a feast is spread for you of swineflesh,milk and mead.]
