Thanks to Ellen Fox for tweeting about this.
I know there are subtitles, but for convenience. below there is a translation into English:
I am Taliesin. I sing perfect metre,
Which will last to the end of the world.
My patron is Elphin…
I know why there is an echo in a hollow;
Why silver gleams; why breath is black; why liver is bloody;
Why a cow has horns; why a woman is affectionate;
Why milk is white; why holly is green;
Why a kid is bearded; why the cow-parsnip is hollow;
Why brine is salt; why ale is bitter;
Why the linnet is green and berries red;
Why a cuckoo complains; why it sings;
I know where the cuckoos of summer are in winter.
I know what beasts there are at the bottom of the sea;
How many spears in battle; how may drops in a shower;
Why a river drowned Pharaoh’s people;
Why fishes have scales.
Why a white swan has black feet…
I have been a blue salmon,
I have been a dog, a stag, a roebuck on the mountain,
A stock, a spade, an axe in the hand,
A stallion, a bull, a buck,
I was reaped and placed in an oven;
I fell to the ground when I was being roasted
And a hen swallowed me.
For nine nights was I in her crop.
I have been dead, I have been alive.
I am Taliesin.
