In the manuscripts the Bull is referred to as "an Donn Cuailgne".  While
the word "Donn" means "brown" it is also the name of the ancient Irish God
of the Dead.  There is also a related story which tells how two malevolent
magicians take the shape of Bulls and resume a longstanding feud.

You can fool the woman
  - One of these days, you're gonna
     fool the man
Cos you've got the insight
  You can see a world of things
They can't understand.

You can say you're winning
  You can count the score
And say you know that they've lost.
  But you'll end up admitting that
The price is more than simply counting
  the cost.

Ah yes, they're blind already.
  They're blind to love, blind to pain,
Blind to hope, blind to gain.
  Ah you can fool them alright
But can you fool the beast?

You can fool the woman
  Anyone can see you're gonna
    fool the man.
Cos you've ways of knowing.
  You can tell their pride will
make them blind in the end.
  And leave them blindly gazing
