As translated by Lady Charlotte Guest, excerpted from Robert Graves's The White Goddess: A Historical Grammar of Poetic Myth:

Discover what it is:

The strong creature from before the Flood

Without flesh, without bone,

Without vein, without blood,

Without head, without feet ...

In field, in forest...

Without hand, without foot.

It is also as wide

As the surface of the earth,

And it was not born,

Nor was it seen ...
