Thus, Centaurs and the limbs of Scyllas, thus
The Cerberus-visages of dogs we see,
And images of people gone before--
Dead men whose bones earth bosomed long ago;
Because the images of every kind
Are everywhere about us borne--in part
Those which are           in the very air
Of own accord, in part those others which
From divers things do part away, and those
Which are compounded, made from out their shapes.
