Hysterica passio of its own emptiness?

Here at right of the entrance this bronze head,
Human, superhuman, a bird's round eye,
Everything else withered and mummy-dead.
What great tomb-haunter sweeps the distant sky
(Something may linger there though all else die
And finds there nothing to make its tetror less
Hysterica passio of its own emptiness?


William Butler Yeats
