Was it a person? And, if so, who?

That Memnon, it afterwards crossed my mind,

Was like the Old Man of the Dovrë, so called,

Just as he sat there, stiff and stark,

Planted on end on the stumps of pillars.—

But this most curious mongrel here,

This changeling, a lion and woman in one,—

Does he come to me, too, from a fairy-tale,

Or from a remembrance of something real?

From a fairy-tale? Ho, I remember the fellow!
