s you turn
Backward and forward to the echoes faint
Of your own footsteps--voices from the urn
Appear to wake, and shadows wild and quaint
Start from the frames which fence their aspects stern,
As if to ask how you can dare to keep
A vigil there, where all but death should sleep.

And the pale smile of beauties in the grave,
The charms of other days, in starlight gleams,
Glimmer on high; their buried locks still wave
Along the canvas; their eyes glance like dreams
On ours, or spars within some dusky cave,
But death is imaged in their shadowy beams.
A picture is the past; even ere its frame
Be gilt, who sate hath ceased to be the same.

As Juan mused on mutability,
Or on his mistress--terms synonymous--
No sound except the echo of his sigh
Or step ran sadly through that antique house;
When suddenly he heard, or thought so, nigh,
A supernatural agent--or a mouse,
Whose little nibbling rustle will embarrass
Most people as it plays along the arras.

It was no mouse, but lo! a monk, array'd
In cowl and beads and dusky garb, appear'd,
Now in the moonlight, and now lapsed in shade,
With steps that trod as heavy, yet unheard;
His garments only a slight murmur made;
He moved as shadowy as the sisters weird,
But slowly; and as he pass'd Juan by,
Glanced, without pausing, on him a bright eye.

Juan was petrified; he had heard a hint
Of such a spirit in these halls of old,
But thought, like most men, there was nothing in 't
Beyond the rumour which such spots unfold,
Coin'd from surviving superstition's mint,
Which passes ghosts in currency like gold,
But rarely seen, like gold compared with paper.
And did he see this? or was it a vapour?

Once, twice, thrice pass'd, repass'd--the thing of air,
Or earth beneath, or heaven, or t' other place;
And Juan gazed upon it with a stare,
Yet could not speak or move; but, on its base
As stands a statue, stood: he felt his hair
Twine like a knot of snakes around his face;
He tax'd his tongue for words, which were not granted,
To ask the reverend person what he wanted.

The third time, after a still longer pause,
The shadow pass'd away--but where? the hall
Was long, and thus far there was no great caus
