So peered with airy head, below, above,
The castle at its toils, the lapwings love
To glean among at grape-time. Pass within.
A maze of corridors contrived for sin,
Dusk winding-stairs, dim galleries got past,
You gain the inmost chambers, gain at last
A maple-panelled room: that haze which seems
Floating about the panel, if there gleams
A sunbeam over it, will turn to gold
And in light-graven characters unfold
