It was a Temple, such as mortal hand
Has never built, nor ecstasy, nor dream _560
Reared in the cities of enchanted land:
'Twas likest Heaven, ere yet day's purple stream
Ebbs o'er the western forest, while the gleam
Of the unrisen moon among the clouds
Is gathering--when with many a golden beam _565
The thronging constellations rush in crowds,
Paving with fire the sky and the marmoreal floods.

Like what may be conceived of this vast dome,
When from the depths which thought can seldom pierce
Genius beholds it rise, his native home, _570
Girt by the deserts of the Universe;
Yet, nor in painting's light, or mightier verse,
Or sculpture's marble language, can invest
That shape to mortal sense--such glooms immerse
That incommunicable sight, and rest _575
Upon the labouring brain and overburdened breast.

Winding among the lawny islands fair,
Whose blosmy forests starred the shadowy deep,
The wingless boat paused where an ivory stair
Its fretwork in the crystal sea did steep, _580
Encircling that vast Fane's aerial heap:
We disembarked, and through a portal wide
We passed--whose roof of moonstone carved, did keep
A glimmering o'er the forms on every side,
