the rear diminishing away,--
Till a faint dawn surpris'd them. Glaucus cried,
"Behold! behold, the palace of his pride!
God Neptune's palaces!" With noise increas'd, 840
They shoulder'd on towards that brightening cast.
At every onward step proud domes arose
In prospect,--diamond gleams, and golden glows
Of amber 'gainst their faces levelling.
Joyous, and many as the leaves in spring,
Still onward; still the splendour gradual swell'd.
Rich opal domes were seen, on high upheld
By jasper pillars, letting through their shafts
A blush of coral. Copious wonder-draughts
Each gazer drank; and deeper drank more near: 850
For what poor mortals fragment up, as mere
As marble was there lavish, to the vast
Of one fair palace, that far far surpass'd,
Even for common bulk, those olden three,
Memphis, and Babylon, and Nineveh.

As large, as bright, as colour'd as the bow
Of Iris, when unfading it doth shew
Beyond a silvery shower, was the arch
Through which this Paphian army took its march,
Into the outer courts of Neptune's state: 860
Whence could be seen, direct, a golden gate,
To which the leaders sped; but not half raught
Ere it burst open swift as fairy thought,
And made those dazzled thousands veil their eyes
Like callow eagles at the first sunrise.
Soon with an eagle nativeness their gaze
Ripe from hue-golden swoons took all the blaze,
And then, behold! large Neptune on his throne
Of emerald deep: yet not exalt alone;
At his right hand stood winged Love, and on 870
His left sat smiling Beauty's paragon.

Far as the mariner on highest mast
Can see all round upon the calmed vast,
So wide was Neptune's hall: and as the blue
Doth vault the waters, so the waters drew
Their doming curtains, high, magnificent,
Aw'd from the throne aloof;--and when storm-rent
Disclos'd the thunder-gloomings in Jove's air;
But sooth'd as now, flash'd sudden everywhere,
Noiseless, sub-marine cloudlets, glittering 880
Death to a human eye: for there did spring
From natural west, and east, and south, and north,
A light as of four sunsets, blazing forth
A gold-green zenith 'bove the Sea-God's head.
Of lucid depth the floor, and far outspread
As breezeless lake, on which the slim canoe
Of feather'd Indian darts about, as through
The delicatest air: air
