William Wordsworth, Imaginative Regrets, l. 4
DEEP is the lamentation! Not alone
From Sages justly honoured by mankind;
But from the ghostly tenants of the wind,
Demons and Spirits, many a dolorous groan
Issues for that dominion overthrown:
Proud Tiber grieves, and far-off Ganges, blind
As his own worshippers: and Nile, reclined
Upon his monstrous urn, the farewell moan
Renews. Through every forest, cave, and den,
Where frauds were hatched of old, hath sorrow past--
Hangs o'er the Arabian Prophet's native Waste,
Where once his airy helpers schemed and planned
'Mid spectral lakes bemocking thirsty men,
And stalking pillars built of fiery sand.
