XV.
Thus, counter to that ancient’s will malign,
Who them to the devouring river dooms,
Some names are rescued by the birds benign;
Wasteful Oblivion all the rest consumes.
Now swim about the stream those swans divine,
Now beat the buxom air with nimble plumes,
Till, near that impious river’s bank, they gain
A hill, and on that hill a hallowed fane.
XVI.
To Immortality ’tis sacred; there
A lovely nymph, that from the hill descends,
To the Lethean river makes repair;
Takes from those swans their burden, and suspends
The names about an image, raised in air
Upon a shaft, which in mid fane ascends;
There consecrates and fixes them so fast,
That all throughout eternity shall last.
XVII.
Of that old sire, and why he would dispense
Idly, all those fair names, as ’twould appear,
And of the birds and holy place, from whence
The nymph was to the river seen to steer,
The solemn mystery, and the secret sense,
Astolpho, marvelling, desired to hear;
And prayed the man of God would these unfold,
Who to the warrior thus their meaning told.
