the Birdless spots and Birdless tarns,
What sort of nature they are furnished with.
First, as to name of "birdless,"- that derives
From very fact, because they noxious be
Unto all birds. For when above those spots
In horizontal flight the birds have come,
Forgetting to oar with wings, they furl their sails,
And, with down-drooping of their delicate necks,
Fall headlong into earth, if haply such
The nature of the spots, or into water,
If haply spreads thereunder Birdless tarn.
Such spot's at Cumae, where the mountains smoke,
Charged with the pungent sulphur, and increased
With steaming springs. And such a spot there is
Within the walls of Athens, even there
On summit of Acropolis, beside
Fane of Tritonian Pallas bountiful,
Where never cawing crows can wing their course,
Not even when smoke the altars with good gifts,-
But evermore they flee- yet not from wrath
Of Pallas, grieved at that espial old,
As poets of the Greeks have sung the tale;
But very nature of the place compels.
