Often and oft he waters Aegypt o'er,
Either because in summer against his mouths
Come those northwinds which at that time of year
Men name the Etesian blasts, and, blowing thus
Upstream, retard, and, forcing back his waves,
Fill him o'erfull and force his flow to stop.
For out of doubt these blasts which driven be
From icy constellations of the pole
Are borne straight up the river. Comes that river
From forth the sultry places down the south,
Rising far up in midmost realm of day,
Among black generations of strong men
With sun-baked skins. 'Tis possible, besides,
That a big bulk of piled sand may bar
His mouths against his onward waves, when sea,
Wild in the winds, tumbles the sand to inland;
Whereby the river's outlet were less free,
Likewise less headlong his descending floods.
It may be, too, that in this season rains
Are more abundant at its fountain head,
Because the Etesian blasts of those northwinds
Then urge all clouds into those inland parts.
And, soothly, when they're thus foregathered there,
Urged yonder into midmost realm of day,
Then, crowded against the lofty mountain sides,
