P. Vergilius Maro, Georgics
J. B. Greenough, Ed.

So too, after rain,
Sunshine and open skies thou mayst forecast,
And learn by tokens sure, for then nor dimmed
Appear the stars' keen edges, nor the moon
As borrowing of her brother's beams to rise,
Nor fleecy films to float along the sky.
Not to the sun's warmth then upon the shore
Do halcyons dear to Thetis ope their wings,
Nor filthy swine take thought to toss on high
With scattering snout the straw-wisps. But the clouds
Seek more the vales, and rest upon the plain,
And from the roof-top the night-owl for naught
Watching the sunset plies her 'lated song.
Distinct in clearest air is Nisus seen
Towering, and Scylla for the purple lock
Pays dear; for whereso, as she flies, her wings
The light air winnow, lo! fierce, implacable,
Nisus with mighty whirr through heaven pursues;
Where Nisus heavenward soareth, there her wings
Clutch as she flies, the light air winnowing still.
Soft then the voice of rooks from indrawn throat
Thrice, four times, o'er repeated, and full oft
On their high cradles, by some hidden joy
Gladdened beyond their wont, in bustling throngs
Among the leaves they riot; so sweet it is,
When showers are spent, their own loved nests again
And tender brood to visit. Not, I deem,
That heaven some native wit to these assigned,
Or fate a larger prescience, but that when
The storm and shifting moisture of the air
Have changed their courses, and the sky-god now,
Wet with the south-wind, thickens what was rare,
And what was gross releases, then, too, change
Their spirits' fleeting phases, and their breasts
Feel other motions now, than when the wind
Was driving up the cloud-rack. Hence proceeds
That blending of the feathered choirs afield,
The cattle's exultation, and the rooks'
Deep-throated triumph.
