The youth with secret joy the work surveys,
When now the moon disclos'd her purple rays;
The stars were fled, for Lucifer had chased
The stars away, and fled himself at last.
Soon as the father saw the rosy morn,
And the moon shining with a blunter horn,
He bid the nimble Hours, without delay,
Bring forth the steeds; the nimble Hours obey:
From their full racks the gen'rous steeds retire,
Dropping ambrosial foams, and snorting fire.
Still anxious for his son, the God of day,
To make him proof against the burning ray,
His temples with celestial ointment wet,
Of sov'reign virtue to repel the heat;
Then fix'd the beamy circle on his head,
And fetch'd a deep foreboding sigh, and said,
"Take this at least, this last advice, my son,
Keep a stiff rein, and move but gently on:
The coursers of themselves will run too fast,
Your art must be to moderate their haste.
Drive 'em not on directly through the skies,
But where the Zodiac's winding circle lies,
Along the midmost Zone; but sally forth
Nor to the distant south, nor stormy north.
The horses' hoofs a beaten track will show,
But neither mount too high, nor sink too low.
