Lucretius, De Rerum Natura
William Ellery Leonard, Ed.

     And now what cause
Hath spread divinities of gods abroad
Through mighty nations, and filled the cities full
Of the high altars, and led to practices
Of solemn rites in season- rites which still
Flourish in midst of great affairs of state
And midst great centres of man's civic life,
The rites whence still a poor mortality
Is grafted that quaking awe which rears aloft
Still the new temples of gods from land to land
And drives mankind to visit them in throngs
On holy days- 'tis not so hard to give
Reason thereof in speech. Because, in sooth,
Even in those days would the race of man
Be seeing excelling visages of gods
With mind awake; and in his sleeps, yet more-
Bodies of wondrous growth. And, thus, to these
Would men attribute sense, because they seemed
To move their limbs and speak pronouncements high,
Befitting glorious visage and vast powers.
And men would give them an eternal life,
Because their visages forevermore
Were there before them, and their shapes remained,
And chiefly, however, because men would not think
Beings augmented with such mighty powers
Could well by any force o'ermastered be.
And men would think them in their happiness
Excelling far, because the fear of death
Vexed no one of them at all, and since
At same time in men's sleeps men saw them do
So many wonders, and yet feel therefrom
Themselves no weariness. Besides, men marked
How in a fixed order rolled around
The systems of the sky, and changed times
Of annual seasons, nor were able then
To know thereof the causes. Therefore 'twas
Men would take refuge in consigning all
Unto divinities, and in feigning all
Was guided by their nod. And in the sky
They set the seats and vaults of gods, because
Across the sky night and the moon are seen
To roll along- moon, day, and night, and night's
Old awesome constellations evermore,
And the night-wandering fireballs of the sky,
And flying flames, clouds, and the sun, the rains,
Snow and the winds, the lightnings, and the hail,
And the swift rumblings, and the hollow roar
Of mighty menacings forevermore.
