Then cities were not girt with massive walls,
With frequent towers set; no soldier there
To savage arms his hands applied, nor burst
The close-barred gates with huge and heavy stones
From ponderous engines hurled. As yet the earth535
Endured no master's rule, nor felt the sway
Of laboring oxen yoked in common toil;
But all the fields, self-fruitful, fed mankind,
Who took and asked no more. The woods gave wealth,
And shady grottoes natural homes supplied.
