LucretiusMany animals even now spring out of the soil, Coalescing from the rains and the heat of the sun. Small wonder, then, if more and bigger creatures, Full-formed, arose from the new young earth and sky. The breed, for instance, of the dappled birds Shucked off their eggshells in the springtime, as Crickets in summer will slip their slight cocoons All by themselves, and search for food and life. Earth gave you, then, the first of mortal kinds, For all the fields were soaked with warmth and moisture.

LucretiusAnd part of the soil is called to wash away In storms and streams shave close and gnaw the rocks. Besides, whatever the earth feeds and grows Is restored to earth. And since she surely is The womb of all things and their common grave, Earth must dwindle, you see and take on growth again.
Lucretius
