Some species increase, others diminish, and in a short space the generations of living creatures are changed and, like runners, pass on the torch of life.
LucretiusFrom the heart of this fountain of delights wells up some bitter taste to choke them even amid the flowers.
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.
