“There is nothing constant in the universe, all ebb and flow, and every shape that is born bears in its womb the seeds of change” (Metamorphoses 5.177)

“Believe me, nothing perishes in all the world; it does but vary and renew its form. What we call birth is but a beginning to be other than what one was before; and death is but a cessation of a former state” (Metamorphoses 15. 254-257)
