Book one of Ovid's Metamorphosis sets a precedence for the rest of the stories in that it illustrates a significant change that either affected human history or one that elaborates on their nature. The difference between the first story and the other stories, however, is that the creation of the Earth was not a changed instigated by punishment or retribution. The story of the four ages begins to describe change, or metamorphosis, less pleasant than the first. The Titans were punished by mother earth for their destruction; Echo is punished by Juno for her using her speech for negative means; Narcissus doomed because he scored admirers.
So in Metamorphosis, change itself is dynamic, first resulting in the act of creation and later in the attempt to reconcile wrongs committed afterward.
