Summary
Analysis
Ovid explains that he is moved to write about transformations. He asks the gods to help him write a poem that traces history from the creation of the world to the present day.
The two driving forces of the Metamorphoses are transformations and the history of the world. The connection of these two themes suggests that the evolution of history itself is a kind of transformation.
