Metamorphoses in Greek mythology

In ancient Greece, the surviving Greek mythology features a wide collection of myths where the subjects are physically transformed, usually through either divine intervention or sorcery and spells. Similar themes of physical transformation are found in all types of mythologies, folklore, and visual arts around the world, including those of Mesopotamian, Roman (Ovid's Metamorphoses), medieval (Western Christian), and ancient Chinese.
