Metamorphoses is a long narrative poem in fifteen books, written in Latin by Ovid and finished around the year 8 CE. It gathers a vast number of myths from Greek and Roman tradition into one continuous story. The unifying subject, stated in the opening lines, is transformation: bodies changing into new shapes. Almost every episode ends with someone or something turned into an animal, a plant, a rock, a body of water, or a star.
The poem opens at the beginning of everything. Out of a shapeless mass called Chaos, where the elements lay in struggle, a creating power separates earth, sea, and sky and gives each its place. Living things fill the world, and finally humankind is formed with a face lifted toward the heavens. The first age is an age of gold, lawless yet innocent, which then declines through harsher ages into violence and the great flood.
From there Ovid moves through cycle after cycle of legend, rarely pausing between stories. The god Apollo pursues the nymph Daphne, who escapes only by becoming the laurel tree. Narcissus wastes away in love with his own reflection while the nymph Echo fades to a voice. The lovers Pyramus and Thisbe die by a shared misunderstanding. Pygmalion's ivory statue is brought to life, and King Midas turns all he touches, even his food, to useless gold. The tales chain together by family, place, or theme rather than by a single plot.
As the poem advances it edges from distant myth toward the world of history. The later books take up the Trojan War, the wanderings of Aeneas, and the founding figures of Rome. Near the close, the philosopher Pythagoras delivers a long speech that draws out the idea behind the whole work: everything in nature is in motion and constantly altering, time itself flows on like a river, and though forms change without end, nothing is ever destroyed. The soul simply passes from one body to the next.
The poem ends in Ovid's own present. Julius Caesar is murdered and then raised to the heavens as a star, and the reign of Augustus is foretold as the world's settled order. In a brief epilogue the poet claims his own kind of immortality, predicting that his verse will outlast bronze and fire and be read wherever Rome's power reaches. The last transformation, fittingly, is the poet himself becoming his enduring name.
