From metamorphism to metamorphosis, there is only a shade of a nuance. Because metamorphic rocks are not only what they are, but also what they were, and they tell of what happened in between. What must be discovered: how to recognize in the butterfly, the caterpillar that was, or in the caterpillar the butterfly that will be?
