But there is no ground for your charging this work to my account; for you were about to gratify your own craze for fine writing, without a commission from anyone at all. Nay, what am I to offer you not merely to describe Aetna in your poem, and not to touch lightly upon a topic which is a matter of ritual for all poets? Ovid could not be prevented from using this theme simply because Vergil had already fully covered it; nor could either of these writers frighten off Cornelius Severus. Besides, the topic has served them all with happy results, and those who have gone before seem to me not to have forestalled all that could be said, but merely to have opened the way.
