is there a novel about her yet?

Thanks to Mary Beard, I now know about Allia Potestas, a Roman freedwoman who, round about the 2nd or 3rd century CE, lived in happy harmony with her two lovers. One of them wrote this epitaph that was carved on her memorial stone. There's a nice image of the stone here about halfway down.

How I wish that, back when I was trying to learn Latin, the textbook had given me more of this kind of thing and less about stern manly virtues.
