Centauress carrying a bacchante on her back.
From Antiquités d’Herculanum (antiquities of Herculaneum) vol. 1, by Tommaso Piroli, Paris, 1804.
This is further unused research from Purefinder, my debut novel.
[There’s no way I could have included both a representation of a centauress and a bacchante together. Seperate…well, you’d have to read the book to find out.]
