it could be. the article says it comes from a museum dedicated to pompei

Let's just assume that the way 19th century, Ludwig-II-style museums worked was not exactly historically accurate. This is the king who built Neuschwanstein Castle. He essentially cosplayed as a Roman sometimes, and he built a "Roman villa", more as a holiday home than a museum, and a roman villa needs roman stuff in it. It only became a museum later, half dedicated to the Romans, half to the old king.
