I hoped when I read the headline that they had found an actual legion eagle, but it’s a representation.

I disagree with the museum’s interpretation: the snake did not represent evil to the Romans, who did not even have a Christian concept of evil. It represented the earth, rebirth, and the realm of the dead. The eagle is the bird of Jupiter, and Jupiter Tonans (Jupiter of the Thunder) is the god at the crest of the Capitoline, the capitolium of Rome. It represents Rome overcoming the forces of the earth, or as we would see it, the sky and the forces of civilization overcoming the chaos and darkness of the world-below, ie, the disorder.
