What attracts you to Late Rome?

[Timianus]

Sure but it wasn't so much a religion as a kind of patriotic or civic duty. IIRC all it involved was a small sacrifice like pouring out a libation.

The two were one and the same! It also involved recognizing the Princeps as the ultimate authority on all matters through the combination of his authority as pontifex maximus and consular imperium. Christians refused to do this.
