I am much interested in the Roman civil war between Caesar and Pompeius. At the moment I am thinking about either reading Aeneis or not. It really depends if it is too difficult for me.Another option would be to read Caesar's De Bello Civili. It can be a bit more complicated than De Bello Gallico, but it can be interesting to study because there's a lot of ways Caesar is kind of twisting the truth or presenting things in a certain way.
