Which 2? History of Rome is great. The Fall of the Roman Empire is neat because it's a bit more academic, but still quite interesting.
Gibbon's work is great, but clearly quite biased and gets a bunch of the 'barbarian invasion' stuff wrong. I only had the 1 volume version. Did you read the whole damn thing?
Yep did the whole thing. I actually considered it a much more subtle examination of the dynamics between Rome and the Goths/Huns/Alamanni/Vandals/etc than some histories. I had known Aleric was a Roman general, but was unaware of how long the Huns had been in the region as both an ally and a threat prior to Attila. Seems for many, the main complaint is how much blame for the fall he seems to place on the rise of Christianity. He certainly was intrigued by Roman paganism.
Shirer's books are great. 'Rise and Fall' is epic, but 'Berlin Diaries' is also worth reading as more more focused first hand account of Germany slowly descending into Naziism during the 30s.
