Juvenal has been described as the tabloid of his day and whilst I see the point that is being made, it is a most unfair comparison. He reminded me somewhat of a grumpy old man railing against the corruption, injustice and decadence of the Rome of the time, yet the early satires were apparently written when he was still quite young.
I would not try this without first having read Seutonius or some other such history, because you really do need a basic understanding of the background from which the writes comes, but if you do have a passing knowledge of ancient Rome, you will find some of the observations genuinely funny and satirical.
It's not the most obvious book for a casual reader to pick up, but once into the mindset, I found myself laughing out loud at some of the observations.
