I'm not as familiar with the poets or satirists either (hence the eager desire for discussion)! Although Juvenal is considered a 'non-historian', his words certainly provide an interesting insight into the world of Rome- it's social life, everyday sights and sounds and physical features. Indeed, Juvenal was probably a jaded man, but perhaps this bias reflects some kind of truth in that many people of that time were probably feeling similar jaded sentiments. Apparently Juvenal was incredibly poor for a lot of his life and experienced the patron-client relationship he vehemently abhors in his writings.
As a student of history, this is one thing I grapple with- the idea of 'non-history' and 'history.' A lot of sources offer a lot of historical value- even if they were never intended to do so. I guess that's why we must be careful to include sources such as Juvenal and Martial in our historical endeavours- they provide a unique voice that is often much needed. For example, Juvenal's well known phrase 'breads and circuses' is well worth noting when discussing the pomp and propaganda that emperors such as the Flavians used in their public festivities.
Well, it's 2.15am for me here in Australia and I'm rambling in a very bad way. Off to bed. Cheerio.
