Tacitus  
The Annals of Imperial Rome
TIPS FOR READERS

The Penguin edition
with translation from
Michael Grant is
inexpensive, easy to
find, and very well
done.
Focusing on the Roman empire following the death of Caesar
Augustus, especially the reigns of Tiberius and Nero, Tacitus
presents a profound and dispiriting inquiry into the collapse of
democratic values.  The corrupting influence of power, the
degradation and impotence of the Senate and other democratic
institutions, the sycophancy and intrigues and decadence -- all
these are probed with unflinching honesty by the great
historian.  In a better world, this work would be required
reading for all politicians, a cautionary tale with too much
relevance for our modern lives.

works along with a refutation of the claim that the historian's
writings were forged in by Poggio Bracciolini in the 14nth
century.
