Roman Literature:

Varro

Marcus Terentius Varro (116 - 27 BC) was a great Roman scholar with academic achievement in many fields. He studied under the philogist Lucius Aelius Stilo and the philosopher Antiochus. Of equestrian birth and rank, Varro was a supporter of Pompey in the civil wars at the fall of the republic, and even served as a legate at the battle of Pharsalus. He was pardoned by Caesar and actually promoted to direct the public library in Rome, in light of his prolific writing.

After the death of Caesar, however, politics took a significant turn in his life, and Varro was proscribed by Marc Antony, having his villa confiscated and forced to flee for safety. After Octavian's victory at Actium and the establishment of artistic enlightenment in Rome, Varro returned and continued his writing on a vast number of subjects. In all, it's been estimated that he wrote up to 620 separate volumes.
