(116 27 BCE) Roman scholar; Varro's intellect led him to study with great teachers in both Athens and Rome; in the civil wars, he sided with Pompey, but was granted a pardon from Caesar; however, after Caesar's assassination, he was politically threatened by Mark Antony so he left Rome; he wrote nearly 500 works and exhibited extensive knowledge.
