Varro may have been a Roman equestrian and served in political office and the military. Although Varro supported Pompey, Caesar pardoned him after the Battle of Pharsalus. Under Augustus Varro wrote a timeline of Roman history referred to as the Varronian chronology.
Varro also wrote Menippean satire, and in connection with this, Quintilian calls Varro the most learned of the Romans (Quintilian Institutio Oratoria Book X).
Much of Varro's work has been lost. Part of his chronology is contained in the Fasti Capitolini and Aulus Gellius included fragments of Varro in his Noctes Atticae. Surviving works of Varro are De lingua latina and Rerum rusticarum. Source: Varro On Agriculture Introduction
