Biography
Varro had studied under the Roman philologistLucius Aelius Stilo (died 74 BC), and later at Athens under the Academic philosopher Antiochus of Ascalon (died 68 BC). Varro proved a highly productive writer and turned out more than 74 Latin works on a variety of topics. Aside from his many lost works (known through fragments), two endeavors stand out for historians: Nine Books of Disciplines and his compilation of the Varronian chronology. His Nine Books of Disciplines became a model for later encyclopedists, especially for Pliny the Elder (c. 23 to 79 AD). The most noteworthy portion of the Nine Books of Disciplines is its use of the liberal arts as organizing principles. Varro decided to focus on identifying nine of these arts: grammar, rhetoric, logic, arithmetic, geometry, astronomy, musical theory, medicine, and architecture. Using Varro's list, mediated through Martianus Capella's early-5th century allegory, subsequent writers defined the seven classical "liberal arts" of the medieval schools.
