Classics (also Classical Studies) is the study of the languages, literature, laws, philosophy, history, art, archaeology and other material culture of Ancient Greece and Ancient Rome; especially during Classical Antiquity (ca. 600 BCE – 600 CE). Traditionally, the study of Classical literature (Greek and Roman) was the principal study of the humanities.
