Ancient Greek literatureAncient Greek literature is literature written in the Ancient Greek language from the earliest texts until the time of the Byzantine Empire. The earliest surviving works of ancient Greek literature, dating back to the early Archaic period, are the two epic poems the Iliad and the Odyssey, set in an idealized archaic past today identified as having some relation to the Mycenaean era. These two epics, along with the Homeric Hymns and the two poems of Hesiod, Theogony and Works and Days, constituted the major foundations of the Greek literary tradition that would continue into the Classical, Hellenistic, and Roman periods.
