The Euripides described by ancient biographers is the Euripides Aristophanes portrays in the comedies he wrote for Athenian audiences after the devasting plague of 430–429 BC: immoral, sophistic, and irreligious. Biographers created new anecdotes about him, using the comic poets’ techniques, taking lines from his dramas out of their original contexts and placing them in anecdotes in which they could be repurposed to express his personal thoughts. The process of transforming literature into biography can be seen most clearly in the Life of Euripides by the Hellenistic biographer Satyrus, which is based almost entirely on anecdotes created to provide new contexts for some of Euripides’ most memorable lines; for example, an account of Euripides’ death mirrors the account of Pentheus’ death in Euripides’ drama Bacchae. The idea that Euripides was critical of ancient religion, like some famous philosophers, explains why Diogenes Laertius refers to Euripides more frequently than any other poet. These ancient characterizations continue to have a profound and misleading influence on modern interpretation of his dramas, demonstrating how transformative an effect a skillful comic poet can have on the course of literary history.
