Euripides was a key figure in the development of ancient drama, and the continuing impact of his work on modern forms of theatre cannot be underestimated. His tragedies were dramaturgically innovative and intellectually challenging. Divine epiphanies, emotionally charged debate scenes, and novel musical performances are all typical in Euripides. Several of his plays exploit the sort of disaster-averted scenario that was one of Aristotle’s favourite plot types and that flourished in operatic adaptations of classical myths. Pointed theological and philosophical questions are raised by characters in Euripides’ plays, and this radical aspect of Euripidean drama explains both why he was a target for contemporary comedians, notably Aristophanes, and why he was dismissed by Nietzsche and others in the nineteenth century. The past century, however, has seen a renewed and reinvigorated appreciation for Euripides, whose dramas have provided a valuable medium not only for artistic expression and experimentation but also for engaging with pressing contemporary social and political issues such as racial discrimination, warfare, postcolonialism, gender fluidity, and PTSD.
