“The Frogs” is a comedic play written by Aristophanes, first performed in Athens in 405 BCE. The play tells the story of the god Dionysus, who is unhappy with the current state of Athenian tragedy and decides to travel to the underworld in order to bring back the great playwright Euripides. Along the way, he meets a chorus of frogs and engages in humorous debates with the philosophers Aeschylus and Euripides over who is the greater playwright.

Through its humorous and often bawdy dialogue, “The Frogs” satirizes the state of Athenian theater, as well as contemporary politics and society. It also explores larger themes of the role of art and the power of words in society. The play’s clever wordplay and witty humor have made it a popular and enduring work of ancient Greek comedy, and it continues to be studied and performed today.
