Time Period

The chart above provides a rough idea of the time period when The Frogs was written. The Frogs was written in approximately 405 BC. This is near the end of the Pelopnisian Wars, a fact made clear in the script. In the same year the Frogs was written the Athenians lost the last of their once grand fleet. The Frogs comes out at a time of desperation in Athens, when the threat of Sparta looms large over the city. It is also important to bear in mind that Euripedes has just recently died, within the last year. The morale of Athens has been crushed and it needs all the laughs it can find.
