The Furies are a trio of mythical goddesses known for their vengeful and merciless nature. They are also known as the Erinyes, which means "the avengers" in Greek mythology. Another alternative term for the Furies is the Eumenides, meaning "the kindly ones," a name given to them after they were appeased by the god Apollo. In Roman mythology, they are known as the Furiae or Dirae. The Furies are often associated with death and destruction and are usually depicted as winged women with snakes for hair. They are powerful and feared figures in ancient mythologies, known for their swift and brutal retribution against those who have committed crimes or acted unjustly.
