In Greek mythology, Poena (also Poine) is the spirit of punishment[1] and the attendant of punishment to Nemesis,[2] the goddess of divine retribution. Her Roman equivalent may have been Ultio. The Latin word poena, "pain, punishment, penalty", gave rise to English words such as subpoena and pain.[3] The original word is the Ancient Greek poinḗ (ποινή), also meaning penalty. Poena was also treated as a host of spirits called poenai that were similar in nature to the Erinyes.
