- Persephone was rescued from the Underworld (for a little while) by Hermes, who brought her back to Demeter.
- Eurydice was (almost) rescued from the Underworld by Orpheus.
- Semele was rescued from the Underworld by Dionysus (with the help of Herakles).
- Alcestis was rescued from the Underworld by Herakles, along with a bunch of other people.
It seems to be a common trope (at least in Greek mythology) for souls to be rescued from the Underworld, but only ever by a person or god who is still alive. So I'm curious: do any myths exist anywhere in Greek mythology of souls escaping from the Underworld on their own, or with the help of other dead souls? Any "prison break" myths of souls so slippery they escaped Hades and returned to the mortal world, or else who earn their release through a favor or deal with Hades?
And if not, do any other mythologies in that region (Roman, Egyptian, Phoenician, Sumerian, etc) have myths along those lines? Or was "you can't get out of the Underworld without help" an absolutely ironclad rule?
