Allegory of the Cave
Plato (428/427–348/347 BCE) presented accounts of reincarnation in his works, particularly the "Myth of Er", where Plato makes Socrates tell how Er, the son of Armenius, miraculously returned to life on the twelfth day after death and recounted the secrets of the other world. There are myths and theories to the same effect in other dialogues, in the Chariot allegory of the "Phaedrus", in the "Meno", "Timaeus" and "Laws". The soul, once separated from the body, spends an indeterminate amount of time in "formland" (see The Allegory of the Cave in "The Republic") and then assumes another body.
