and Thuella (Storm), guard it; there Zeus banished any of the gods whenever one behaves with insolence." Thus the identity between Zeus' prison-house and the pentemychos seems likely. Judging from some ancient fragments Ophion is thrown into Oceanus, not into Tartaros. Exactly what entities or forces that were locked away in Pherecydes’ story cannot be known for sure. There may have been five principal figures. Ophion and Typhon are one and the same, and Eurynome fought on the side of Ophion against Cronus. Chthonie is a principal "thing" of the underworld, but whether she is to be counted as one of the five or the five "sum-total" is an open question. Apart from these it is known that Ophion-Typhon mated with Echidna, and that Echidna herself was somehow mysteriously "produced" by Callirhoe. If Pherecydes counted five principal entities in association the pentemychos doctrine, then Ophion, Eurynome, Echidna, Calirrhoe and Chthonie are the main contenders. Legacy Pherycydes is seen as a transitional figure between the mythological cosmogonies of Hesiod and the first pre-Socratic philosophers. Aristotle wrote in his Metaphysics that Pherecydes was partially a mythological writer and Plutarch, in his Parallel Lives, instead wrote of him being a theologian. Pherecydes contributed to pre-Socratic philosophy of nature by denying that nothing comes from nothing and describing the mixture of three elements. Mixture (krasis) plays a role in later cosmologies, such as that of Anaxagoras, Plato (Timaeus) and in the Orphic poem Krater attributed to the Pythagorean philosopher Zopyrus of Tarentum. Pythagoreanism Out of all of the philosophers who were historical predecessors of Pythagoras, Pherycydes was the philosopher most often linked with him as one of his teachers. Not many prose treatises existed in the 6th century, Pythagoras may have learned of Pherecydes' work and adopted the idea of ​​reincarnation. In Pythagoras' youth, when he still lived on Samos, he is said to have visited Pherecydes on Delos and later buried him. An early variant of this story places this event later in Pythagoras' life when he lived in Croton. His visit to the sick Pherecydes was used to explain his absence during Cylon's rebellion in that city. These stories may have evolved from the story that Pythagoras was a student of Pherecydes. According to Apollonius, Pythagoras imitated Pherecydes in his 'miracles'. The historicity of the connection between the two has been debated, however, because their philosophies are otherwise unrelated, and because Pythagoras
