The figure of the cordial host of the Academy, who invited the most gifted mathematicians and cultivated pure research, whose keen intellect was able if not to solve the particular problem then at least to show the method for its solution: this figure is quite familiar to students of Greek science. But was the Academy as such a center of scientific research, and did Plato really set for mathematicians and astronomers the problems they should study and methods they should use? Our sources tell about Plato's friendship or at least acquaintance with many brilliant mathematicians of his day (Theodorus, Archytas, Theaetetus), but they were never his pupils, rather vice versa -- he learned much from them and actively used this knowledge in developing his philosophy. There is no reliable evidence that Eudoxus, Menaechmus, Dinostratus, Theudius, and others, whom many scholars unite into the group of so-called "Academic mathematicians," ever were his pupils or close associates. Our analysis of the relevant passages (Eratosthenes' Platonicus, Sosigenes ap. Simplicius, Proclus' "Catalogue of geometers", and Philodemus' "History of the Academy", etc.) shows that the very tendency of portraying Plato as the architect of science goes back to the early Academy and is born out of interpretations of his dialogues

Apart from his teachings, wonders and scientific discoveries, Pythagoras was also known for his wide-ranging journeys. Ancient authors alleged that he visited many countries and nations from Egypt to India, stayed with the Phoenicians and the Ethiopians and talked to the Persian Magi and Gallic Druids. However, he never went to the North. If, nevertheless, he was eventually associated with the northern inhabitants, it is only because they themselves came into close contact with him. The first of them was Zalmoxis, a deity of a Thracian tribe, the Getae, who guaranteed them immortality after death. Having described a blood ritual that the Getae practised to become immortal, Herodotus relates a story he heard from the Hellespontine and Pontic Greeks. It goes that Zalmoxis was not adaimōnbut a former slave of Pythagoras on Samos and, having adopted the doctrine of immortality from him, he returned to Thrace and converted his tribesmen to it with a cunning trick. He invited the most prominent of them to a men's hall for entertainment and told them that neither he nor they or their descendants would die, but would live eternally. Then, having constructed a secret underground chamber, he suddenly disappeared from the eyes of the Getae and hid in his shelter for three full years, being lamented as dead. Then he showed himself again to the Getae, thus persuading them of the truth of his promises.
