Pythagoras (580-495 B.C.), on the wisdom of the Getae, in his work Moral and Political Laws: “Go to the Getae, not to give them laws, but to learn from them. For the Getae, lands are without borders, all fields are common. And of all the peoples, they are the wisest, Homer tells us”.

Herodotus (484 – 425 B.C.), on Zalmoxis and immortality in the work Histories: The Getae believe themselves immortal in the following manner: they do not believe in death, but that those who disappear from our world join the god Zalmoxis, who is also called Gebeleizis by some among them.

Plato (427 – 347 B.C.), on the medical teachings the Thracian-Getae-Dacians received from Zalmoxis, in the dialogue “Charmides”“(…) Such then, Charmides,is the nature of this charm. I (Socrates – N.N.) learnt it on campaign over there, from one of the Thracian physicians of Zalmoxis, who are said to be able to grant immortality. This Thracian said that (…) Zalmoxis, their king, who is a god, says that as you should not attempt to care for the eyes without healing the head, or the head without the body, so should you not treat the body without also treating the soul, and this is why most maladies evade Greek physicians. They neglect the whole, which should be their main focus, for if the whole is ill then every part of it is afflicted as well. For, he said, all things, good and bad – for the body as well as Man in his entirety – come from the soul, from where they flow (like from a source) from head to eyes. We must then, first and foremost, heal the source of evil so that our head and the rest of our bodies may enjoy full health once more. My friend, he said, the soul heals with charms. These charms are the beautiful words that make wisdom blossom in our souls.”

Strabo (63 B.C. – 21 A.D.), on Zalmoxis, in his work “The Geography: “When he came on back to his home-land he was eagerly courted by the rulers and the people of the tribe, as he could make predictions using celestial signs. At last he persuaded the king to let him rule alongside him, as he was able to relay the will of the gods; at first he [Zalmoxis] was only made a priest of the god who was most honoured in their country, yet after a while he given the title of god, spending his life in a cave only he had the right to enter”.

Emperor Julian the Apostate (331-363 A.D.), citing Emperor Trajan in his work “Kingdoms”: citându-l pe Împăratul Traian în lucrarea Împărații: “The Getae (Dacians) I have defeated were the world’s most valuable warriors, not just because of the strength of their bodies, but because of the teachings of their praised Zalmoxis. Convinced they cannot die, just change their place of residence, they are more willing to face death than some are to face travels”.

Jordanes (6th century A.D.), on Zalmoxis, in his work Getica“In their second halidom, meaning Dacia, Thrace and Moesia, the Goths (Getae – N.N.) had Zalmoxis as king, whom most chroniclers describe as a philosopher with knowledge worthy of admiration.”
