According to Strabo, Zalmoxis was a prophet who exhorted the wise and noble devotees to live according to their written laws, called the Belgian Laws.
He also taught them logic, physics, theology, ethics, and astronomy, helping them to develop a level of reasoning that was very advanced for its time. This kind of active pursuit is most likely at the heart of the name Getae, which is derived from the word “goetes” or, meaning prophets.
