Zalmoxis (Greek Ζάλμοξις, also known as Salmoxis, Σάλμοξις, Zamolxis, Ζάμολξις, or Samolxis, Σάμολξις) is a divinity of the Getae, mentioned by Herodotus in his Histories IV, 93-96. In later interpretations, which begin with Jordanes (6th century AC) and have proliferated during the 19th and 20th century, mainly in Romania, he was regarded as the sole god of the Getae (not to be confounded in this context with the Thracians or their relatives, the Dacians) or as a legendary social and religious reformer of the Getae people to which he would have taught, following Herodotus, the belief in immortality, so that they considered dying merely as going to Zalmoxis. Herodotus states that Zalmoxis was also called by some of the Getae Gebeleizis, which made some searchers conclude that Getae were actually henotheists or even polytheists. Another discussion exists about the chthonic, infernal, or uranian, heavenly, character of Zalmoxis.
