The wisdom of the barbarians is much older & stands at the very origins of the Greek one.
Zalmoxe (Zamolxe, in earlier texts) remains one of the most mysterious and powerful spiritual figures of the Dacians. He is best known as their worshipping demigod. Historical sources about the Zalmoxe are few, but I ran into a very complex study of this illuminated character – “Zalmoxis” by Dana Dan (the author’s Ph.D. thesis held at the Ecole des Hautes Etudes en Sciences Sociales in Paris). The book is an ample treatise of all of Zalmoxe’s historical insights. The author resurfaces the known truth and puts into context the exaggerated, misinterpreted or even invented elements which many considered facts.
Thus, by summing up many sources, I can conclude that Zalmoxe was initially an enlightened man, contemporary to many enlightened people of those times (Buddha, Lao Zi, etc.) who have left a deep impression on mankind, following death to reach the stage of a god. Zalmoxe’s impact on current spirituality is inexistent, in contrast to other teachers of his time who I mentioned, one of the reasons being the lack of writing material among the Dacian people. Some sources speak of a set of laws that Zalmoxe held and preached, the Belagine Laws, but their initial form was lost. Coming with this spiritual codex on the territory of the ancient Dacia, he succeeded in organizing and raising people’s spiritual and moral conscience, in return, as a sign of utter respect and gratitude, having been raised to the rank of demigod.
According to one of the etymological alternatives, the word Zalmoxis originates in the word “zalmos”, “bear fur”, meaning the one who was born in a bear fur, as some ancient sources mention. It is supposed that in his youth he has become a disciple of the great philosopher Pythagoras (many sources claiming he was his slave, though I doubt that Pythagoras’ philosophy sustained this practice, perhaps only as first lessons of modesty), being initiated in the secrets the world (spirituality, astronomy, philosophy, mathematics, music, and all the wisdom and harmony that binds them). But if we look at Herodot’s retained and skeptical style, we find that he considered Zalmoxis lived long before Pythagoras (!).
Another historical thread says that after the fire that encompassed Pythagoras’ school in Crotona, Zalmoxe, among the few survivors, migrated to the Celts where he shared with & taught the druids everything he knew. That’s why it’s no wonder the resemblance of the British solar symbols and altar sites to those in our territory. Then he continued his journey into the infusion of his destiny, which seems to have been the spiritual guidance of the Dacians. Zalmoxe is known in history as a legislator, great philosopher, JEAN-BAPTISTE BOURGUIGNON D’ANVILLE having written that “Zalmoxis is like a Tibetan Dalai Lama.”
Unfortunately, his spiritual echo has faded over millennia.
