Steiner relates that Hermes, the great teacher of the Egyptian Mysteries, was a disciple of Zarathustra reborn bearing his master's astral body, carrying Persian Sun wisdom into Egypt.
Hermes and the Zarathustra Stream in Anthroposophy is Rudolf Steiner's account of how the great teacher of the Egyptian Mysteries received the preserved astral body of Zarathustra, the ancient Persian initiate. In The Principle of Spiritual Economy (GA 109, 1909), Steiner relates that Zarathustra had two intimate disciples; to one he imparted everything that can be perceived with clairvoyant astral organs, and this disciple was reborn as Hermes, the Egyptian Hermes, wearing his teacher's sacrificed astral body as if it were a garment. Equipped with that sheath, Hermes inaugurated the third post-Atlantean culture and carried the Persian Sun wisdom of Ahura Mazdao into Egypt, while his fellow disciple Moses received the etheric body. Readers meet this Hermes again wherever the Hermetic tradition is studied, from the Corpus Hermeticum to Marsilio Ficino's Florentine translation of 1463.
Among the figures Steiner traces through GA 109, Hermes and the Zarathustra Stream names the moment Persian initiation wisdom crossed into Egypt. A favoured disciple of Zarathustra, trained to see with the organs of the astral body, was reborn as the sage of the Egyptian Mysteries. At his birth the master's own astral sheath was laid about him, and the temple culture of the Nile took its direction from what he proclaimed.
In Steiner's Own Words
The first disciple was reincarnated as the great individual who was to inspire and inaugurate the new currents of Egyptian culture, the being whom we know by the name of Hermes or Hermes Trismegistos. Through processes that are known, the astral body of Zarathustra was transmitted to Hermes so that he could proclaim the message of the higher worlds and their mysteries and incorporate them into Egyptian culture. Thus by processes we will gradually learn to understand, the astral body of Zarathustra was preserved and was transmitted to one disciple when he was born again as Hermes. Hermes wore Zarathustra's astral body as if it were a garment.
What it Means Today
European esotericism has honoured Hermes Trismegistus as the fountainhead of all wisdom at least since 1463, when Cosimo de' Medici asked Marsilio Ficino to set Plato aside and translate the newly recovered Corpus Hermeticum first. Steiner reads the legend from the opposite bank. In GA 109 the Egyptian sage is not a fountainhead but an inheritor: the wisdom the Nile temples revered as primordially their own had ripened in Persia, inside the astral sheath of Zarathustra, and crossed into Egypt through a death, a rebirth, and a gift. Where the Renaissance imagined a chain of texts running out of Egypt into Greece, Steiner describes a chain of bodies, and Hermes stands as its first Egyptian link. That reversal is the distinctly anthroposophical contribution to Hermetic studies, and collections such as the Bibliotheca Philosophica Hermetica, assembled in Amsterdam by Joost Ritman from 1957 onward, preserve the long afterlife of the legend whose prehistory Steiner's Munich lecture of 7 March 1909 lays bare.
A reader can test the claim directly. Open the Poimandres, where Hermes receives a vision of boundless light from the divine Nous, beside Zarathustra's proclamation of Ahura Mazdao, the great aura of the Sun. The family resemblance between the two Sun revelations is what GA 109 would lead one to expect, since on Steiner's account the second teacher saw with organs the first had prepared, and proclaimed in Egypt what he had once learned in Persia.
