an old man whitened by years, who had become wholly white, with a blinding whiteness. His name was Agathodaimon. Turning himself about, the old man with white hair gazed upon me for a full hour.
Jung’s analysis of the Zosimos vision presents the white-haired Agathodaimon as an archetypal senex figure whose absolute whiteness signals both the albedo and the threshold of transformative fire.
