Mysteria

"Mysteria" by Otto Henne am Rhyn is a historical study written in the late 19th century. It surveys esoteric doctrines, temple mysteries, and secret orders from antiquity to modern times, explaining their rites, symbols, aims, and social influence in a unified comparative narrative. The opening of the work frames humanity’s enduring fascination with the hidden, arguing that curiosity, fear, and ambition give rise to mysteries and to secret societies that pursue power, reform, charity, art, or even destruction. A translator’s note outlines the book’s sweep—from Egyptian and Greco-Roman rites through medieval orders to Freemasonry and the Illuminati—praising the author’s synthesis. The first chapters trace religion’s roots in the personification of nature and show how priests reserved rational, allegorical interpretations for initiates while the populace kept literal myths. A substantial section on Egypt covers priestly and warrior castes, an astronomy-based cult, animal symbolism, the rise of solar theology (Re, Horus, Osiris), Akhenaten’s Aten reform and its reversal, beliefs about the soul (ka, ba), judgment after death, and a likely monotheistic core taught in secret. Brief surveys of Babylonia/Assyria (Sumerian–Semitic blend, planetary gods, priest-astronomers, creation and flood epics, Istar’s descent), Persia (Zoroastrian priestly dominance and dualism), and India (Brahman pantheism, popular polytheism, Buddhist reform and later esoteric turns) follow, along with examples of secret leagues among so‑called “barbarous” peoples. The narrative then turns to Greece—adogmatic civic worship, seers and oracles, and the inward, un‑Hellenic cast of the mysteries—leading into the Eleusinian cult’s myth (Demeter–Persephone) and the structure of its festivals and processions, where the excerpt breaks off.
