Aeon of Isis The first Aeon, of Isis, was maternal. The female aspect of the Godhead was revered due to a mostly
matriarchal society and the idea that "
Mother Earth" nourished, clothed and housed man closed in the womb of Matrix. It was characterised by
pagan worship of the
Mother and
Nature. In
The Equinox of the Gods, Crowley describes this period as "simple, quiet, easy, and pleasant; the material ignores the spiritual."
Lon Milo DuQuette wrote that this aeon was "the Age of the Great Goddess", tracing its origin to prehistory and identifying its zenith around "approximately 2400 B.C." In doing so, he was drawing upon the hypotheses of early 20th-century archaeologists such as
Sir Arthur Evans, whose work at Knossos suggested a prehistoric, matriarchal, goddess-centered religion. Continuing in this vein, DuQuette described the period as one in which the hypothetical cult of the
Great Goddess—a unifying figure behind many goddesses across diverse cultures—would have been truly universal and worshipped under myriad names and forms across the ancient world. However, DuQuette cautions against assuming that the magical formula of this aeon manifested solely through the worship of any specific anthropomorphic female deity. He explains: "Like every aeon, the magical formula of the Aeon of Isis was founded upon mankind's interpretation of the 'perceived facts' of nature, and our Isian-age progenitors perceived nature as a continuous process of spontaneous growth."
Aeon of Osiris According to Crowley, the
classical and
medieval Aeon of Osiris succeeded the Aeon of Isis and marked a shift from matriarchal, nature-based spirituality to a patriarchal religious structure centered on
moral dualism,
self-sacrifice, and submission to the
Father God. Crowley identified
Osiris as the archetype of the
slain god, whose death and
resurrection formed the theological foundation for many religions of the period, including
Christianity. During this aeon, spiritual truth was seen as external and transcendent, mediated by priesthoods and scriptures. The individual was perceived as a fallen being, requiring
redemption through obedience, suffering, or sacrificial rites. He characterized this period as emphasizing the solar father figure, contrasted with the lunar mother of the Aeon of Isis, and anticipated its end with the birth of a new aeon focused on the divine child, Horus. The occultist
Kenneth Grant later elaborated on Crowley's framework, interpreting the Aeon of Osiris as an era of spiritual concealment in which esoteric knowledge was systematized, ritualized, and obscured beneath layers of dogma. He emphasized that the dismemberment of Osiris symbolized a fragmentation of primordial wisdom, and regarded the aeon as dominated by reflective, lunar consciousness rather than direct initiatory experience. In his view, the transition to the Aeon of Horus marks a return to more immediate, transformative modes of spiritual engagement.
Aeon of Horus The Aeon of Horus, identified by Crowley as beginning in 1904 with the reception of
The Book of the Law, marks the current era in Thelemic philosophy. This aeon emphasizes
self-realization,
individualism, and the pursuit of one's
True Will, symbolized by the child god Horus representing new beginnings and potential growth. Crowley described it as a time of the Crowned and Conquering Child, focusing on spiritual awakening and personal freedom. He also stated, "every man and every woman is a star", highlighting the unique and divine nature of each individual. Key figures such as Israel Regardie and Kenneth Grant highlight the transformative nature of this aeon, encouraging individuals to embrace their True Will and move beyond previous constraints. Regardie saw it as a shift towards new spiritual and psychological paradigms, while Grant emphasized the break from the restrictions of prior aeons. DuQuette elaborates on the Aeon of Horus as a period of growing individual consciousness and the realization of one's spiritual potential, contrasting it with the
Age of Aquarius, which he sees as a smaller aspect of a greater spiritual age. Gunther interprets the Aeon as a time of significant spiritual evolution, driven by the awakening of individual consciousness and the unfolding of the True Will. The Thelemic calendar uses a unique dating system incorporating Tarot trumps and astrological positions, aligning significant events with corresponding Tarot cards and the positions of the Sun and Moon, reflecting the Thelemic emphasis on synchronizing personal and cosmic cycles. Crowley detailed the practice of recording magical work in his writings on the magical record, emphasizing the importance of documenting spiritual progress.
Aeon of Ma'at Aleister Crowley believed that the Aeon of
Ma'at will succeed the present one. However, Crowley suggested that the succession of the aeons is not bound to the
axial precession of the equinoxes in his 'Old Comment' to Liber AL chapter III, verse 34, where he states, "Following him [Horus] will arise the Equinox of Ma, the Goddess of Justice, it may be a hundred or ten thousand years from now; for the Computation of Time is not here as There." According to one of Crowley's early students,
Charles Stansfeld Jones (a.k.a. Frater Achad), the Aeon of Ma'at has already arrived or overlaps the present Aeon of Horus. Crowley wrote: ==See also==
