The Thoth Deck card-key 20-The Aeon, is totally a A.Crowley interpretation of the old tarot card called; THE ANGEL or THE LAST JUDGMENT. In some modern decks it is called JUDGMENT. To Crowley, who wrote a document called THE BOOK OF LAW which he claims was given to him by Angelic means.
This card uses Egyptian mythology to explain its hidden and subtle meanings. We have in the shape of the Omega, the Sky Goddess Nuith along with her consort Hadit who is shown as a golden orb of light. Their union produces Horus, shown both seated and standing as both passive and active forms. Crowley points out that Horus has another name which is Heru and that is synonymous with Hru which is "The Great Angel set over the Tarot." Crowley knew that the system of Tarot evolves to meet the spiritual needs of the races and of that the individual Personality Consciousness and suggest that over time the Spiritual make-up; the Gnosis of mankind, will have so advanced that what was previously known as JUDGMENT, will be inadequate to describe the experience of the Path of Shin . This meets with his assertion that we are now passing through a five hundred year period of extreme darkness and trial,preparatory to a New Aeon of Light. fortunately for all of us, there are many good "Light Bearers" both manifesting as teachers, Gnostic Soul-Personalities and Middle Path Hierophants on Earth and in the Pleroma (higher Astrals known as the "Great White Brotherhood"--because of the White light state of Conscious energy they manifest) that we are assisted in our progress out of this Cultural Dark end of our Era and if aware, can be guided along the road to the New Aeon of Horus---who is the Divine Child of God (Tiphareth) and/or the human body who is becoming the receptacle of the Holy Spirit on Earth. Reinstating our purpose as Spiritual vessels called Souls, to elevate the Survival Mind of Earth to a Higher level of Conscious Energy which we do through the "creating, seeing error, and correcting that error" experience provided by the human body. It is therefore not a far stretch of imagination to see the human being-Spiritual Conscious combination as the New Horus.
In this Aeon card,the Sky Goddess Nuith is a Dark Goddess of Omega---End, signifying the End of the Aeon of Osiris (the Past Aeon) and as we know, energy cannot be destroyed, only transformed, which tells us that ends mean new beginnings. New beginnings are represented by Hadit the Solar Orb of light. The Birth of those beginnings into manifested reality, is Horus both passive and active and/or "in motion and repose." as stated in Gnostic texts. This card represents the harmonious and spiritual conscious state of the human being of the twenty second century. Since we are in this 500 year period of darkness, it is a long slow fall of the Tower, so we must "look inward" to weather the storm. However, we do not have to wait for the 22nd century, as we can become the Divine Child of Universal Energy Conscious inheritance by "knowing Ourselves". We then are no longer bound to the Karmic Wheel of the Human Race and progress forward at our own elevated pace.
The Hebrew letter Shin means Tooth which is descriptive of the Mastication paradigm that is involved with Transformation. This card is worth long meditations on its imagery.
When thrown in a reading, The Aeon means a final decision, Judgment and Sentence. A matter determined without appeal on this material plane.
