Aeon418
On the theme of Crowley not having everything worked out with regard to the Aeon of Horus, a good example can be found in the Thoth deck itself. The Aeon card.
Following the example set by the traditional Judgement card, the Aeon should really show the end of the Aeon of Horus. But Crowley says in The Book of Thoth:
Maybe this is something that Crowley was unsure about. He certainly argued with Frater Achad on this point. Achad thought Hrumachis was Har-Makhu, Horus of two Horizons (east and west). Crowley's final words in the above quote suggest he might have had second thoughts about Achad's ideas.

In his commentaries on The Book of the Law, Crowley says that the next Aeon is that of Maat. Probably because Maat (Libra) is the next god after Horus in a Golden Dawn temple. But Hrumachis suggests another form of Horus combined with Maat. Hru (Horus) machis (Maat).Behind this letter is a symbolic representation of the Sign of Libra; this is the forth-shadowing of the Aeon which is to follow this present one, presumably in about 2,000 years - "the fall of the Great Equinox; when Hrumachis shall arise and the double-wanded one assume my throne and place". The present Aeon is too young to give a more definite representation of this future event. But in this connection attention must be drawn to the figure of Ra-hoor-khuit: "I am the Lord of the Double Wand of Power; the wand of the Force of Coph Nia; but my left hand is empty, for I have crushed an Universe; and nought remains."
