The Pillars of Hercules.
Pike further relates the historical meaning of the two columns Jachin and Boaz, which stand prominently in our lodges; and which each new initiate passes between:
The Solstices, Cancer and Capricorn, the two Gates of Heaven, are the two pillars of Hercules, beyond which he, the Sun, never journeyed: and they still appear in our Lodges, as the two great columns, Jachin and Boaz, and also as the two parallel lines that bound the circle, with a point in the centre, emblem of the Sun, between the two tropics of Cancer and Capricorn.
The Blazing Star in our Lodges, we have already said, represents Sirius, Anubis, or Mercury, Guardian and Guide of Souls. Our Ancient English brethren also considered it an emblem of the Sun. In the old Lectures they said: “The Blazing Star or Glory in the centre refers us to that Grand Luminary the Sun, which enlightens the Earth, and by its genial influence dispenses blessings to mankind.” It is also said in those lectures to be an emblem of Prudence. The word Prudentia means, in its original and fullest signification, Foresight: and accordingly the Blazing Star has been regarded as an emblem of Omniscience, or the All-Seeing Eye, which to the Ancients was the Sun.
