Geetings. I was going through my book case and I found a book i hadn't looked at in quite sometime and I ran across..."a dictionary of SYMBOLS" by J.E. Cirlot, translated from the original Spanish.
In the book I found this on Gems and the Zodiac...
"...The aerolite, in particular, because of its connexion [sic] with the celestial sphere, represents the mansion ad the vestments of a god descended upon Earth. Shooting stars are related to angels. there is another traditon which imparts an infernal shade of meaning to the precious stone, by reason of the 'obscure' naure of the knowledge which it connotes. Plainly, in this case it is the feeling of aversion towards the material richness of the stone that prevails over-or is allied with- admiration for its hardness, colour and transparency. In this connexion [sic], Baron Guiraud, in La Philosophie de l'historie, comments that, when Lucifer fell, angelic light was given corporeal form in the shining stars and glittering gems. Jewels have also been equated with metals, as a kind of 'subterranean astronomy' and in fact, though the application of the theory of correspondences, with every other order of existence. All kinds of glistening specks of colour, too, may contain some of the symbolic sense of particular precious stones, but only as secondary meanings and by association with the essential symbolic significance of jewels and made use of it in their liturgy. Levi, in Les mysteres du Rational d'Aaron, recalls that 'The Rational, consisting of twelve precious stones [representing the twelve months of the year, and the signs of the Zodiac], was arranged as four lines with three stones in each, and the type and colour of the stones, from left to right and from top to bottom were: sardonyx [red], emerald [green], topaz [yellow], ruby [red tending to orange], jasper [deep green] sapphire [deep blue], jacinth [lilac], amethyst [violet], agate [milky], chrysolite [golden blue], beryl [darkish blue], and onyx [pink]. Each one of these stones had a given magic ability. The order in which they appear is based upon their colour and luminosity, decreasing, as in a tongue of flame, from top to bottom and from outside to the centre. [sic]"
