SYMBOLS - TRIPLE PENTAGRAM - EIGHT TRIGRAMS - SOLAR DISK Symbols from Oswald Wirth, Le Tarot des Imagiers du Moyen Age, 1927. [Top left] A symbol called by Oswald Wirth, the 'triple pentagram', which he links with the Tarot card No. 15 (because of the numerology 3 x 5 = 15). The white pentagram represents the energy of human intelligence. The dark pentagram, which is reversed, represents the darkness within man (exteriorized as the Devil), while the flame-like outer pentagram represents the Divine Spark, the cosmic energy within which Mankind dwells: as Wirth says, it is properly a Glory. [Top right] An arrangement of the eight trigrams of the Chinese Book of Changes, or I Ching, with the Tai Chi in the centre. The Tai Chi represents the ever changing expression of light and darkness (of yang and yin) each of which, of necessity, perpetually changes into the other, in the dance of opposites which is the condition of mutability in the created world. The laws governing this process of change are expressed in the surrounding eight figure (the pa kwa) which contain different conditions of the two basic elements of light and dark. Oswald Wirth does not labour the point, but he suggests a similarity between the Changes of the I Ching, and the changes implicit in the Tarot sequences. [Bottom] The winged solar disk, with the two serpents, associated with the Egyptian god Osiris - Wirth does not ruminate on the meaning of this symbol, but he claims that the two serpents are those found on the hermetic caduceus, and that 'in the eyes of the Hermetists' the entire symbol represents the Philosophic Matter in a state of Sublimation.
