The Muse Rune is the result of an analeptic download from the Akashic Record, as transmitted to Marcus If while contemplating the evolution of Mnemosyne into a Triad and then an Ennead. Numerous extant esoteric maps overlay the Rune, such as Chakras, the Three Pillars of the OTO, and the Alchemical Union of Opposites. Hidden within the syntax of the Rune are the Boetian Koan and the later Hesiodic Koan, based on the arrangement of the sisters on the Rune. The closest symbol that resembles the Muse Rune is the nuclear Radiation emblem, but that sign does not feature a central triangle. So far research has not discovered this configuration in any semiotic library.
