Egkosmioi (Gk). “The intercosmic gods, each of which presides over a great number of daemons to whom they impart their power and change it from one to another at will”, says Proclus, and he adds, that which is taught in the esoteric doctrine. In his system he shows the uppermost regions from the zenith of the Universe to the moon belonging to the gods, or planetary Spirits, according to their hierarchies and classes. The highest among them were the twelve Huper-ouranioi, the super-celestial gods. Next to the latter, in rank and power, came the Egkosmioi.
