Iao (Gnostic) A three-letter mystery-name, parallel in one sense with the Sanskrit pranava, and reminiscent of triune deities represented by a triplicity of sounds. It occurs in many variations: Io, the Grecian moon goddess; Iaho, Jevo, Jehovah, and other Hebraic forms; Iaso, the possible origin of the name Jesus; Iacchos, the Bacchus of the Mysteries. It is at once threefold, fourfold, and sevenfold in meaning.
Iao Hebdomad (sevenfold) was one of the septenary mystery-gods of the Gnostics, given by Origen as the regent of the moon. The Gnostics had a superior hebdomad, an inferior or celestial one, and the terrestrial one. Iao was regarded as the chief of the superior seven heavens above the earth and is identical with the chief of the lunar pitris (SD 1:448).
Again, Iao Hebdomad is the septenary Iao or the collective seven cosmic rectors, each one representing a heaven, and therefore identifying this Iao Hebdomad at once with the seven mystery-planets of the ancients. Iao, sometimes connected with Yaho, from another standpoint is the collective seven or ten classes of the manasaputras. It is also connected with the Chaldean heptakis. Thus Iao or Iao Hebdomas, according to the point of view, is not only the septenary groups of the lunar dhyanis or pitris, but likewise the seven or ten groups of the manasaputras.

Yah, Yaho 'yahu, yeho (Hebrew) Yah is an abbreviation of Jehovah, but equally well Jehovah could be said to be merely an enlargement of the original form Yah. The Zohar says that the 'Elohim used this word to form the world.
"To screen the real mystery name of ain-soph -- the Boundless and Endless No-Thing -- the Kabalists have brought forward the compound attribute-appellation of one of the personal creative Elohim, whose name was Yah and Jah, the letters i or j or y being interchangeable, or Jah-Hovah, i.e., male and female; Jah-Eve an hermaphrodite, or the first form of humanity, the original Adam of Earth, not even Adam-Kadmon, whose 'mind-born son' is the earthly Jah-Hovah, mystically. And knowing this, the crafty Rabbin-Kabalist has made of it a name so secret, that he could not divulge it later on without exposing the whole scheme; and thus he was obliged to make it sacred" (SD 2:126).
Both Yah and Yaho were Hebrew mystery-names; Yah is "a later abbreviation [of Yaho] which, from containing an abstract ideal, became finally applied to, and connected with , a phallic symbol -- the lingham of creation" (TG 374). Thus Yaho and Yah are two forms of the same original Shemitic god-name found throughout Asia Minor, and which appeared in its Greek form as Iao. The Gnostics revived the Chaldean and Phoenician mystery-god Iao, placing it above the seven heavens as representing spiritual light. Its ray was nous, standing for the Demiurge as well as the divine manas.
