The underworld is made up of four vestibules and three hells properly so called. The vestibules have each two rulers, Zartay and Zartanay, Hag and Mag, Gaf and Gafan, Anatan and Kin. In the highest hell rules alone the grisly king Sh'dum, "the warrior"; in the storey immediately beneath is Giv, "the great"; and in the lowest is Krun or Karkum, the oldest and most powerful of all, commonly called "the great mountain of flesh" (_Tura rabba d'besra_), but also "the first-born of darkness." In the vestibules dirty water is still to be met with, but the hells are full of scorching consuming fire, except Krun's domain, where is nought but dust, ashes and vacancy. Into these regions descended Hibil the brilliant, in the power of _Mana rabba_, just as in the Manichaean mythology the "primal man," armed with the elements of the king of light, descends to a contest with the primal devil. Hibil lingers, gradually unfolding his power, in each of the vestibules, and finally passing from hell to hell reaches Karkum. Hibil allows himself to be half swallowed by the monster, but is unhurt, and compels his antagonist to recognize the superiority of _Mana rabba_, the God of light, and to divulge his profoundest secret, the hidden name of darkness. Armed with this he returns through the successive hells, compelling the disclosure of every secret, depriving the rulers of their power, and barring the doors of the several regions. From the fourth vestibule he brought the female devil Ruha, daughter of Kin, and set her over the whole four. This Ruha, the mother of falsehood and lies, of poisoning and fornication is an anti-Christian parody of the Ruha d'Qudsha (Holy Spirit) of the Syriac Church. She is the mother of Ur, the personified fire of hell, who in anger and pride made a violent onset on the world of light (compare the similar occurrence in the Manichaean mythology), but was mastered by Hibil and thrown in chains down to the "black water," and imprisoned within seven iron and seven golden walls. By Ur, Ruha, while P'tahil was engaged in his work of creation, became mother of three sets of seven, twelve and five sons respectively; all were translated by P'tahil to the heavenly firmament (like the Archons of Mani), the first group forming the planets and the next the signs of the zodiac, while the third is as yet undetermined. Of the names of the planets Estera (Ishtar Venus, also called Ruha d'Qudsha, "holy spirit"), Enba (Nebo, Mercury), Sin (moon), Kewan (Saturn), Bil (Jupiter), and Nirig (Nirgal, Mars) reveal their Babylonian origin; Il or Il Il, the sun, is also known as Kadush and Adunay (the Adonai of the Old Testament); as lord of the planetary spirits his place is in the midst of them; they are the source of all temptation and evil amongst men. The houses of the planets, as well as the earth and a second world immediately to the north of it, rest upon anvils laid by Hibil on the belly of Ur.
