This unswerving Deity is called the Silent One by the gods, and is said to consent (lit. sing together) with the Mind, and to be known by the Souls through Mind alone.[108] Elsewhere the Oracles demonstrate this Power which is prior to the highest Heaven as "Mystic Silence."[109] The Word, then, issuing from Silence is first a Monad, then a Duad, a Triad and a Hebdomad. For no sooner has differentiation commenced in it, and it passes from the state of Oneness ([Greek: monotaes]), than the Duadic and Triadic state immediately supervene, arising, so to say, simultaneously in the mind, for the mind cannot rest on Duality, but is forced by a law of its nature to rest only on the joint emanation of the Two. Thus the first natural resting point is the Trinity. The next is the Hebdomad or Septenary, according to the mathematical formula 2^{n}-1, the sum of _n_ things taken 1, 2, 3 ... _n_, at a time. The Trinity being manifested, _n_ here =3; and 2^{3}-1 = 7. Thus Simon has six Roots and the Seventh Power, seven in all, as the type of the Aeons in the Plerôma. These all proceed from the Fire. In like manner also the Cabeiric deities of Samothrace and Phoenicia were Fire-gods, born of the Fire. Nonnus tells us they were sons of the mysterious Hephaestus (Vulcan),[110] and Eusebius, in his quotations from Sanchuniathon, that they were _seven_ in number.[111] The Vedic Agni (Ignis) also, the God of Fire, is called "Seven-tongued" (Sapta-jihva) and "Seven-flamed" (Sapta-jvâla).[112] In the _Hibbert Lectures_ of 1887, Prof. A.H. Sayce gives the following Hymn of Ancient Babylonia to the Fire-god, from _The Cuneiform Inscriptions of Western Asia_ (iv. 15): 1. The (bed) of the earth they took for their border, but the god appeared not, 2. from the foundations of the earth he appeared not to make hostility; 3. (to) the heaven below they extended (their path), and to the heaven that is unseen they climbed afar. 4. In the Star(s) of Heaven was not their ministry; in Mazzaroth (the Zodiacal signs) was their office. 5. The Fire-god, the first-born supreme, into heaven they pursued and no father did he know. 6. O Fire-god, supreme on high, the first-born, the mighty, supreme enjoiner of the commands of Anu! 7. The Fire-god enthrones with himself the friend that he loves. 8. He reveals the enmity of those seven. 9. On the work he ponders in his dwelling-place. 10. O Fire-god, how were those seven begotten, how were they nurtured? 11. Those seven in the mountain of the sunset were born; 12. those seven in the mountain of the sunrise grew up. 13. In the hollows of the earth they have their dwelling; 14. on the high places of the earth their names are proclaimed. 15. As for them, in heaven and earth they have no dwelling, hidden is their name. 16. Among the sentient gods they are not known.
