God as the one (Romanism gentile/pagan)

Before the things that really are, even the first principles of all things, is One Divine Being, prior even to the first God and King [Jupiter], abiding immovable in the aloneness of his own absolute unity. For neither is Intelligence nor any principle else intermingled with him, but he is established an exemplar of the God self-begotten, self-produced and only-begotten, the One truly Good. For he is the something Absolutely Great and Supreme, the Source of all things, and root of the first ideals subsisting in the Supreme Mind. Then from this One, the God [Jupiter] sufficient in himself caused himself to shine forth:3 and hence he is self-engendered and self-sufficient. For he is the Beginning and God of Gods, a unity proceeding from the One, subsisting before essence, and the principle of essence. For from him are being and essence; and he is called accordingly Noëtarch, Chief of the realm of thought.
