Lumen de Lumine

It is a Tincture of the Saphiric Mine, and to define it substantially, it is the Aire of our little Invisible Fire-world. It produceth two noble effects, youth, and Hope: wheresoever it appears, it is an infallible sign of life, as you see in the spring-time, when all things are Green. The sight of it is cheerfull, and refreshing beyond all imagination. It comes out of the Heavenly Earth, for the Saphir doth spermatize, & injects her Tinctures into the Aether, where they are carried, and manifested to the Eye. This Saphir is equall of her self to the whole Compound, for she is threefold, or hath in her three severall essences. I have seen them all, not in Ayrie imaginarie suppositions, but really with my bodily eyes. And here we have Apollodorous his Mathematicall Problem resolved: namely that Pythagoras should sacrifice a hundred Oxen when hee found out, ὅτι τριγώνου ὀρθογωνίου ἡ ὀρθὴν γωνίαν ὑποτείνουσα ἴσον δύναται ταῖς περιεχούσαις, That the Subtendent of a right angl’d Triangle was equivalent to those parts which contain’d it, &c.
