Chapter vii.
Of the Number of Four, and the Scale thereof.
The Pythagorians call the Number of four Tetractis, and prefer it before all the vertues of Numbers, because it is the foundation, and root of all other numbers; whence also all foundations, as well in artificiall things, as naturall, and divine, are four square, as we shall shew afterwards: and it signifies solidity, which also is demonstrated by a four square figure. For the number four is the first four square plain, which consists of two proportions, whereof the first is of one to two, the latter of two to four, and it proceeds by a double procession and proportion, viz. of one to one, and of two to two, beginning at a unity, and ending at a quaternity: which proportions differ in this, that according to Arithmatick, they are unequall to one the other: but according to Geometry are equall. Therefore a four square is ascribed to God the Father, and also contains the mysterie of the whole Trinity: for by its single proportion, viz. by the first of one to one, the unity of the paternall substance is signified, from which proceeds one Son, equall to him; by the next procession, also simple, viz. of two to two, is signified by the second procession the Holy Ghost from both, that the Son be equall to the Father by the first procession; and the Holy Ghost be equall to both by the second procession. Hence that superexcellent, and great name of the divine Trinity of God is written with four letters, viz. Yod, He, and Vau; He, where it is the aspiration He, signifies the proceeding of the spirit from both: for He being duplicated, terminates both syllables, and the whole name, but is pronounced Jova, as some will, whence that Jovis of the heathen, which the Ancients did picture with four ears, whence the number four is the fountain, and head of the whole divinity. And the Pythagorians call it the perpetuall fountain of nature: for there are four degrees in the Scale of nature, viz. to be, to live, to be sensible, to understand.
