... (And they (_i. e._ the Chaldæans) declare there are “terms”[2] of the stars in each zodiacal sign extending from one given part)[3] to [another given part in which some particular star has most power. About which there is no mere chance difference] among them [as appears from their tables]. But they say that the stars are guarded[4] [when they are midway between two other stars] in zodiacal succession. For instance, if [a certain star should occupy the first part] of a zodiacal sign and another [the last parts, and a third those of the middle, the one in the middle is said to be guarded] by those occupying the parts at the extremities. [And they say that the stars behold one another and are in accord with one another] when they appear triangularly or quadrangularly. Now those form a triangular [Sidenote: p. 54.] figure[5] and behold one another which have an interval of three zodiacal signs between them and a square those which have one of two signs.... ([6]Such then seems to be the character of the Chaldæan method. And in that which has been handed down it remains easy to understand and follow the contradictions noted. And some indeed try to teach a rougher way as if earthly things have no sympathy[7] at all with the heavenly ones. For thus they say, that the ambient[8] is not united as is the human body, so that according to the condition) of the head the lower parts [suffer with it and the head with the lower] parts, and earthly things should suffer along with those above the moon. But there is a certain difference and want of sympathy between them as they have not one and [the] same unity.
