6. But since also they make a theory about the influence of the zodiacal signs to which they say the things brought forth are likened, we shall not omit this. For example, they say that he who is born under Leo will be courageous,[38] and he who is born under Virgo straight-haired, pale-complexioned, [Sidenote: p. 65.] childless and bashful. But these things and those like them deserve laughter rather than serious consideration.[39] For according to them an Ethiopian can be born under Virgo, and if so they allow he will be white, straight-haired and the rest. But I imagine that the ancients gave the names of the lower animals to the stars rather because of arbitrariness[40] than from natural likeness of shape. For what likeness to a bear have the seven stars which stand separate from one another? Or to the head of a dragon those five of which Aratus says:--
Two hold the temples, two the eyes, and one beneath Marks the chin point of the monster dread.-- (Aratus, _Phainomena_, vv. 56, 57.)
7. That these things are not worthy of so much labour is thus proved to the right-thinkers aforesaid, and to those who give no heed to the inflated talk of the Chaldæans, who with assurance of indemnity make kings to disappear [Sidenote: p. 66.] and incite private persons to dare great deeds.[41] But if he who has given way to evil fails, he who has been deceived does not become a teacher to all whose minds the Chaldæans wish to lead endlessly astray by their failures. For they constrain the minds of their pupils when they say that the same configuration of the stars cannot occur otherwise than by the return of the Great Year in 7777 years.[42] How then can human observation agree[43] in so many ages upon one geniture? And this not once but many times, since the destruction of the cosmos as some say will interrupt the observation, or its gradual transformation will cause to disappear entirely the continuity of historical tradition.[44]] The Chaldaic art must be refuted by more arguments, although we have been recalling it to memory on account of other matters and not for its own sake. But since we have before said that we will omit none of the opinions current among the Gentiles,[45] by reason of the many-voiced craft of the heresies, let us see what they say also who have [Sidenote: p. 67.] dared to speculate about magnitudes. Who, recognizing the variety of the work of most of them, when another has been utterly deceived in a different manner and has been yet held in high esteem, have dared to say something yet more grandiose than he, so that they may be yet more glorified by those who have already glorified their petty frauds. These men postulate circles and triangular and square measures doubly and triply.[46] There is much theory about this, but it is not necessary for what lies before us.
