78 HERODOTUS. [CHAP. As Herodotus was an adherent of the Pythagorean School of . Philosophy, we cannot be surprised if we find him His General .... views of disagreeing with some of the geographical views of the Geography. ionj[an School. This point has already been noticed in speaking of Hecataeus, where we have seen that the historian derides the notion, which was still maintained by that school, that the Earth was a circular plane surrounded by the ocean stream l. Yet the cast of his own mind was essentially unphilosophical, and while he expresses incredulity about the opinions of his prede- „. „ . . cessors. he shews strange simplicity in his own His Pnmi- tive cosmicai conceptions of the order of nature.
