Chapter I.—Thales; His Physics and Theology; Founder of Greek Astronomy. It is said that Thales of Miletus, one of the seven 40 wise men, first attempted to frame a system of natural philosophy. This person said that some such thing as water is the generative principle of the universe, and its end;—for that out of this, solidified and again dissolved, all things consist, and that all things are supported on it; from which also arise both earthquakes and changes of the winds and atmospheric movements, 41 and that all things are both produced 42 and are in a state of flux corresponding with the nature of the primary author of generation;—and that the Deity 43 is that which has neither beginning nor end. This person, having been occupied with an hypothesis and investigation concerning the stars, became the earliest author to the Greeks of this kind of learning. And he, looking towards heaven, alleging that he was carefully examining supernal objects, fell into a well; and a certain maid, by name Thratta, remarked of him derisively, that while intent on beholding things in heaven, he did not know 44 what was at his feet. And he lived about the time of Crœsus. 40     [These were: Periander of Corinth, b.c. 585; Pittacus of Mitylene, b.c. 570; Thales of Miletus, b.c. 548: Solon of Athens, b.c. 540; Chilo of Sparta, b.c. 597; Bias of Priene; Cleobulus of Lindus, b.c. 564.] 41     Or, “motions of the stars” (Roeper). 42     Or, “carried along” (Roeper). 43     Or,“ that which is divine.” See Clemens Alexandrinus, Strom ., v. pp. 461, 463 (Heinsius and Sylburgius’ ed.). Thales, on being asked, “What is God?” “That,” replied he, “which has neither beginning nor end.” 44     Or, “see.”
