Those conditions first arose in the Ionian cities; because there first did Greek citizens attain commercial wealth, [467] as a result of adopting the older commercial civilization whose independent cities they conquered, and of the greater rapidity of development which belongs to colonies in general. [468] There it was that, in matters of religion and philosophy, the comparison of their own cults with those of their foreign neighbours first provoked their critical reflection, as the age of primitive warfare passed away. And there it was, accordingly, that on a basis of primitive Babylonian science there originated with Thales of Miletos (fl. 586 B.C.), a Phoenician by descent, [469] the higher science and philosophy of the Greek-speaking race. [470] It is historically certain that Lydia had an ancient and close historical connection with Babylonian and Assyrian civilization, whether through the "Hittites" or otherwise (Sayce, Anc. Emp. of the East, 1884, pp. 217-19; Curtius, Griech. Gesch. i, 63, 207; Meyer, Gesch. des Alterth. i, 166, 277, 299, 305-10; Soury, Bréviaire de l'hist. du matérialisme, 1881, pp. 30, 37 sq. Cp. as to Armenia, Edwards, The Witness of Assyria, 1893, p. 144); and in the seventh century the commercial connection between Lydia and Ionia, long close, was presumably friendly up to the time of the first attacks of the Lydian Kings, and even afterwards (Herodotos i, 20-23), Alyattes having made a treaty of peace with Miletos, which thereafter had peace during his long reign. This brings us to the time of Thales (640-548 B.C.). At the same time, the Ionian settlers of Miletos had from the first a close connection with the Karians (Herod. i, 146, and above pp. 120-21), whose near affinity with the Semites, at least in religion, is seen in their practice of cutting their foreheads at festivals (id. ii, 61; cp. Grote, ed. 1888, i, 27, note; E. Curtius, i, 36, 42; Busolt, i, 33; and Spiegel, Eranische Alterthumskunde, i, 228). Thales was thus in the direct sphere of Babylonian culture before the conquest of Cyrus; and his Milesian pupils or successors, Anaximandros and Anaximenes, stand for the same influences. Herakleitos in turn was of Ephesus, an Ionian city in the same culture-sphere; Anaxagoras was of Klazomenai, another Ionian city, as had been Hermotimos, of the same philosophic school; the Eleatic school, founded by Xenophanes and carried on by Parmenides and the elder Zeno, come from the same matrix, Elea having been founded by exiles from Ionian Phokaia on its conquest by the Persians; and Pythagoras, in turn, was of the Ionian city of Samos, in the same sixth century. Finally, Protagoras and Demokritos were of Abdera, an Ionian colony in Thrace; Leukippos, the teacher of Demokritos, was either an Abderite, a Milesian, or an Elean; and Archelaos,
