Such eastern Greek influences on thinking in the mainland imply a general Ionian intellectual primacy, which is most obvious in the sphere of speculative thinking. One 6th-century city above all, Miletus in Anatolia, produced a formidable cluster of thinkers (it is best to avoid the metaphor of a series, with its implication that intellectual progress was linear or organized). The cosmological theories of Thales, Anaximander, and Anaximenes are remarkable more for their method—a readiness to work with abstractions, such as water, or the unlimited, to which they accorded explanatory power—than for the actual solutions they reached. It is an interesting modern suggestion that all three were influenced by Persian or even ultimately Indian thought. The suggestion is especially plausible for Heraclitus (fl. 500 bce), because his native city of Ephesus, with its cult of Artemis (a goddess whose worship has features borrowed from that of her native counterpart Anahita) and its large Persian population, was always—down to and including Roman times—especially open to Iranian influences.
That raises the general question of intellectual awareness of the Persian empire, which conquered the Lydian kingdom of Croesus about 546 bce and so inherited Lydian rule over the Greeks of the Asiatic coastal mainland. The poetry of another poet-philosopher, Xenophanes, from the Ionian city of Colophon, addressed itself to problems of religion and concluded that if horses had gods those gods would be horses, just as Ethiopian gods are black-skinned and Thracian gods have blue eyes. Xenophanes’ awareness of the differences between cultures could plausibly be linked to the turnover of empires around him, even if there were no confirmation in the form of a poem describing a symposium at which men “sit drinking sweet wine and chewing chick-pea, and asking each other ‘How old were you when the Mede came?’ ” (The Medes were the predecessors of the Persians, and the Greeks sometimes, as here, conflated the two.) In his “sympotic” aspect—that is, his emphasis on the symposium—Xenophanes was a child of his age; he was more unusual in his rejection, in another poem, of athletic values because of what he thought to be their coarsening effects.
One way in which Persia influenced Greek thought was via individual refugees and refugee communities. Thus, Pherecydes of Syros has been seen as a theologian who emigrated from Anatolia to the west after Cyrus’s arrival. (Whether there was a more general westward diaspora of Magi, members of the Persian religious caste, is disputable.) Whole communities left Anatolia under duress; some of them became famous in later philosophical history, such as Phocaea, which founded Elea in Italy, a place famous for philosophy, and Teos, which founded Abdera in northern Greece, the home of the 5th-century atomists Democritus and Leucippus. Finally, one must allow for a considerable Egyptian and western Semitic influence on Archaic Greek religion, political organization, and thought, though its precise extent and the means by which it was mediated await proper scientific treatment.
The greatest literary stimulus provided by neighbouring cultures like the Persian was in the field of ethnography and history. The “inquiries” (historiai) of Herodotus, from Asiatic Halicarnassus, will be discussed later, but they would not have been possible without the writings of Hecataeus, another Milesian (c. 500 bce), who treated both geography and myth in works that survive today only in fragmentary form. Hecataeus was a “logographer,” a prose writer as opposed to the poets so far considered. The gradual move from verse to prose as an intellectual medium goes together with a shift from oral to written culture; but that second shift was not complete even in Athens until well into the 5th century, and there is a case for thinking that even then and in the “document-minded” 4th century “oral” and “written” attitudes coexisted.
Inquiries of Hecataeus’s kind had a certain practical application: knowledge of the world, in the most literal sense of that phrase, was of obvious usefulness in a city like Miletus with its colonial connections (in the Black Sea region) and its long-distance trade. (A close connection with Sybaris in southern Italy is implied by Herodotus’s story that, when Sybaris was destroyed in 510 bce, the Milesians collectively went into mourning; and Herodotus says that at the beginning of the Ionian revolt, in 500–499, Miletus was at the height of its prosperity.) When the time came to confront Persia politically, after 500, Hecataeus had the standing to suggest initiatives for shared Ionian defense. Surely this standing was conferred as much by what Hecataeus knew as by who he was. On the longer perspective, it was awareness of Persia that helped the Greeks, as it helped the Jews about the same time, to define themselves by opposition. The existence of a great and menacing culture perceived as importantly different was thus a factor in the formation of a common late Archaic Greek culture.
These political and ideological consequences of Archaic Greek thought can be seen as a kind of practical application of theory. The greatest applied scientific achievements of the Archaic period, however, were in the sphere of military technology—the trireme and the hoplite. Some Asian influence can, it is true, be posited for each (Phoenician for the trireme, Assyrian for hoplite armour); but their refinement and effective use was Greek. The victories of the Persian Wars were won as much by the anonymous Archaic developers of the trireme and the hoplite as by the particular Greeks of 490 and 480–479. Classical Greek civilization The Persian Wars
Between 500 and 386 bc Persia was for the policy-making classes in the largest Greek states a constant preoccupation. (It is not known, however, how far down the social scale this preoccupation extended in reality.) Persia was never less than a subject for artistic and oratorical reference, and sometimes it actually determined foreign policy decisions.
The situation for the far more numerous smaller states of mainland Greece was different inasmuch as a distinctive policy of their own toward Persia or anybody else was hardly an option for most of the time. However, Eretria, by now a third-class power, had its own unsuccessful “war” with Persia in 490, and some very small cities and islands were proud to record on the “Serpent Column” (the victory dedication to Apollo at Delphi) their participation on the Greek side in the great war of 480–479. But, even at this exalted moment, choice of sides, Greek or Persian, could be seen, as it was by Herodotus, as having been determined either by preference for local masters or by a desire to spite an equal and rival state next door. (He says this explicitly about Thessaly, which “Medized”—i.e., sided with the Persians—and its neighbour and enemy Phocis, which did not.) Nor is it obvious that for small Greek places the change to control by distant Persia would have made much day-to-day difference, judging from the experience of their kinsmen and counterparts in Anatolia or of the Jews (the other articulate Persian subject nation). Modern Western notions of religious tolerance do not apply, however.
It remains true that Persia had no policy of dismantling the social structures of its subject communities or of driving their religions underground (though it has been held that the Persian king Xerxes tried to impose orthodoxy in a way that compelled some Magi to emigrate). Persia certainly had no motive for destroying the economies of the peoples in its empire. Naturally, it expected the ruling groups or individuals to guarantee payment of tribute and generally deferential behaviour, but then the Athenian and Spartan empires expected the same of their dependents. The Athenians, at least, were strikingly realistic and undogmatic about not demanding regimes that resembled their own democracy in more than the name. The Ionian revolt
But the experience of the Asiatic Greek cities was different again, because it was precisely here that the great confrontation between Greeks and Persians began, about 500 bc. The first phase of that confrontation was the “Ionian revolt” of the Asiatic Greeks against Persia (despite the word Ionian, other Asiatic Greeks joined in, from the Dorian cities to the south and from the so-called Aeolian cities to the north, and the Carians, not Greeks in the full sense at all, fought among the bravest). The puzzle is to explain why the revolt happened when it did, after nearly half a century of rule by the Achaemenid Persian kings (that is, since 546 when Cyrus the Great conquered them; his main successors were Cambyses [530–522], Darius I [522–486], Xerxes I [486–465], Artaxerxes I [465–424], and Darius II [423–404]). Too little is known about the details of Persian rule in Anatolia during the period 546–500 to say definitely that it was not oppressive, but, as stated above, Miletus, the centre of the revolt, was flourishing in 500.
