Both the Christian and the Mahomedan religions have begun during the historical age, have been propagated from one common centre, and have been erected upon the ruins of a different pre-existing faith. With none of these particulars did Grecian Paganism correspond. It took rise in an age of imagination and feeling simply, without the restraints, as well as without the aid, of writing or records, of history or philosophy: it was, as a general rule, the spontaneous product of many separate tribes and localities, imitation and propagation operating as subordinate causes; it was moreover a primordial faith, as far as our means of information enable us to discover. These considerations explain to us two facts in the history of the early Pagan mind: first, the divine mythes, the matter of their religion, constituted also the matter of their earliest history; next, these mythes harmonized with each other only in their general types, but differed incurably in respect of particular incidents. The poet who sung a new adventure of Apollo, the trace of which he might have heard in some remote locality, would take care that it should be agreeable to the general conceptions which his hearers entertained respecting the god. He would not ascribe the cestus or amorous influences to Athênê, nor armed interference and the ægis to Aphroditê; but, provided he maintained this general keeping, he might indulge his fancy without restraint in the particular events of the story.[115] The feelings and faith of his hearers went along with him, and there were no critical scruples to hold them back: to scrutinize the alleged proceedings of the gods was repulsive, and to disbelieve them impious. And thus these divine mythes, though they had their root simply in religious feelings, and though they presented great discrepancies of fact, served nevertheless as primitive matter of history to an early Greek: they were the only narratives, at once publicly accredited and interesting, which he possessed. To them were aggregated the heroic mythes (to which we shall proceed presently),—indeed the two are inseparably blended, gods, heroes and men almost always appearing in the same picture,—analogous both in their structure and their genesis, and differing chiefly in the circumstance that they sprang from the type of a hero instead of from that of a god. [115] The birth of Apollo and Artemis from Zeus and Lêtô is among the oldest and most generally admitted facts in the Grecian divine legends. Yet Æschylus did not scruple to describe Artemis publicly as daughter of Dêmêtêr (Herodot. ii. 156; Pausan. viii. 37, 3). Herodotus thinks that he copied this innovation from the Egyptians, who affirmed that Apollo and Artemis were the sons of Dionysos and Isis.
