But, though Homer speaks of the _genius_ only as a ‘lesser god’ without further description, he implies clearly that the present custom of doing sacrifice to such a being for the foundation of any building was then in existence. Did the sacrifice ever involve human victims? A positive and certain answer cannot, I suppose, be made; but bearing in mind the many ancient traditions of human sacrifice in Greece and even the occasional continuance of the practice in the most civilised and enlightened age[713] I cannot doubt it. I suspect that, if we could obtain an earlier version of the story of Iphigenia than has come down to us, we should find that the wrath of Artemis had no part in it, but that human sacrifice was offered to the Winds or other _genii_ of the air--that the ‘maiden’s blood’ was, in the words of Aeschylus, ‘a sacrifice to stay the winds[714],’ ‘a charm to lull the Thracian blasts[715],’ that and nothing more. But a story still more strongly evidential of the custom is told by Pausanias[716]. In the war between Messenia and Sparta, when the Messenians had been reduced to extremities, ‘they decided to evacuate all their many towns in the open country and to establish themselves on Mount Ithome. Now there was there a town of no great size, which Homer, they say, includes in the Catalogue--“Ithome steep as a ladder.” In this town they established themselves, extending its ancient circuit so as to provide a stronghold large enough for all. And apart even from the fortifications the place was strong; for Ithome is as high as any mountain in the Peloponnese and, where the town lay, was particularly inaccessible. They determined also to send an envoy to Delphi,’ who brought them back the following oracle: A maiden pure unto the nether powers, Chosen by lot, of lineage Aepytid, Ye shall devote in sacrifice by night. But if ye fail thereof, take ye a maid E’en from a man of other race as victim, An he shall give her willingly to slay. And the story goes on to tell how in the end Aristodemus devoted his own daughter, and she became the accepted victim. Here Pausanias, it will be noticed, does not give any reason for the sacrifice being required. But three points in his narrative are highly suggestive. The story of the sacrifice follows immediately upon the mention of the building of new fortifications--and the foundation of what was to be practically a new city was eminently a question on which to consult the Delphic oracle; the powers to whom sacrifice is ordered are designated merely as νέρτεροι δαίμονες, the nearest equivalent in ancient Greek to _genii_; and the time of the sacrifice is to be night, when, according to modern belief, _genii_ are most active. If then modern superstition can ever teach us anything about ancient religion, it supplies the clue here. The maiden was to be sacrificed to the _genii_ of Mount Ithome to ensure the stability of the new fortifications.
