ONE:His eyes rested for a moment on the upthrust wing of the submerged seaplane. His face changed expression. An idea flashed across his mind.Side by side, however, with these exalted aspirations, the old popular belief in a subterranean abode of souls survived under its very crudest forms; and here also modern explorations have brought to light very surprising evidence of the strength with which the grotesque idea of Charon the Stygian ferryman still kept its hold on the imagination of uneducated people. Originally peculiar to Greece, where it still exists under a slightly altered form, this superstition penetrated into the West at a comparatively early period. Thus in the tombs of Campania alone many hundred skeletons have been found with bronze coins in their mouths, placed there to pay their passage across the Styx; and explorations at Praeneste show that this custom reaches back to the middle of the237 fourth century B.C. We also learn from Lucian that, in his time, the old animistic beliefs were entertained to the extent of burning or burying the clothes, ornaments, and other appurtenances of deceased persons along with their bodies, under the idea that the owners required them for use in the other world; and it is to such deposits that our museums of classical antiquity owe the greater part of their contents.369
