Acheron

Acheron (Ach´eron). The current of the river Acheron, across which all souls had to pass to hear their decree from Pluto, was so swift that the boldest swimmer dare not attempt to breast it; and, since there was no bridge, the spirits were obliged to rely upon the aid of Charon, an aged boatman, who plied the only boat that was available. He would allow no soul to enter this leaky craft until he had received the obolus, or fare, which the ancients carefully placed under the tongue of the dead, that they might not be delayed in their passage to Pluto. Those who had not their fare were forced to wait one hundred years, when Charon reluctantly ferried them over without charge.
