Pre-Christian hells were highly unpleasant too, and called upon the same sadistic ingenuity for their invention. However, some of the early ones we know of—most notably the Hindu—were limited in time. A sinner, for example, might be sentenced to a given number of years in hell, where every day counted as 6,400 human years. If he slew a priest, the sentence thus adjusted would be 149,504,000,000 years. At this point, he was allowed nirvana, which seems to mean annihilation. It was left to Christians to find a hell from which there was no possible appeal.
