It is worth remarking, that many of the punishments described in the various accounts of hell are punishments of pressure and constriction. Dante’s sinners are buried in mud, shut up in the trunks of trees, frozen solid in blocks of ice, crushed beneath stones. The Inferno is psychologically true. Many of its pains are experienced by schizophrenics, and by those who have taken mescalin or lysergic acid under unfavorable conditions.*
