From the imaginations of Gothic short-story writers such as Edgar Allen Poe, Nathaniel Hawthorne, Mary Shelley, and later weirdists such as H.P. Lovecraft came one of the most complex of villains--the mad scientist. Promethean Horrors presents some of the greatest mad scientists ever created, as each cautionary tale explores the consequences of pushing nature too far. These savants take many forms: there are malcontents who strive to create poisonous humans; technologists obsessed with genetic splicing; mesmerists interested in the way consciousness operates after death, and inventors who believe in a hidden reality. United by an unhealthy obsession with wanting to reach beyond their circumstances, these mad scientists are marked by their magical capacity to alter the present, a gift that always comes at a price.
