Summary The article investigates the extent to which Greek necromancy fits into the wider eschatological, cultic and historical context of an epoch demarcated on the one hand by Homer and on the other by the Classical period. The oldest purported necromantic ritual, with the help of which Odysseus descended into the underworld, is a literary construct inspired especially by the heroic tomb-cults. Scenes depicting funereal necromancy, written by dramatists of the Classical period, were also drawn from this source. Ability, behavior and appearance of heroes were additionally ascribed to the so-called restless spirits and revenants and later came to include all the dead. The main cause of this was a change in eschatological ideas and especially heroization, which in the Roman period spread nominally to all the dead. Reports about necromancy include a high percentage of mythical and literarily-dramatized elements that simply do not correspond with contemporary ideas about the soul, the dead, the underworld and chthonic deities. It therefore appears almost certain that, at least to the end of the period described, necromancy was not carried out in reality but remained only the literary surmise of the possibility indicated by Homer.
