The search for knowledge of the future and for divine help is found in all ancient Mediterranean cultures. The key question of this e-book is: What are the interdependences between divination and processes of individualization or de-individualization in the ancient world? Individualization is understood as a process of change on the societal level. In contrast, individuation is a development on the personal level. Discussions about the definition of these terms are continuing. Divination may always have some effects on processes of individuation and individualization. Divination may be a means – and this list does not claim to be exhaustive – of legitimising decisions, to decide competition or to achieve distinctiveness. This e-book covers aspects from archaic Greece to the High Empire. Not all articles argue along the same lines: nothing highlights better the lively debate and the many open questions in the field of ancient divination.
