Oneirocritica (The Interpretation of Dreams) is an ancient Greek treatise on dream interpretation written by Artemidorus in the 2nd century AD, and is the first extant Greek work on the subject, in five books. The first three volumes were intended for the general public, providing an encyclopedic treatment of the subject matter of dreams, and the remaining two volumes were written for the private use of the author's son, a novice dream interpreter. Artemidorus inscribed the book "Artemidorus of Daldis", despite having been born in Ephesus, to commemorate the little-known birthplace of his mother in Lydia.
Artemidorus suggests that dreams are unique to the individual, and that a person's waking life will affect the symbols in his dreams. He shows awareness of the dreaming mind's capacity to use metaphors in its messages.
Artemidorus' Oneirocritica is the point of reference of Michel Foucault's The History of Sexuality, Vol. 3: The Care of the Self, which analyzes the text as a practical, experiential guide rather than a moral reflection or evaluation. It reveals culturally salient patterns relating to "the ethical experience of the aphrodisia."
