The healing oracles were based on the chthonic provenance of dreams. This article refers to the Asdepeiqn at Epidaurus, and describes the ritual of sleeping in this sanctuary. Furthermore, it presents the two stone slabs, which, under the general title “Healings performed by Apollo and Asclepius”, record forty-three incidents of healing through dreams, that can be assigned to the second half of the fourth century B.C. Finally, an attempt is made to analyse the Epidaurian healing dreams, which are compared to the dreams of the Hippocratic School and to those of the Artemidoros’ oneirocritic manual.
