The four great inscriptions from the late 4th century B.C. found at Epidauros (IG 42,1, Nr. 121-124) are analysed. They contain 70 preserved iamata (healing reports) published on stelai erected for public inspection and constructive reading. They narrate healing events that took place at the sanctuary of Asklepios. The first stele begins with the title “Healings by Apollon and Asklepios,” but Apollo is named only here, never in the iamata themselves. Moreover, the reports do not only include healings, but also punishment miracles and mantic oracles; the god also puts a broken vessel back together and locates missing treasure. The individual reports often begin by giving the name and place of residence of the person concerned, but sometimes they remain anonymous. The sources of the reports and the question of their authors is dealt with, as well as the places of residence of the visitors who came from everywhere throughout the Greek world, not only from the Greek mainland, but also from Asia Minor, one as far as from Herakleia in Pontos. Special attention is given to the question what ultimately happened in the Abaton. A few parallels, including some from modern times, are considered, as in the case of the Asklepieion of Cos, where no similar healing activity is testified.
