The Cult
No city worshipped Óneiros with a temple, but Greeks did cult-address their dreams, and the practice is well documented. The great instrument was incubation: the sick purified themselves, sacrificed, and lay down to sleep in the dormitory (enkoimeterion) of a healing sanctuary — Epidaurus above all, then Pergamon, Cos, and Lebena — expecting the god Asklepios to appear in sleep and prescribe. The iamata, the votive stelae of Epidaurus, record hundreds of such dreams together with their cures. Dreams also received direct invocation: the Orphic Hymns close with a prayer 'To the Dreams' (hymn 86), and professional interpreters — Artemidorus of Daldis is the survivor — mapped the whole commerce between sleeper and divine. What was worshipped was not the dream as person but the dream as message: a night-letter whose reading was itself a craft.
