Artemidorus Daldianus (Ancient Greek: Ἀρτεμίδωρος ὁ Δαλδιανός) or Ephesius was a professional diviner and dream interpreter who lived in the 2nd century AD.
[1] Artemidorus was surnamed Ephesius, from Ephesus, on the west coast of Asia Minor, but was also called Daldianus, from his mother's native city, Daldis in Lydia.
According to Artemidorus, the material for his work was gathered during lengthy travels through Greece, Italy and Asia, from diviners of high and low station.
According to the Suda,[2] Artemidorus also penned a Oiônoscopica (Οἰωνοσκοπικὰ) (Interpretation of Birds) and a Chiroscopica (Χειροσκοπικά) (Palmistry), but neither has survived, and the authorship is discounted.
The fragments of these authors, from Artemidorus and other sources, were collected by Del Corno in his Graecorum de re onirocritica scriptorum reliquiae (1969).
