Abae was an ancient town in the northeastern corner of ancient Phocis, in Greece, near the frontiers of the Opuntian Locrians, said to have been built by the Argive Abas, son of Lynceus and Hypermnestra, and grandson of Danaus. This bit of legend suggests an origin or at least an existence in the Bronze Age. Its protohistory supports a continued existence in Iron-Age antiquity. It was famous for its oracle of Apollo Abaeus, one of those consulted by Croesus, king of Lydia, and Mardonius, among others. The site of the oracle was rediscovered at Kalapodi and excavated in modern times. The results confirm an archaeological existence dating from the Bronze Age, as is suggested by the lore.

An oracle is a person or thing considered to provide insight, wise counsel or prophetic predictions, most notably including precognition of the future, inspired by deities. If done through occultic means, it is a form of divination.
