Ephesus was founded as an Attic-Ionian colony in the 10th century BC on the Ayasuluk Hill, three kilometers (1.9 miles) from the center of ancient Ephesus (as attested by excavations at the Seljuk castle during the 1990s). The mythical founder of the city was a prince of Athens named Androklos, who had to leave his country after the death of his father, King Kadros. According to the legend, he founded Ephesus on the place where the oracle of Delphi became reality (“A fish and a boar will show you the way”). Androklos drove away most of the native Carian and Lelegian inhabitants of the city and united his people with the remainder. He was a successful warrior, and as a king he was able to join the twelve cities of Ionia together into the Ionian League. During his reign the city began to prosper. He died in a battle against the Carians when he came to the aid of Priene, another city of the Ionian League. Androklos and his dog are depicted on the Hadrian temple frieze, dating from the 2nd century. Later, Greek historians such as Pausanias, Strabo, the poet Kallinos, and the historian Herodotos reassigned the city’s mythological foundation to Ephos, queen of the Amazons.
The Greek goddess Artemis and the great Anatolian goddess Kybele were identified together as Artemis of Ephesus. The many-breasted “Lady of Ephesus”, identified with Artemis, was venerated in the Temple of Artemis, one of the Seven Wonders of the World and the largest building of the ancient world according to Pausanias (4.31.8). Pausanias mentions that the temple was built by Ephesus, son of the river god Caystrus before the arrival of the Ionians. Of this structure, scarcely a trace remains.
