The Home of a God. Didyma was not a city but one of the three oracle places. It was a center of the cult of Apollo, the god of divination. Divination was always popular and Apollo Temple had been a very important place for the Paganist people until Christianity gave a fatal blow to paganism. Words are not enough to describe Apollo Temple because of its amazing dimensions. It measured 118 meters by 60 meters,which is slightly larger than a football field. There were 128 finely decorated columns, some of which are 19.50 meters high.
Didyma was the most renowned oracle of the Hellenic world, first mentioned among the Greeks in the Homeric Hymn to Apollo, but an establishment preceding literacy and even the Hellenic colonization of Ionia. Mythic genealogies of the origins of the Branchidae line of priests, designed to capture the origins of Didyma as a Hellenic tradition, date to the Hellenistic period. The ruins of Didyma are located at a short distance to the northwest of modern Didim in Aydin Province, Turkey,
Didyma was the largest and most significant sanctuary on the territory of the great classical city Miletus. To approach it, visitors would follow the Sacred Way to Didyma, about 17 km long. Along the way, were ritual waystations, and statues of members of the Branchidae family, male and female, as well as animal figures. Some of these statues, dating to the 6th century BC are now in the British Museum, taken by Charles Newton in the 19th century.
Greek and Roman authors laboured to refer the name Didyma to "twin" temples — not a feature of the site — or to temples of the twins, Apollo and Artemis, whose own cult center at Didyma was only recently established, or whether, as Wilamowitz suggested there is a connection to Cybele Dindymene, "Cybele of Mount Dindymon", is mooted. Recent excavations by the German team of archaeologists have uncovered a major sanctuary dedicated to Artemis, with the key ritual focus being water.
The 6th century Didymaion, dedicated to Apollo, enclosed its smaller predecessor, which archaeologists have identified. Its treasury was enriched by gifts from Croesus.
