Hellenistic naiskos of Apollo. Therefore, it seemed likely they belonged to the elusive and tantalising temple of Artemis because of the twinning stylistic components. But this idea could not be proved until 2012. The architrave and frieze blocks from the Artemis temple are deeper and wider than the ones from Apollo's naiskos. A cornice block (consisting of geison and sima), already found in 1909, but first investigated in 2012 belongs to them. It was the keystone to solve the riddle. For architrave, frieze and cornice are derived from a wider temple than the naiskos. Further they match perfectly to the construction drawing in the sekos. Finally this construction drawing matches the proportions of the new temple foundation. That means the Ionic temple of Artemis had four front columns and its length was exactly three times longer than its width. Another difference between the naiskos of Apollo and the temple of his sister Artemis concerns the time of their construction. The ornamentation of the naiskos can stylistically be dated around 300 BC, but the ornaments of the temple of Artemis date in the 2nd century BC. Hence the date of the new temple is known, but though it seems likely that it was dedicated to Artemis there remains speculation, especially as no inscription was found on the architectural members? Older inscriptions from the 6th century BC show that beside Apollo, both Artemis and Hekate had been worshipped in Didyma. Another inscription from the 3rd century BC mentions the cult statue of Artemis. In later inscriptions reconstruction works of the temple of Artemis are reported. Therefore, there can be no doubt that Artemis had her own temple in Didyma. She was the main deity beside Apollo, and to no other deity worshipped in Didyma is a temple documented. Furthermore, Artemis is the twin sister of Apollo. All this leads to the conclusion that this temple designed according to Apollo's naiskos must be the one of Artemis and it stood originally on the promontory north of the temple of Apollo. In the end these results contradict Klaus Tuchelt's view that the sanctuary of Artemis was situated west of the sacred way, as Helga Bumke had some years ago already suggested. Sacred Way with the Roman baths The Sacred Way inside the sanctuary of Apollo was excavated under Klaus Tuchelt. He found the remains of different buildings from the Archaic period along the wide
