Apollo. From the Hadrianic nymphaeum, on the lower agora. This was situated close to the Apollo Klarios temple, so named after the Klarios oracle in Ephesus.

In the middle imperial times the city’s first monumental fountains of Roman type were constructed on the slopes to the north of the Lower Agora. Instead of the Greek style of fountain house where the water was protected from pollution and heat by being concealed in a portico, the Roman nymphaea used the water as an architectural feature. Water filled open basins and reflected the rich façade with aediculae (columnar cubicles) alternating with niches in the back wall. Similar facades were built in the western provinces of Anatolia from the latter half of the 1st century AD onwards. However, they also very soon made their way to Sagalassos. The oldest one, with nine niches in its back wall, was erected along the northern edge of the Lower Agora around AD 100. The fact that it was only one storey high instead of two like the Western Anatolian prototypes may be a feature of Southern Anatolia. One generation later, in middle Hadrianic times (circa 130-138 AD), a second nymphaeum, this time two storeys high, was built on a terrace immediately above and behind the first one. Its rich architecture hid the plain façade of the Odeion (concert hall) behind. In Severan times, possibly under Caracalla (first decades of the 3rd century AD) a third nymphaeum, largely repeating the aspect of the first one, was built a meter in front of the latter. At the time of the destruction around the middle of the 7th century AD, its niches still contained some of their (largely re-used) sculptures: a Hera Ephesia, a Tyche and two winged Victories.
