The find was made almost exactly one year after we discovered the remains of a colossal (ca. 5 m; 16 foot) statue of the emperor Hadrian (A.D. 117-138) at a spot about 6 m (20 feet) away. The Hadrian statue—represented by a head and the lower part of the right leg and joining foot—is currently on display in the rotunda of the British Museum where it is the centerpiece of the exhibition Hadrian: Empire and Conflict.
Both the Hadrian statute and Faustina head come from the largest room of the Roman Baths at Sagalassos, which have under excavation for the past 12 years. This room—cross-shaped, with mosaic floors, and up to 1250 sq. meters—was most likely a cold room or frigidarium. Other colossal statues once occupied this room, as shown by the front part of two female feet of colossal dimensions we discovered last summer standing on the floor and surrounded by mosaics which still follow the contours of the female statue's long dress.
It's a report from the field by the director. Good read.
