This workshop was uncovered during rescue excavations between 1977 and 1980 in the valley of the river Ketios at the eastern slope of the city hill of Pergamon. Four workshop complexes with eleven ovens and five additional ovens were excavated (Poblome et al. 2001; Bounegru 2014), although the dimensions of the potters’ quarter were most likely much larger. During the excavations it was conspicuous that in one complex the largest number of moulds for Hellenistic relief bowls was found, while in another one moulds for appliqué ware came to light (Bounegru 2014, 84). In the other two workshops the production of Sigillata with stamps prevailed. Presumably the single workshops concentrated on a specific type of pottery, although archaeometric analyses proves probably not exclusively so. One specific chemical group comprised different forms of Hellenistic and Roman slipped and un-slipped, decorated and un-decorated vessels (Japp 2009; Mommsen – Japp 2009; Schneider – Japp, 2009). Currently only selected Table Ware has been published from the contexts, but the material found there speak in favour of an additional production of some specific types of Coarse Ware. The excavator S. Erdemgil dated the production in the preliminary reports between the 3rd/2nd centuries BCE and the 4th century CE, while one workshop situated in an anabranch of the Ketios was active until the 6th century CE (Erdemgil 1980, 103-107). According to the researcher in charge of the publication two production phases have to be distinguished as the area was used in between as necropolis (Bounegru 2003, 137-140; Bounegru 2014). One lasted from the mid-3rd century until the end of the 1st century BCE, while the second phase commenced in the 4th century and ceased in the second half of the 6th century CE. This interpretation has to be doubted as within the material found in this potters’ quarter and analysed by WD-XRF forms of the 1st and 2nd century CE have been observed (Japp 2009, 200; 214 Perga 15; 217 Perga 28; 218 Perga 30. 32). Moreover, a selected study of diagnostic fragments placed production between the mid-2nd century BCE and the mid-2nd century CE (Poblome et al. 2001). Perhaps the site underwent changes during its existence when parts of it were overbuilt with tombs. However, in other areas the production was obviously not completely stopped.
