Asia Minor Sigillata group B (Zahn 1904, 40-47): R. Zahn stated in 1904 that his Asia Minor Sigillata group B was produced in Pergamon (Zahn 1904, 40-47). The clay body was described as non-micaceous buff clay covered by a red and glossy slip. The vessels comprised Arretina forms and forms influenced by the local Hellenistic production, with production beginning in the 2nd century BCE. However, due to the description of the fabric, this was probably not Sigillata produced in Pergamon.
Knipowitsch group C ((Knipowitsch 1929, 21-29): T. Knipowitsch classified the Pergamenian Sigillata as her group C (Knipowitsch 1929, 21-29) with brownish red-slipped vessels of Augustan date produced in Pergamon and Pitane. In her group the slip was of lesser quality than the Arretina one. This group was not equated with Zahn’s Asia Minor Sigillata group B because of differences in shape and fabric.
Pergamene Ware (Waagé 1948, 18-28, 32-38): F. O. Waagé used the term Pergamene Ware to describe vessels with a red slip (Waagé 1948, 18-28. 32-38). He divided the ware into Hellenistic Pergamene Ware and early Roman Pergamene Ware to distinguish the diverse sets of forms.
Eastern Sigillata C (Kenyon 1957, 281-288): This term was introduced by K. Kenyon in 1957 (Kenyon 1957, 281-288). She used it for the type of pottery found in Pitane (based on the publication of Loeschke 1912, 344-407), but stated that there might have been other production places, but without mentioning Pergamon. Eastern Sigillata C came to be one of the most frequently used terms for this ware type, although sometimes with a slightly differing characterization of style or production place. For example, P. Hellström used Eastern Sigillata C for the Sigillata production of Pitane and Pergamon (Hellström 1965, 29-30).
Lokal-pergamenische Ware (Schäfer 1962, 777-802): J. Schäfer classified the Sigillata of Pergamon with a new name to emphasize its local production (Schäfer 1962, 777-802). He described vessel’s slip as orangish red to reddish brown, more or less shiny and often irregular. The vessel forms are more numerous as he included Hellenistic forms with a kind of pre-red slip. Therefore, chronologically the Lokal-pergamenische Ware ranges from the 2nd century BCE to the 1st century CE.
Echt-pergamenische Ware (Ziegenaus – de Luca 168, 155): G. de Luca used this name for vessels with red slip definitely manufactured in Pergamon (Ziegenaus – de Luca 168, 155). The ceramic she included in this group can be dated between the late 1st century BCE and the late 1st century CE, so several Hellenistic forms are not extant, and the repertoire is mostly influenced by Italian models.
Pergamenische Sigillata (Meyer-Schlichtmann 1988): C. Meyer-Schlichtmann introduced a new term which is now – aside Eastern Sigillata C – common (Meyer-Schlichtmann 1988). As his classification was meant to be a kind of continuation of Kenyon’s system, Pergamenische Sigillata should have been used on an equal level to the other Eastern Sigillata groups, but with the distinct knowledge of the production place. So he consciously separated the Pergamenian and Pitane production. The slip colour of Meyer-Schlichtmann’s Pergamenische Sigillata had a wider variety than previously; he incorporated black, brown, reddish brown and red as well as bi-coloured vessels. For the first time the red colour was not the dominant or sole characteristic of this ware type. For him Pergamenische Sigillata started in the second half of the 2nd century BCE and was in the mid-2nd century CE removed by the late Roman Rotfirniskeramik. Hence, apart from Italian-influenced vessels typical Hellenistic forms and local inventions are now labelled as Sigillata.
Red-gloss wares of the Pergamon region (Hayes 2008, 49-52): This term was used by J. W. Hayes to again describe vessels with a red slip (Hayes 2008, 49-52). He distinguished two groups. The first group was produced in Pergamon and Pitane in the 1st centuries BCE/CE, the second one only in Pitane commencing in the late 1st century CE and lasting until the second half of the 3rd century CE. The first group includes forms of Hellenistic origin as well as the Pergamenian inventions, while the second group displays forms known as the early Late Roman C ware.
