Among the noble families from Beroia in Macedonia under the Antigonids epigraphic sources attest a family whose representatives bore the names Hippostratos and Kallippos (EKM I. 1, 4–5, 18; 4, 11–12). From Diodorus we know about a certain Kallippa, former concubine (pallakis) of King Perseus; later she lived with Athenaios, an Attalid prince (Diod. 32. 15. 4–5), the youngest brother of kings Eumenes II and Attalos II. It is not known when Kallippa had a relationship with Perseus. It could have been before the marriage of the last Antigonid to the Seleucid princess Laodike (ca 178–177 BC.), during this marriage, or both. Being one of the commanders of the contingent from Pergamon, Athenaios participated in the Third Macedonian War including the battle of Pydna (Liv. 42. 55. 7–8; 42. 56. 5; SEG XXV. 118 = = ISE I. 35, 13–16). The Attalid prince also accompanied Aemilius Paullus on his journey across Greece in 168 or 167 BC. (Liv. 44. 27. 6). The relationship between Athenaios and Kallippa could have begun at this time, shortly after Perseus’ surrender and the fall of the Antigonid monarchy. According to Diodorus, ca 150–149 BC. a certain Macedonian by name of Nikolaos, a friend of Andriskos, who claimed the Macedonian throne, arranged (obviously on the territory of the Attalid Kingdom) for him a meeting with Kallippa. She gave Andriskos the king’s robe and the diadem, a sum of money as well as two slaves (Diod. 32. 15. 4–5). It is quite plausible that Kallippa, who bore an aristocratic name rare for Macedonia (not attested in LGPN IV) and was during her life connected with representatives of two royal dynasties, Antigonids and Attalids, descended from a noble family of Hippostratoi-Kallippoi from Beroia. If this supposition is correct, there appears yet another argument in favour of C.F. Edson’s theory of a close connection of the Antigonid royal house with Beroia.
