In this paper we discuss Apama’s involvement in the Seleucid power structure. To carry out this project, we rely on two sources of knowledge: the cities named after the queen and an honorific decree of Miletus dated to 299 BCE. The study of these varied informations reveals the mise-en-scène of Apama after the battle of Ipsos (301 BCE). The emphasis on the queen’s activity at this precise moment of History – though she seems to have been active before 299 BCE – and Apama’s inclusion into the ideologic project of the Tetrapolis (ca. 300 BCE) show how important it was to publicize the influence of the queen. Indeed, at the same time, Seleucos – her husband – allies with the Antigonids and marries (300-297 BCE) Stratonike, Demetrios’ daughter. In this context, it is necessary to secure the primacy of Apama in order to prepare and to guarantee Antiochos’ (her son’s) royal legacy. In documentary terms, this conjunction of events – by leaving behind a record of public display of Apama – gives us a unique insight into the structure of the power of the first seleucid queen.
