As Sparta was a Dorian polis, many of its heroic cults have been interpreted as part of Sparta’s so-called ‘Achaian’ policy, which introduced Achaian heroes in order to legitimise its territorial claims in the Peloponnese. This article reviews the topic of ethnicity as a motivating factor behind the instigation of hero-cults in the Greek world. It focuses on three case studies in Sparta: the cult of Agamemnon, the transfer of the bones of Orestes, and of those belonging to his son (...) Teisamenos. By examining the evidence within Greek religious tradition and by placing it in its historical context, I challenge the persisting views associated with the cults of these heroes. In turn, I argue that Sparta worshiped these heroes because they were traditionally local and their foundation was not driven by any ethnic consideration. I emphasise how there has been a scholarly tendency to overuse political interpretation in the understanding of these cults, while their religious significance has been frequently neglected. (shrink)
