Loyal wives or just concubines ..?

The well known Heroon at the Toumba cemetery consist of a shaft housing of two very rich and apparently simultaneous burials, a male cremation and a female inhumation, assumed as the woman being the warrior's consort probably sacrificed during his husband's funerals. In this paper I argue is that if we can trust the anthropological identification and the simultaneity of both depositions, then we can consider these women as concubines better than wives, if we compare this evidence with contemporary archaeological funerary sites and the with the ancient Greek oral and literary tradition.
