Eunice (Greek: Eὐνείκη, flourished 1st century, died after 69) was the queen of the Bosporan Kingdom by marriage to King Cotys I.
In the year 1910, a Greek inscription was found on a marble plate in the wall of a house in Anapa, Russia.
This inscription is dated from the reign of her son Rhescuporis I (68-90) (Corpus Regni Inscriptionum Bospor CIRB 1118): Eunice's name has also appeared in surviving bronze coinage from the Bosporan Kingdom.
On the other side of coins, appears with an enclosing wreath with the Greek abbreviations ΒΑΚ, ΒΑΕΥ, ΒΑΕΙΥ and with the trade denomination ΚΔ.
BAK is the royal abbreviations of Cotys I in Greek: BA[σιλέως] K[ότυος], of King Cotys, while ΒΑΕΥ and ΒΑΕΙΥ are the royal abbreviations for Eunice in Greek: BA[σιλίδος] E[ὐνείκης], of Queen Eunice.
Perhaps Nero wanted to minimise the role, power and influence of local client rulers and desired the Bosporan to be completely governed by the Roman state.
