SIDUSSA(Σίδουσσα), a small town of Ionia, belonging to the territory of Erythrae. (Thucyd. 8.24; Steph. B. s. v.) Pliny (Plin. Nat. 5.38) erroneously describes it as an island off the coast of Erythrae. It is probable that the place also bore the name of Sidus (Σιδοῦς), as Stephanus B. (s. v.) mentions a town of this name in the territory of Erythrae.
