Siduse

Sidussa (Ancient Greek: Σίδουσσα or Σιδούσση) was a small town of Ionia, belonging to the territory of Erythrae, noted by Thucydides as a strong place, like Pteleum. Pliny the Elder 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 of Byzantium mentions a town of this name in the territory of Erythrae.
