Sidussa
Greek colony in ancient Ionia
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.
Sidussa was a member of the Delian League since it is mentioned in tribute records to Athens at least between the years 450/49 and 430/29 BCE.
Thucydides places it in the territory of Erythrae and says that, like Pteleum it was a fortified place that was used by the Athenian army under the command of Leon and Diomedon to attack positions on Chios in the year 412 BCE.
Sidussa's location is tentatively accepted as at Büyük Ada, İzmir Province, Turkey.

This brief starts where responsible research should: with the source description of “Sidussa” as greek colony in ancient Ionia. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as greek colony in ancient Ionia. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Mar 24, 2026. The linked authority identifier is Q29788252. Authority coordinates are 38.659, 26.516. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1854 and 1857.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
