What is "marpessos"

Marpessos was a settlement in the middle Skamander valley of the Troad region of Anatolia. The settlement's name is also spelled , , in ancient sources. It was known in Classical antiquity primarily as the birthplace of the Hellespontine Sibyl Herophile. Its site has been located at Dam Dere approximately 2 km SE of the village of Zerdalilik in the Bayramiç district of Çanakkale Province in Turkey. Despite the similarity of its name and its location on Mount Ida, the settlement is apparently unrelated to the mythological figure Marpessa and her husband Idas. It should likewise not be confused with the Mount Marpessa on Paros.
