(Σατνιόεις; Satnióeis). River in Troas (Hom. Il. 6,34; 14,445; 21,87), modern Tuzla Çayı, rises on the southwestern slopes of the Ida , near Gargara. It was on the S. that Homer's city of Pedasus  is supposed to have been (cf. Str. 13,1,50). At Assus the S. is only about 2 km from the sea; it then proceeds west and reaches the sea between Hamaxitus and Larisa  near Gülpınar.
