(Τραγασαί/Tragasaí). Settlement in southeastern Troad at modern Tuzla, to the north of Gülpınar. T. is named after Tragasus, whose daughter Philonomia was married to Tennes , the ruler of Tenedus (EM 763,25). Known for its salt springs (Str. 13,1,48), T. lies in the middle of the Plain of Tuzla (in Antiquity Ἁλήσιον πεδίον/Halḗsion pedíon, 'Salt Plain', Hellanikos FGrH 4 F 34; Plin. HN 31,85). The springs were so profitable that Lysimachus  levied a tax on them (Ath. 3,73d).
