Kyrbissos (Greek, Ancient (to 1453);: Κυρβισσός) was a town of ancient Caria or of Ionia; the ethnonym was Κυρβισσεύς. It was a member of the Delian League since it appears in tribute records of Athens between the years 454/3 and 445/3 BCE paying a phoros of 2000 drachmae.[1] It appears again in a tribute decree of Athens dated to 425/4 BCE.[1] A treaty dated to the 3rd century BCE documents a sympoliteia between Kyrbissos and Teos such that Kyrbissos would be absorbed by Teos but would continue to exist and not be destroyed.[2] Its site is unlocated.[1]
