(Γῆλαι /Gēlai, Str. 11,5,1, cf. 11,7,1; 11,8,1; Γηλύς /Gēlýs, Steph. Byz. s.v. Γ.; Γηλοί /Gēloí, Dionys. Per. 1019 [GGM II, 167]). Median tribe of Scythian origins, first mentioned by Strabo (according to Theophanes of Mytilene), who inhabited the south-western shores of the Caspian Sea. Some ancient authors (Plin. HN 6,48; Ptol. 6,2,5) identified them with the  Cadusii. The tribe's name lives on in the region's (or rather the Sassanid province's) modern name of Gı̄lān (middle Persian Gēlān).
