[1] (At the southern tip of the present-day Gallipoli peninsula; Barrington Atlas map 51 grid G4.) Very similarly in ps.-Zonaras. The Suda's source for this glossing is Harpokration s.v. (epsilon31 Keaney), but NB: the headword there is the nominative 'Elaious', whereas in the Suda (and ps.-Zonaras) it is 'Eleounta', i.e. not only with the post-classical spelling of the toponym but also in the accusative. If 'Elaiounta' (sic) is quoted from somewhere, extant possibilities begin with Herodotus and Thucydides.
