EOLIS, or EOLIA (anc. geog.), a country of the Hither Asia, settled by colonies of Eolian Greeks. Taken at large, it comprehends all Troas, and the coast of the Hellepont to the Propontis, because in those parts there were several Eolian colonies: more strictly, it is situated between Troas to the north, and Ionia to the south. The people are called Eolis, or Eolii.
