. "The Oeselians or Osilians were a historical subdivision of Estonians inhabiting Saaremaa (Latin: Oesel or Osilia), an Estonian island in the Baltic Sea. In modern Estonian, they are called saarlased (Estonian pronunciation: [\u02C8s\u0251\u02D0rl\u0251set] \"islanders\"; singular: saarlane), which also applies to present-day inhabitants of the island. They are first thought to be mentioned as early as the 2nd century BC in Ptolemy's Geography III."@en . .
