"Whether ... the Aravisci migrated into Pannonia from the Osi, a German race, or whether the Osi came from the Aravisci into Germany, as both nations still retain the same language, institutions and customs, is a doubtful matter."--"The locality of the Aravisci was the extreme north-eastern part of the province of Pannonia, and would thus stretch from Vienna (Vindobona), eastwards to Raab (Arrabo), taking in a portion of the south-west of Hungary. ... The Osi seem to have dwelt near the sources of the Oder and the Vistula. They would thus have occupied a part of Gallicia." _Tacitus, Germany, translated by Church and Brodribb, with geographical notes._ ARAWAKS, OR ARAUACAS, The. See AMERICAN ABORIGINES: CARIBS.
