Ancient Geography, one of the three principal divisions of Gallia Comata (Caesar); bounded by the Garonne, the Pyrenees, and the ocean: this is the Aquitania Caesariana, or Vetus. Augustus set the different boundaries, viz. the Loire, the Cevennes, the Pyrenees, and the ocean (Strabo). It was called Gallia Aquitanica (Pliny); and in the old Notitia Provincia Aquitanica. The people are called Aquitanii (Caesar). Now comprising Guienne (which seems to be a corruption of Aquitania) and Gafcony.
