The present-day Barcelona was an Iberian settlement of the Lacetani (Mela 2,90; Plin. HN 3,22; Ptol. 2,6, 18). During the Civil War, B. was on Caesar's side. B. received the name Faventia Julia Augusta Pia (or Paterna?) Immunis. B. reached its highest peak during Roman imperial times. The city attained its special significance not least because of its bishops -- under the Visigoths, when the decline of Tarraco started.
