Baetica

One of the three provinces into which the Roman emperor Augustus divided Hispania, the Spanish peninsula. The other two were Tarraconensis and Lusitania. Baetica, called after the River Baetis (now the Guadalquivir), was separated from Lusitania by the River Anas (now the Guadiana), and from Tarraconensis by an imaginary line drawn from the Anas to the promontory of Charidemus on the Mediterranean.
